ZIP+4 Codes are special 4-digit codes appended to 5-digit ZIP Codes that help the USPS to route mail efficiently. When added to mail, the last 4 digits of ZIP Code numbers identify segments of USPS delivery routes.
ZIP+4 Codes are 4-digit codes appended to the original 5-digit USPS ZIP Codes. Using the full ZIP Code with the extra 4 digits when mailing via the USPS ensures the fastest, most accurate mailing possible.
ZIP codes, the postal code system used by the US Postal Service (USPS), were introduced in 1963. Their basic, and most familiar, format consists of five digits that indicate a specific delivery area. In 1983, the USPS introduced the extended ZIP+4 code.
Most payers require the full 9-digit ZIP code for addresses on electronic claims. This rejection typically indicates that the claim includes a ZIP code without the 4-digit extension. All addresses will need to be verified using the USPS ZIP Code Look Up.
A ZIP Code is a postal code used by the United States Postal Service (USPS). Introduced on July 1, 1963, the basic format consisted of five digits.[1] In 1983, an extended ZIP+4 code was introduced; it included the five digits of the ZIP Code, followed by a hyphen and four digits that designated a more specific location.
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: the last four digits of the box number (e.g. PO Box 107050, Albany, NY 12201-7050), zero plus the last three digits of the box number (e.g., PO Box 17727, Eagle River, AK 99577-0727), or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number (e.g., PO Box 77, Juneau, AK 99750-0077). However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box[citation needed] (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).[17]
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 a full, correct ZIP+4 Code and an additional two digits representing the exact delivery point.[citation needed] 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.[citation needed]
In general, 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 the lack of a proper location for a center in that region. 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.
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 was allocated to that facility; therefore, for all post offices to be served by that sectional center facility the ZIP Code changed from an old code beginning with 220 or 221 to a new code or codes beginning with 201. However, when a new sectional center facility was opened to serve Montgomery County, Maryland, no new prefix was assigned. Instead, ZIP Codes in the 207 and 208 ranges, which had previously been assigned alphabetically, were reshuffled so that 207xx ZIP Codes in 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.
Departments are sometimes asked to provide the four digit zip code suffix for their zip code (Zip + 4). For departments that use the campus 38163 zip code, the campus building number serves as the four digit zip code suffix. For more information, view a listing of building names and numbers. Departments that use zip codes other than 38163 can find their four digit zip code suffix by visiting the USPS web site and completing a simple zip code lookup search.
For most addresses there is a 4-digit extension that goes with the standard 5-digit zip code. The Postal Service calls this expanded number Zip+4. By including the Zip+4 number in addresses, the Postal Service can process mail more efficiently. You can find the full zip code for any address on the USPS Zip Code Lookup.
ZIP Plus 4s includes over 63 million records, detailing the 5-digit ZIP Code and 4-digit extensions representing ZIP Code Sector and ZIP Code Segment in the United States. Over 40 postal attribute fields are also included to provide the detail needed to assist in utilizing ZIP Plus 4 data for internal processing and analysis. Additionally, Census block group codes, which include state, county, and tract codes, are provided for each ZIP Plus 4 record. A ZIP Code can represent one side of a street, a floor in a building, or a specific Post Office Box. The ZIP Code Sector (1234) represents a collection of addresses below the ZIP Code level. The ZIP Code Segment (1234) is more specific and always refers to a smaller set of addresses or a single address. In the case of PO Boxes, the ZIP segment is almost always the last two digits of the PO Box number. The four-digit ZIP Code extension is used by the United States Postal Service (USPS) to facilitate efficient mail handling and delivery.
In 1963, the United States Postal Service established the ZIP -- Zoning Improvement Plan -- Code system and assigned a five-digit code to every mailing address in the country. The system allowed postal workers to sort the increasing mail volume faster. In 1981, the ZIP+4 code extension was instituted to further narrow down the geographic area for mail delivery. The USPS website or any USPS location can tell you the four-digit ZIP Code extension for a specific address.
I am looking for Zipcode data with the +4 digits at the end for a City (I can use it by state and clip the points to my municipal boundary), and with edges or geocodes. I called the post office and had no luck (national customer center in Memphis, TN- claimed that their +4 ZIP Code GIS Layer is not for the public).
Some background: The USPS maintains zip codes as sets of delivery zones(5 digit) and routes(+4 digits), usually along streets with address boundaries. USPS does not maintain zip codes in any shape format.
There are several companies that will sell you very accurate zip code data, Maponics being the one that I use. The five digit zip codes from them are pretty accurate. They do not offer zip+4 boundaries but they do have centroids for the +4 routes.
The plus 4 value is based on the address there is not a single number for a city. It is not a universal number for a region as the first 5 digits are -codes.com/learn-about/what-is-a-zip-4-code.asp . You will need to calculate it against some tiger data if you are trying to get every unique value and tie it to a region.
ZIP Plus 4 uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery.The implementation of ZIP Plus 4 adds an extra level of precision that makes delivery easier, and very large organizations often have multiple ZIP Plus 4 codes assigned to the same address. One such example is California Polytechnic State University, in San Luis Obispo.The street address for Cal Poly is 1 Grand Avenue, San Luis Obispo, CA 93407. Within the university, however, different departments or offices have their own ZIP Plus 4 Code. For example:
Use a USPS \"ZIP + four\" code: the first four digits of the six-digit campus mail code are used as the last four digits of the ZIP code for all campus units. So, if the campus mail code is 123456, the U.S. mail ZIP code is 90095-1234.
Box numbers are required for all units that use the 90095 zip code. The box number is 95 plus the first four digits of the campus mail code. So if the campus mail code is 123456, the box number is 951234.
This is the U.S. territories ZIP code website, which contains 861 ZIP codes, 139 cities, 88 counties, and more than 317,020 ZIP+4 codes.
