How to Find a ZIP Code by City and State

May 10, 2026 Updated Jul 9, 2026 Miranda Taylor

If you need to send mail, fill out a form, or complete an online order, knowing the correct ZIP code for a given city and state is essential. In the United States, ZIP codes are tied to specific geographic areas, and many cities have more than one ZIP code depending on neighborhoods or districts. Here’s how you can quickly and accurately find a ZIP code using just the city and state.

Use the USPS ZIP Code Lookup Tool

The most reliable and official way to find ZIP codes by city and state is the United States Postal Service (USPS) ZIP Code Lookup tool. This tool is free and designed specifically for finding ZIP codes based on address information. zors

  1. Go to the USPS ZIP Code Lookup page (look for “ZIP Code™ Lookup” or “Find by City & State”). tools.usps
  2. Choose the option to search “By City and State.” postalpro.usps
  3. Enter the city name in the “City” field and choose or type the state from the dropdown or text box. tools.usps
  4. Click “Search” or “Find.” The tool will display a list of ZIP codes associated with that city and state, often grouped by neighborhood or post office. zors

USPS is the authoritative source, so this method is especially useful for official documents, shipping labels, or business addresses. postalpro.usps

Try Third‑Party ZIP Code Lookup Sites

Many free third‑party websites also let you search ZIP codes by city and state. These sites can be convenient if you want extra details such as maps, counties, or demographics. zipcodestogo

  • Enter the city name and state in the search box and wait for matching ZIP codes to appear.
  • Results typically show the ZIP code, city, county, and sometimes a map link so you can visualize the service area. unitedstateszipcodes

Popular examples include “ZIP Code lookup”‑style sites that aggregate ZIP‑code data by city and state, making it easy to browse or copy the code for your mailing address. zipcodestogo

Check Maps or GPS Apps

If you are on a smartphone or tablet, maps and GPS apps like Google Maps or Apple Maps can also reveal ZIP codes. This is especially handy when you are traveling or dealing with a physical address rather than a general city name. help.talkspace

  • Open your preferred map app and search for the city and state.
  • Tap on the specific address or location; the details pane often includes the ZIP code along with the city and state. about.usps

This method works well if you already know the exact street address but just need confirmation of the ZIP code. help.talkspace

Quick Tips for Accuracy

  • If a city has multiple ZIP codes, choose the one that matches the neighborhood or post office for the address you are mailing to. zors
  • When in doubt, double‑check your ZIP code using the USPS tool, since it powers most official mail and shipping services. tools.usps
  • For business or high‑volume mailing, consider using ZIP+4 codes (extra four digits) to help with faster, more accurate sorting. tools.usps

By using these simple methods, you can quickly find the correct ZIP code for any U.S. city and state, helping your mail arrive on time and your forms stay error‑free. zipcodestogo

Great write-up! Quick question: does this apply to PO Boxes as well, or is the layout different?

About U.S. ZIP Codes

ZIP codes are a United States Postal Service system introduced in 1963 to make mail routing more accurate and efficient. The standard format uses five digits, while ZIP+4 adds four more digits for a more precise delivery segment.

ZIP codes cover the United States, its territories, military mail routes, and other USPS delivery points. This directory organizes that data for practical lookup by ZIP code, city, county, and state.
