Every ZIP code in a city
✓ Free, no sign-up Open CityZips →CityZips answers one question: what are all the ZIP codes in this city? Type a U.S. city and state, pick it from the suggestions, and you see the whole list.
Each ZIP shows its county and type, such as standard, P.O. Box only or unique (a single big organization). Tap any ZIP code to copy it.
After the first visit it works offline, so you can look up ZIP codes even with a weak signal.
It is useful for filling in forms, mailing, setting up service areas, or checking that a ZIP code really belongs to a city.
CityZips comes from Zip Code Nation, the makers of the Zip Code USA database, which is updated monthly. If you need every ZIP code in the country for your own software or spreadsheets, Zip Code USA has it.
Free, no account, nothing to learn.
It runs in the web browser on an iPhone, Android phone, tablet or computer. To keep it handy, open it and use your browser's Add to Home Screen option, and it will sit on your phone like any other app.
