United States ZIP Codes – All US Postal Codes by States

This post covers all updated United States ZIP Codes – a list of all US Postal Codes (ZIP codes) for all regions — organized by states, territories, and cities.

According to Wikipedia, A ZIP Code is a United States Postal Service postal code (USPS). The basic format, introduced in 1963, consisted of five digits. An expanded ZIP+4 code was created in 1983, which featured the five digits of the ZIP Code, followed by a hyphen and four numbers indicating a more particular location.

The ‘ZIP’ code, which stands for Zone Improvement Plan, is critical for successful mail and package distribution. Given the recent growth in the e-commerce industry, it’s critical to understand when and how to use the correct USPS ZIP code for your preferred region or state to avoid sending your parcel to the wrong location.

That being stated, you will find all of the postal codes for all of the states in the United States of America – cities, areas, and major regions — on
