A census-designated place ( CDP ) is a concentration of population defined by the United States Census Bureau for statistical purposes only.
81-607: Rosharon ( / r oʊ ˈ ʃ ɛər ən / roh- SHAIR -ən ), is a census-designated place (CDP) in Brazoria County , Texas , United States, at the intersection of Farm to Market Road 521 and Farm to Market Road 1462 . As of the 2010 census , it had a population of 1,152. There are areas outside of the CDP, with Rosharon postal addresses, in Fort Bend County . The Rosharon town site went unnamed during its early years. The area
162-534: A census designated place in the 2010 U.S. Census . In 1985 Yani Rose Keo, a Cambodian American , established a farm in an area called "Little Cambodia", in Brazoria County , near Rosharon. Terrence McCoy of the Houston Press stated that there were "perhaps" 90 families of Cambodian origin living there. In the 2000s (decade) the farmers got into a dispute with the Texas Parks and Wildlife Department (TPWD) over
243-463: A postal inspector . The phrase "zone improvement plan" is credited to D. Jamison Cain , a Postal Service executive. The post office credits Moon with only the first three digits of the ZIP Code, which describe the sectional center facility (SCF) or "sec center". An SCF is a central mail processing facility with those three digits. The fourth and fifth digits, which give a more precise locale within
324-421: A CDP have no legal status and may not always correspond with the local understanding of the area or community with the same name. However, criteria established for the 2010 census require that a CDP name "be one that is recognized and used in daily communication by the residents of the community" (not "a name developed solely for planning or other purposes") and recommend that a CDP's boundaries be mapped based on
405-552: A bucket of buttermilk and a dipper to the railroad station to give the engineer and crew a drink. George Wetmore Colles, Jr. (1871–1951), an electrical and mechanical engineer educated at Yale University (BA 1892) and the Stevens Institute of Technology , bought property in the area around 1900 and called his estate the Rose of Sharon Garden Ranch after the many Cherokee Roses ( Rosa laevigata ) that grew there. Colles also designed
486-555: A cartographic practice. As ZIP Codes are not polygons, but collections of mail routes and points, they are unsuitable for publication or distribution of most data. Polygons for ZIP Codes are not released by the USPS and instead interpolated by 3rd party vendors. These interpolations introduce topological errors and are not standard between vendors. The USPS often discontinues, splits, or otherwise modifies ZIP Codes, making continuous space-time analysis challenging, leading to issues with both
567-429: A city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, the new format was not adopted universally by the public; it eventually became obsolete with modern technology. In general, mail is read by a multiline optical character reader (MLOCR) that almost instantly determines
648-476: A consequence, ZIP Code "areas" can overlap, be subsets of each other, or be artificial constructs with no geographic area (such as 095 for mail to the Navy, which is not geographically fixed). In similar fashion, in areas without regular postal routes ( rural route areas) or no mail delivery (undeveloped areas), ZIP Codes are not assigned or are based on sparse delivery routes, and hence the boundary between ZIP Code areas
729-498: A full, correct ZIP+4 Code and an additional two digits representing the exact delivery point . Furthermore, mail must be sorted in a specific manner to an 11-digit code with at least 150 mailpieces for each qualifying ZIP Code and must be accompanied by documentation confirming this. These steps are usually done with PAVE-certified software that also prints the barcoded address labels and the barcoded sack or tray tags. The assignment of delivery point digits (the 10th and 11th digits)
810-517: A long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska , which was changed from NB to NE in 1969 at the request of the Canadian Post Office Department , to avoid confusion with New Brunswick . Robert Moon is considered the father of the ZIP Code; he submitted his proposal in 1944 while working as
891-463: A package. As of October 2019 , there are 41,702 ZIP Codes in the United States. Due to convenience, ZIP Codes are used not only for tracking of mail, but also commonly for gathering geographical statistics in the United States by some researchers. ZIP Codes are not created for statistical analysis, thus use for statistical analysis is heavily criticized for numerous reasons and advised against as
SECTION 10
