Our system operates on a comprehensive dataset of 31,146,040 unique 5 digits ZIP codes, including ZIP+4. Each ZIP code is associated with its respective county and city, providing accurate and detailed location information.
With each request, whether GET or POST, our randomizer selects a different ZIP code from this vast dataset, ensuring that each query provides a new result. This approach guarantees that no two queries will return the same ZIP code consecutively, making the process highly dynamic and reliable.
In addition to generating ZIP codes, we automatically provide information about the corresponding county and city for each generated ZIP, giving you a full snapshot of the location with every result.
If, for any reason, you're unable to select a state in the form, we've made it easy for you! We’ve created dedicated pages for each state, allowing you to explore ZIP codes specific to your chosen location. Simply select the state you’re interested in from the list below. Each state is presented in a grid layout with three columns to make browsing simple and convenient.
