QUESTIONS

How far can the radius go?
Up to 500 miles. Results come back nearest first, up to 100 ZIP codes.
Is the distance driving distance?
No. It measures a straight line between ZIP reference points. It can help shortlist nearby ZIPs, but does not check individual addresses or driving routes.
Can I do this from code?
Yes. This page is GET /postal/{code}/nearby, running from your browser. Same endpoint on every plan, one pooled request per call.
What about postal codes outside the US?
The API covers the countries listed on /postal where coordinates are available. This tool speaks ZIP, and the endpoint takes a country parameter for the rest.
I have a whole file of ZIPs.
Drop it on /bulk/zip. City, state, coordinates, and timezone land on every row.