#1732855325779972-455: A population of at least 10,000. For the 1970 Census , the population threshold for "unincorporated places" in urbanized areas was reduced to 5,000. For the 1980 Census , the designation was changed to "census designated places" and the designation was made available for places inside urbanized areas in New England. For the 1990 Census , the population threshold for CDPs in urbanized areas
1053-553: A post office to close and its associated ZIP Code to be deallocated. For example, Centralia, Pennsylvania 's ZIP Code, 17927, was retired in 2002, and ZIP Codes for Onoville (14764), Quaker Bridge (14771) and Red House (14773) in New York were prevented from going into use in 1964 in preparation for the Kinzua Dam 's completion. Each ZIP Code has one or more "postal city" names assigned to it. Since ZIP Code boundaries are based on
1134-593: A process called ZIP-code marketing. Point-of-sale cashiers sometimes ask consumers for their home ZIP Codes. Besides providing purchasing-pattern data useful in determining the location of new business establishments, retailers can use directories to correlate this ZIP Code with the name on a credit card to obtain a consumer's full address and telephone number . ZIP-Coded data are also used in analyzing geographic factors in risk, an insurance and banking industry practice pejoratively known as redlining . This can cause problems, e.g. , expensive insurance, for people living near
1215-641: A region (if applicable) often gets the first ZIP Codes for that region; afterward, the numerical order often follows the alphabetical order. Because ZIP Codes are intended for efficient postal delivery, there are unusual cases where a ZIP Code crosses state boundaries, such as a military facility spanning multiple states or remote areas of one state most easily serviced from a bordering state. For example, ZIP Code 42223 serves Fort Campbell , which spans Christian County, Kentucky , and Montgomery County, Tennessee , and ZIP Code 97635 includes portions of Lake County, Oregon , and Modoc County, California . In general,
1296-463: A study period. Datasets providing a similar approximate geographic extent to ZCTA are commercially available. Despite these issues, ZCTAs are still very popular with researchers in fields like epidemiology, and among government agencies, with some states employing them to publish and distribute public health data during the COVID-19 pandemic. The data is often used in direct mail marketing campaigns in
1377-562: A town with a high crime rate and sharing its ZIP Code, while they live in a relatively crime-free town. (See Elkins Park, Pennsylvania, above.) California outlawed this practice in 2011. ZIP Codes may not currently be used to identify existing legislative districts. Although the website of the United States House of Representatives has a "Find Your Representative" feature that looks up congressional districts based on ZIP Codes alone, it often returns multiple districts corresponding to
1458-400: A variety show that the post office used to explain the importance of using ZIP Codes. In 1983, the U.S. Postal Service introduced an expanded ZIP Code system that it named ZIP+4 , often known as "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as
1539-575: Is a system of postal codes used by the United States Postal Service (USPS). The term ZIP was chosen to suggest that the mail travels more efficiently and quickly ( zipping along ) when senders use the code in the postal address . The Philippine Postal Corporation also uses this terminology for the postal code system in the Philippines . Introduced on July 1, 1963, the basic format comprised five digits. In 1983, an extended code
1620-648: Is intended to ensure that every single mailable point in the country has its own 11-digit number. The delivery-point digits are calculated based on the primary or secondary number of the address. The USPS publishes the rules for calculating the delivery point in a document called the CASS Technical Guide. ZIP Codes designate delivery points within the United States (and its territories). There are four types of ZIP Codes: Unique ZIP Codes are used for governmental agencies, universities, businesses, or buildings receiving sufficiently high volumes of mail to justify
1701-495: Is located in Rosharon. Rosharon is the current home of Skydive Spaceland Houston, a major skydiving center with a dedicated airstrip and landing area on the northeastern corner of FM 521 and FM 1462. The Rosharon Volunteer Fire Department (RVFD) provides fire services for Rosharon. In the 1940s Rosharon community members, wanting to start a fire department, met with Brazoria County officials and purchased firefighting equipment. From

#17328553257791782-611: Is that assigned to the headquarters of Walmart (72716). They may also be assigned to a single program, such as the Postal Service's Operation Santa Claus program, under which children are invited to write to Santa Claus at "North Pole 88888". An example of a PO box-only ZIP Code is 22313, used for boxes at the main post office in Alexandria, Virginia , including those used by the United States Patent and Trademark Office . In
