USPS City Versus Census Geography
USPS City Versus Census Geography
Skip Navigation
The U.S. Census Bureau relies on an accurate postal address and the U.S. Postal Service (USPS) to deliver census correspondence to most households. A postal address typically is composed of house number, street, city, state, and ZIP CodeTM. The mailing address for a residence is not used to assign housing units to the proper political jurisdiction or census geography. Instead, the Census Bureau uses the physical location of a housing unit to assign it to the proper geographic areas. The Census Bureau recognizes that the Post Office “city” name associated with a particular ZIP Code in the mailing address for a residence may differ from the legal municipality or district in which the housing unit is actually located. In addition, the “city” name(s) used by the USPS to identify a specific ZIP Code or Post Office may not be the name that residents serviced by the Post Office consider themselves to reside in.
Figure 1 above illustrates the approximate area (using aggregations of Census Bureau-defined ZIP Code Tabulation Areas (ZCTAs)) of the Waterloo “postal city” based on the USPS’s preferred or recommended city name for that ZIP Code. This area includes most, but not all, of the legal boundaries of Waterloo city, and parts of Elk Run Heights city and Hudson city. In addition, this “postal city” includes area that is part of unincorporated Black Hawk County, including Washburn census designated place (CDP). Addresses in this area have “Waterloo” as the preferred city in their mailing address.
Figure 2 below shows the three ZCTAs (50701, 50702, and 50703) that comprise the Waterloo «postal city.» Although each of these ZIP Codes has a “Waterloo” mailing address, they do not follow legal city boundaries and frequently extend beyond the actual city limits of Waterloo. Census data are tabulated to the jurisdiction where the housing unit is physically located, not based on the city name used for the mailing address.
For example, a housing unit located in Washburn CDP with a “50702” ZIP Code is included in the census data for Washburn CDP, not Waterloo city.
The USPS provides the Census Bureau with a data file, the City State Product, which identifies the preferred or recommended city name associated with each ZIP Code. Figure 3 below shows a section of the City State Product with the ZIP Codes and the preferred or recommended city name highlighted for the ZIP Codes shown in the map above.

The Census Bureau built and verified its address list for the 2020 Census using advanced technology, strong partnerships with tribal, state, and local governments, federal agencies like the U.S. Postal Service, and carefully managed census operations. During in-office and in-field census operations, housing unit locations were identified, verified, and assigned to a series of precise geographic codes, together called a “geocode,” using geospatial technologies.
This geocode includes the census block and surrounding geography, including the municipality, tribal, or county code as appropriate. Data that result from the 2020 Census are tabulated using these geocode assignments for each household, not the «postal city» name in the mailing address assigned to the household. Therefore, each census tract, voting district, school district, tribal area, county, municipality, and other geographic area receives accurate results from the census.
In addition, the Census Bureau provided tribal, state, and local governments an opportunity to review and provide feedback on the address list we developed for their community through the 2020 Local Update of Census Addresses, or LUCA Program. Participating tribal, state, and local officials verified that the Census Bureau accurately coded each address on the list to the correct and authoritative geographic codes, regardless of the “postal city” name used by the USPS for delivering mail.

How to Check a ZIP Code: Manual vs Automatic
What Is a ZIP Сode?
A ZIP code is a five-digit code that United States Postal Service uses to designate delivery routes and service areas. Based on the ZIP-code system, letters reach specific facilities for sorting mail. Sorting enables mail carriers to deliver high volumes of mail more quickly and easily.
In the United States, ZIP codes are used to deliver domestic mail. There are usually no ZIP codes for mailing to other countries.
A ZIP code is indicated alongside the address after the name of the city and state abbreviation.
For example, the correct address format will look like this:
JANE EYRE
1955 MARINA STREET
NEW ORLEANS LA 70112
In this address, 70112 is a ZIP code.
How to Read a ZIP Code
The first three digits represent the sectional center facility connected with this code (e.g., codes starting from 1 mean New York). The fourth and fifth digits stand for the area of the city or town.

What is the zip code for…X? ZIP code Lookups and Map
If you want to know the ZIP code for a specific geographic location, you can use ZIP code lookups or the US map.
ZIP code lookup tools automatically generate ZIP codes based on an address or city & state data. They can also do a reverse search and find cities by ZIP code.
To manually find a ZIP code, use one of the following ZIP code lookups:
- USPS ZIP code lookup services
- United States ZIP Codes

Automated address data enrichment
If you run a business that depends on mail delivery, you will need to format and verify thousands of addresses automatically. Manual ZIP code lookups won’t work.
Inkit Verify is one of the automated address validation tools you can adopt. It autocompletes shipment addresses as users type them and also verifies your existing records. This tool adds ZIP code details if necessary and detects incomplete addresses. As a result, your address database is always updated and accurate.
OTHER FAQ
- Do ZIP codes represent geographical areas?
Even though sometimes ZIP codes and geographical areas overlap, ZIP codes don’t represent regions.
ZIP codes are just delivery routes or groups of addresses.
- Is postal code the same as ZIP code?
A postcode is a generic term, whereas the ZIP codes are used only in the US postal system. Besides, postal codes can consist of both numbers and letters, whereas ZIP codes include only numbers.
- ZIP codes vs. ZIP+4 codes: What’s the difference?
ZIP+4 is a new ZIP code standard introduced in 1983 to enhance the accuracy of mail delivery. It uses the standard five-digit ZIP code plus four additional digits. These digits signify a small delivery area (e.g., street, city block, PO box). ZIP+4 codes are not mandatory and are usually assigned automatically at the mail sorting centers. Therefore, if you want to send a letter, a basic ZIP code will be enough for a post office to complete the delivery.

Question
Why does the ArcGIS Business Analyst web application return incorrect geocoding results for some zip code areas?
Answer
In some cases, attempting to geocode in an ArcGIS Business Analyst web application by importing an Excel file with zip codes returns invalid results.
Although zip code searches may return valid results from other sources such as Google, zip codes are not recognized by ArcGIS Business Analyst as valid addresses.
Note : Postcode zones are created for mail delivery, but are not standard census geographic areas for data reporting. Although these zip codes are associated with a city or place according to the USPS notation, they are not recognized in Esri datasets.
For example, the zip code area ‘10981’ does not exist in the ‘United States ZIP Code Boundaries 2018’ layer in the ArcGIS Living Atlas of the World.
In ArcGIS Business Analyst, searching for «10981» returns ‘Sugar Loaf, NY’. However, it is in a different postcode area — «10918».
In most cases, invalid postcodes are part of a larger area of postcodes. Therefore, continuing the geocoding workflow by clicking button Add matches to map without correcting invalid zip codes does not affect analysis. ArcGIS Business Analyst creates a layer with all valid zip code areas from the imported Excel file.
