US ZIP Code Finder

About US ZIP Code Finder

The ZIP Code is a postal area code used by the United States Postal Service (USPS) and is typically written in bold letters. ZIP is the abbreviation for Zone Improvement Plan, which implies that emails can be delivered to their destination more efficiently and quickly. The most basic ZIP number includes five numbers, followed by four additional numbers to enable more precise delivery of emails to their destination. The ZIP number after adding the number is called "ZIP+4".

This US ZIP code finder can help you quickly find the ZIP codes of all cities in the United States. Unlike the common public data online, we have researched a lot of information and found that in the vast majority of online public data, the US ZIP codes/postal codes are only counted at around 35000. This is because some areas, although assigned ZIP code, are not included because they are not common due to the lack of permanent residents. We have collected over 41100 US ZIP codes, which cover all cities in the United States (including Puerto Rico), and even some areas that have been assigned ZIP codes but are currently uninhabited.

Using this US ZIP Code Finder is very simple. If you want to find the ZIP code of a city, you just need to select the state where the city is located, then select the city, and click the "Find" button to see all the postal codes of that city. If you want to find the ZIP codes corresponding to the street in that city, you can use Streets In US to discover.

Except for USPS, other commercial shipping companies such as FedEx, UPS (United Parcel Service), and DHL use ZIP numbers for internal operations. This allows customers to avoid using other path indicators, such as IATA numbers for destination airports or train stations.

The ZIP number is not only used as a location for tracking emails, but also provides geographic data for the United States. Like U S. Census Bureau continuously tracks the latitude and longitude of each ZIP number center point, which is sold by many other companies. These materials are often used in direct email campaigns called "ZIP Number Marketing Planning". The cashier of the store sometimes asks the ZIP number of the customer's address in order to collect information about their shopping patterns. The company or experts will analyze this information to determine where to start a new business. Finally, ZIP numbering data is also used to analyze geographic features.