1863-438: Is therefore committing the ecological fallacy by attempting to disaggregate aggregate data. As ZIP Codes are not continuous, not everyone in the United States has one, and there are ZIP Codes for non-populated or geographic areas, resulting in there not being one ZCTA for every ZIP Code. ZCTAs are not updated as frequently as the USPS updates ZIP Codes, resulting in further temporal analysis issues when ZIP Codes change during
1944-522: Is undefined. For example, some residents in or near Haubstadt, Indiana , which has the ZIP Code 47639, have mailing addresses with 47648, the ZIP Code for neighboring Fort Branch, Indiana , while others living in or near Fort Branch have addresses with 47639. Many rural counties have similar logistical inconsistencies caused by the aforementioned sparse delivery routes, often known as Rural Routes or by some other similar designation. There are generally no ZIP Codes for deliveries to other countries, except for
2025-555: Is used as a building number, while the city in which the embassy or consulate is located is combined with the word "Place" to form a fictional street name. Each mission uses a ZIP+4 Code consisting of 20521 and the diplomatic pouch number. For example, the U.S. Embassy in India has this address in India's postal system: Embassy of the United States of America Shantipath, Chanakyapuri, New Delhi, National Capital Territory of Delhi, 110021 as well as this U.S. address: Embassy of
2106-643: The 1890 Census , in which the Census mixed unincorporated places with incorporated places in its products with "town" or "village" as its label. This made it confusing to determine which of the "towns" were or were not incorporated. The 1900 through 1930 Censuses did not report data for unincorporated places. For the 1940 Census , the Census Bureau compiled a separate report of unofficial, unincorporated communities of 500 or more people. The Census Bureau officially defined this category as "unincorporated places" in
2187-455: The 1950 Census and used that term through the 1970 Census. For the 1950 Census, these types of places were identified only outside " urbanized areas ". In 1960 , the Census Bureau also identified unincorporated places inside urbanized areas (except in New England , whose political geography is based on the New England town , and is distinctly different from other areas of the U.S.), but with
2268-914: The Alvin ISD . Manvel High School , Manvel Junior High, and E.C Mason Elementary. In the neighborhoods west of Chocolate Bayou, along the north side of F.M. 1462, students attend Alvin Primary, Alvin Elementary, Fairview Junior High and Alvin High School in Alvin . Prior to the opening of Hightower High School, Elkins High School served parts of the Rosharon area in Fort Bend County. The Texas Legislature designated portions of Angleton ISD that by September 1, 1995 had not been annexed by Alvin Community College as in
2349-720: The Brazosport College zone. As Rosharon is not in the maps of Alvin CC, it is in the Brazosport College zone. There was a section of H.B. No. 2744, filed on March 6, 2007, which would have changed the boundary between Alvin CC and Brazosport CC to put Rosharon in the Alvin CC service boundary. Census-designated place CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places , such as self-governing cities , towns , and villages , for
2430-602: The East Coast , such as 02115 ( Boston ), 10001 ( New York City ), 19103 ( Philadelphia ), 21201 ( Baltimore ), 20008 ( Washington, D.C. ), 30303 ( Atlanta ), and 33130 (Miami) (these are only examples, as each of these cities contains several ZIP Codes in the same range). From there, the numbers increase heading westward and northward east of the Mississippi River , southward west of the Mississippi River, and northward on
2511-463: The Mexico–United States border , and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unincorporated areas within the United States are not and have not been included in any CDP. The boundaries of

2592-1002: The West Coast . For example, 40202 is in Louisville , 50309 in Des Moines , 60601 in Chicago , 63101 in St. Louis , 77036 in Houston , 80202 in Denver , 94111 in San Francisco , 98101 in Seattle , and 99950 in Ketchikan, Alaska (the highest ZIP Code). The first digit of the ZIP Code is allocated as follows: The second and third digits represent the sectional center facility (SCF) (e.g. 477xx = Vanderburgh County, Indiana ), and
2673-515: The modifiable areal unit problem (MAUP) and modifiable temporal unit problem (MTUP). As the ZIP Codes are postal routing numbers, individuals and organizations without concrete spatial locations may be given their own number, making it impossible to associate demographic data with them. Demographic data is not consistent between ZIP Codes, and no effort is made to ensure they are proper enumeration units for analysis. As ZIP Codes are not made with
