ZIP codes within a radius

Every ZIP code within the distance you choose of a place, with its city, state and population, on the map and in a table you can download.

How to use it

  1. Set the centre: an address, your location, or a click on the map.
  2. Set the radius with a preset or a number.
  3. Read the list, nearest first, with the population of each ZIP code.
  4. Press Download CSV or Copy ZIPs.

5 practical uses

  1. Build a mailing list of ZIP codes around a store or a clinic.
  2. Set the delivery or service area of a business by ZIP code.
  3. Target an advert to the ZIP codes near a location.
  4. Find the ZIP codes to filter in a job or property search.
  5. List the ZIP codes for a franchise territory.

The maths behind it

The centre of each ZIP code is compared with the circle centre: a bounding-box test in degrees rules out most, then the haversine great-circle distance decides, and the list is sorted by that distance. The population is the sum over the ZIP codes inside.

Notes

ZIP code positions and populations are the 2020-census ZIP Code Tabulation Areas from SimpleMaps' free database (CC BY 4.0), 33,000 of them. Each is one point, the centre of the area, so a ZIP code counts as inside or outside the circle by that point; a big rural ZIP code is only partly inside in truth. Post-office-box and military ZIP codes are included where they have a position.

For the number of people inside the circle see population within a radius; for a single code, the ZIP code lookup.

Questions and answers

How is "within the radius" decided?

By the centre point of each ZIP code. A ZIP code counts as inside when its centre is inside the circle, so a large rural one can be only partly inside in truth.

Where do the populations come from?

From the 2020 census ZIP Code Tabulation Areas, through the SimpleMaps free database.

Can I get the ZIP codes as a list for a mailing?

Yes. Copy ZIPs puts the codes on the clipboard, comma-separated.
