Radius Search: Cities & ZIP Codes Within Any Distance
Choose a city and a radius to list the places around it.
How does the radius search work?
Pick a center city and a radius from 5 to 200 miles, then press the button. The tool measures the straight-line distance from the center to every place in our data that has a page, lists those inside the circle from nearest to farthest, and totals the places and the ZIP codes they use. The calculation runs in your browser, so nothing you type is sent to our server.
What can you do with the results?
- Service areas: plumbers, movers, tutors and installers can list every town they cover.
- Delivery and sales territories: see which places and ZIP codes fall inside a drive-time guess.
- Relocation research: find the communities within commuting range of a job.
- Planning: check how many places sit inside a given distance of a facility or event.
What does the downloaded CSV contain?
The file has one row per place with its name, state, distance in miles, estimated population and ZIP codes. You can open it in Excel or Google Sheets. The data is licensed to this site under Creative Commons Attribution 4.0, so if you republish the list, credit the SimpleMaps US Cities Database. Population figures are estimates, as explained in our population guide.
How accurate is a radius?
The tool uses great-circle distance, which ignores roads, rivers and mountains. A place 40 miles away in a straight line may be 55 miles by road. ZIP codes are delivery areas rather than circles, so a code listed for a place near the edge may reach slightly beyond the radius. For a drive-time boundary, use a mapping service after you have a rough list from this tool.
How do you choose a good radius?
For deliveries and home services, 15 to 30 miles is a common starting point in dense metro areas, because traffic makes longer trips slow. In rural areas a radius of 50 to 100 miles may still be a reasonable drive. For commute research, think in minutes rather than miles, then convert: at an average of 40 miles per hour, a 30-minute commute is about 20 straight-line miles once you allow for roads. Run the tool at two or three radii and compare how many places and ZIP codes you gain with each step.
Where can you see ready-made radius pages?
The largest 300 cities each have a page with the 10, 25, 50 and 100-mile counts, a table of nearby places and the ZIP codes within 25 miles. Start from the state directory, open a large city and follow its radius link, or compare places with the distance calculator.