2754-692: The 1940s until 2004 the firefighting department received all of its support from fundraising events, private donations, and small contributions from the Brazoria County government. The volunteer group organized in 1956, and in 1986 the Rosharon Volunteer Fire Department, Inc. incorporated as a non-profit corporation. In 2002 taxpayers formed the Brazoria County Emergency Services District #3, which provides EMS services. The United States Postal Service operates
2835-508: The Angleton schools. Students began being bussed to Angleton in the late 1900s, a practice that continues to this day. Church meetings were first held in a former school, then in a tavern that community members had bought and converted into a church. Eventually a brick church was constructed. The South Texas Water Company located in Rosharon in 1935, and its fresh watercanals for irrigating rice brought some seventy-five to eighty rice farmers to
2916-445: The Census Bureau considers some towns in New England states, New Jersey and New York as well as townships in some other states as MCDs, even though they are incorporated municipalities in those states. In such states, CDPs may be defined within such towns or spanning the boundaries of multiple towns. There are a number of reasons for the CDP designation: ZIP code A ZIP Code (an acronym for Zone Improvement Plan )
2997-519: The Greater Houston area. There are four Texas Department of Criminal Justice (TDCJ) prison units near Rosharon. Ramsey (formerly Ramsey I), Stringfellow (formerly Ramsey III), and Terrell (formerly Ramsey II) are all co-located. In addition Darrington Unit is near Rosharon. The Handbook of Texas stated that the prison authority employees and their family members "added considerably to [Rosharon's] economy." A Schlumberger product center
3078-544: The Rosharon Post Office at 1810 East Farm to Market Road 1462 . Students in the Rosharon census-designated place attend the Angleton Independent School District (AISD) schools. In the 20th century the Rosharon school district was consolidated into the Angleton district, and busing into Angleton began in the late 20th century. Angleton High School serves all district residents. Students in
3159-454: The SCF, were proposed by Henry Bentley Hahn Sr. The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, although the building may include a post office that is open to
3240-493: The United States of America 9000 New Delhi Place Washington, DC 20521-9000 Individuals posted at diplomatic missions overseas are now assigned a Diplomatic Post Office address and unique box number. The ZIP Code identifies the diplomatic mission destination and is different from the diplomatic pouch number in the example above. While delivered through the pouch system, mail to such addresses are not considered "Diplomatic Pouch" materials, and as such must adhere to
3321-574: The ZIP Code which are combined with to use for mapping and data presentation. The process of creating ZCTAs and their use for statistical analysis are heavily criticized in the literature. First, the creation of ZCTAs from Census blocks encounters issues when a Census block straddles multiple ZIP Codes. Addressing this is another instance of the MAUP, and the solution of dividing aggregate units between ZIP Codes causes some individuals to fall into ZCTAs that do not match their ZIP Code. The creation of these units

3402-662: The ZIP Codes 01002 and 01003 for Amherst, Massachusetts ; 01002 is used for mail in town, while 01003 is reserved for the University of Massachusetts Amherst . Until 2001, there were six ZIP Codes lower than 00501 that were numbered from 00210 to 00215 (located in Portsmouth, New Hampshire ) and were used by the Diversity Immigrant Visa program to receive applications from non-U.S. citizens. The numbers increase southward along
3483-486: The ZIP+4 Code must be looked up individually for each box (e.g. using the USPS's official ZIP Code Lookup tool, and being sure to enter just city and state, not the 5-digit ZIP). The ZIP Code is often translated into an Intelligent Mail barcode that is printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender (some word-processing programs such as WordPerfect include
3564-456: The affected area can notify correspondents, order new stationery, etc. In rapidly growing communities, it is sometimes necessary to open a new sectional center facility, which must then be allocated its own three-digit ZIP-code prefix or prefixes. Such allocation can be done in various ways. For example, when a new sectional center facility was opened at Dulles Airport in Virginia, the prefix 201
