ZIP code radius search
Enter a ZIP or postal code and a radius to get every code inside the circle, sorted by distance, on a map and as a CSV download.
Who uses radius searches
- Marketing teams upload ZIP code lists to Google Ads, Meta Ads and direct-mail tools to target everyone within driving distance of a store.
- Delivery and service businesses define their service area as “all ZIP codes within 25 miles”.
- Developers build store locators and “near me” searches.
Automate it with the API
See the ZIP code distance and radius API page for limits, credits and use cases.
The same search is one request to the zipcodestack API:
curl "https://api.zipcodestack.com/v1/radius?code=10001&radius=5&country=us&unit=miles" \
-H "apikey: YOUR-API-KEY"
Each result contains the code, city, state and distance, sorted from the centre. 300 requests per month are free.
