Find ZIP Codes in a Radius

Type a centre and a radius in miles and every ZIP code whose centre falls inside is listed, nearest first.

How to use it

  1. Type an address, city or ZIP as the centre, or use your location, or click the map.
  2. Set the radius, in miles or kilometres, or pick one of the presets.
  3. Press "Find ZIP codes". The list, the circle and every ZIP centre appear together.
  4. Download the list as CSV for a mailing or a spreadsheet.

How it works

The centre is geocoded once; everything after that happens in your browser. All 33,791 ZIP Code Tabulation Areas from the Census 2025 Gazetteer, each with its centre point, city, state and ACS 2020-2024 population, are loaded as one 1.9 MB file and filtered by great-circle distance from the centre.

A ZIP is included when the centre of its ZCTA is inside the circle. A ZIP whose area crosses the circle edge is listed or not depending on where its centre falls, so at the edge the list is approximate. Post-office-box ZIPs have no area and are not in the list. The city is the place with the largest land overlap in the Census ZCTA-to-place relationship file, or the county where no place overlaps.

Questions

How do I get a list of ZIP codes within 10 miles of an address?
Type the address, leave the radius at 10 miles and press "Find ZIP codes". Every ZIP whose centre is within 10 miles is listed with its city, state, population and distance, and the "Download CSV" button saves the list.
Are these ZIP codes or ZCTAs?
ZCTAs, the Census Bureau's area version of ZIP codes. They match the postal ZIPs for almost every populated area, but unique ZIPs for single buildings and PO boxes have no area and do not appear.
Is the distance to the ZIP boundary or its centre?
To the centre point of the ZIP area. Part of a large rural ZIP can be well inside the circle while its centre is outside, and it would then not be listed.
How many ZIP codes can it list?
All of them. The radius is capped at 500 miles; a circle that size around Kansas City holds about half the ZIP codes in the country and the table shows the first 2,000 with the CSV carrying the rest.