3645-427: The area surrounding that post office, home and business mail delivery addresses use ZIP Code 22314, a standard ZIP Code. ZIP Codes are numbered with the first digit representing a certain group of U.S. states, the second and third digits together representing a region in that group (or perhaps a large city) and the fourth and fifth digits representing a group of delivery addresses within that region. The main town in
3726-506: The area. By the late 1980s, Rosharon had an estimated population of 500. In 1990 the population was 435. Most residents commute to jobs in nearby towns. Neighborhoods in the surrounding area include; Songbird Ranch Airport (private), Savannah Plantation, Lindell Estates, Lakes of Savannah, Glendale Lakes, Southern Colony, Caldwell Ranch,Chenango Ranch, Coffee Lake, Seven Oaks Ranch, Sun Creek Estates, Sun Creek Ranch, Cold River Ranch, Sterling Lakes and Sierra Vista. Rosharon first appeared as
3807-440: The areas served by each physical post office, they often do not coincide with the boundaries of local government units. For example, suburban and unincorporated areas may share a postal city name with a neighboring municipality, even if no part of its ZIP Code is actually within that city. Delivery services other than the USPS, such as FedEx , United Parcel Service , and DHL , require a ZIP Code for optimal internal routing of
3888-537: The army, and the zone system would enable inexperienced clerks to sort mail without having to learn the delivery area of each city carrier. For example: Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis 16 , Minnesota The "16" is the number of the postal zone in a specific city. By the early 1960s, a more organized system was needed, and non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963. The USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with
3969-653: The assignment to them of exclusive ZIP Codes. Government examples include 20505 for the Central Intelligence Agency in Washington, D.C., and 81009 for the Federal Citizen Information Center of the U.S. General Services Administration (GSA) in Pueblo, Colorado . An example of a university-specific ZIP Code is 21252, which serves Towson University . An example of a private address unique ZIP Code
4050-484: The boundaries for CDPs. The PSAP was to be offered to county and municipal planning agencies during 2008. The boundaries of such places may be defined in cooperation with local or tribal officials, but are not fixed, and do not affect the status of local government or incorporation; the territories thus defined are strictly statistical entities. CDP boundaries may change from one census to the next to reflect changes in settlement patterns. Further, as statistical entities,
4131-419: The boundaries of the CDP may not correspond with local understanding of the area with the same name. Recognized communities may be divided into two or more CDPs while on the other hand, two or more communities may be combined into one CDP. A CDP may also cover the unincorporated part of a named community, where the rest lies within an incorporated place. By defining an area as a CDP, that locality then appears in
SECTION 50
#17328553257794212-455: The center-point of the ZCTAs. ZIP Codes are inherently discrete or point-based data, as they are assigned only at the point of delivery, not for the spaces in between the delivery points. The United States Census Bureau then interpolates this discrete data set to create polygons by attempting to match ZIP Code extents with Census blocks. The resulting aerial units represent the approximate extent of
4293-399: The community water system. Antonio G. Arcaro served as Rosharon's postmaster from 1912 to 1920. The Rosharon post office was discontinued in 1920 and mail was then sent to Sandy Point . The post office reopened in 1936, only to be closed again in 1979. A new post office was dedicated under President Ronald Reagan and operates today. Tom Lochridge (1903–1985) platted the town site. Lochridge
4374-459: The correct ZIP+4 Code from the address—along with the even more specific delivery point —and sprays an Intelligent Mail barcode (IMb) on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point. For post office boxes , the general but not invariable rule is that each box has its own ZIP+4 Code. The add-on code is often one of the following:
4455-401: The county was changed to 208xx codes, while 208xx codes outside that county were changed to 207xx codes. Because Silver Spring (whose postal area includes Wheaton ) has its own prefix, 209, there was no need to apply the reshuffling to Silver Spring; instead, all mail going to 209xx ZIP Codes was simply rerouted to the new sectional center facility. On the other hand, depopulation may cause
4536-559: The farming of water spinach , which the TPWD classified as “Harmful or Potentially Harmful to Exotic Fish, Shellfish and Aquatic Plants.” Ultimately the TPWD allowed the farming of water spinach. "Little Cambodia" sustained damage during Hurricane Ike in 2008, and in Hurricane Harvey in 2017. As of 2015, 77583, the ZIP code of Rosharon, Texas, has the highest concentration of Cambodian Americans in

Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mail. This requires more than just a simple font ; mailing lists must be standardized with up-to-date Coding Accuracy Support System (CASS)-certified software that adds and verifies
4698-530: The first three digits designate a sectional center facility , the mail sorting and distribution center for an area. A sectional center facility may have more than one three-digit code assigned to it. For example, the Northern Virginia sectional center facility in Merrifield is assigned codes 220, 221, 222, and 223. In some cases, a sectional center facility may serve an area in an adjacent state, usually due to
4779-423: The fourth and fifth digits represent the area of the city (if in a metropolitan area ), or a village/town (outside metro areas), e.g. 47722 (4=Indiana, 77=Vanderburgh County, 22= University of Evansville area). When a sectional center facility's area crosses state lines, that facility is assigned separate three-digit prefixes for the states that it serves. In some urban areas, like 462 for Marion County, Indiana ,
4860-788: The geographic extent associated with inhabitants' regular use of the named place. There is no provision, however, that this name recognition be unanimous for all residents, or that all residents use the community for which the CDP is named for services provided therein. There is no mandatory correlation between CDP names or boundaries and those established for other human purposes, such as post office names or zones, political precincts, or school districts. The Census Bureau states that census-designated places are not considered incorporated places and that it includes only census-designated places in its city population list for Hawaii because that state has no incorporated cities. In addition, census city lists from 2007 included Arlington County, Virginia 's CDP in
4941-697: The independent countries of the Federated States of Micronesia , the Republic of the Marshall Islands , and the Republic of Palau , each of which is integrated into the U.S. postal system under a Compact of Free Association . Another exception is ZIP Codes used for overseas stations of U.S. armed forces. Mail to U.S. diplomatic missions overseas is addressed as if it were addressed to a street address in Washington, D.C.

For example, 739 in Oklahoma is assigned to Amarillo, Texas ; 297 in South Carolina is assigned to Charlotte, North Carolina ; 865 in Arizona is assigned to Albuquerque, New Mexico ; and 961 in California to Reno, Nevada . Many of the lowest ZIP Codes, which begin with '0', are in the New England region. In the '0' region are New Jersey (non-contiguous with

However, there is no uniform rule, so
5184-509: The list of two-letter state abbreviations which are generally written with both letters capitalized. An earlier list, publicized in June 1963, had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59 , the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by
5265-543: The list with the incorporated places, but since 2010, only the Urban Honolulu CDP, Hawaii, representing the historic core of Honolulu, Hawaii , is shown in the city and town estimates. The Census Bureau reported data for some unincorporated places as early as the first census in 1790 (for example, Louisville, Kentucky , which was not legally incorporated in Kentucky until 1828), though usage continued to develop through
5346-440: The mailing regulations of the host country. An example address is: JOHN ADAMS UNIT 8400 BOX 0000 DPO AE 09498-0048 Like area codes , ZIP Codes are sometimes divided and changed, especially when a rural area becomes suburban . Typically, the new codes become effective once announced, and a grace period (e.g., one year) is provided in which the new and old codes are used concurrently so that postal patrons in
5427-406: The part of researchers. In an attempt to satisfy demand " by data users for statistical data by ZIP Code area", the U.S. Census Bureau calculates approximate boundaries of ZIP Code areas, which it calls ZIP Code Tabulation Areas (ZCTAs). Statistical census data is then provided for these approximate areas. The geographic data provided for these areas includes the latitude and longitude of
5508-482: The public, and most of their employees work the night shift . Items of mail picked up at post offices are sent to their own SCFs in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits as assigned generally coincided with the older postal zone number. For example: Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis, MN 554 16 In 1967, these became mandatory for second- and third-class bulk mailers, and
