Time zone by ZIP code
Find the time zone and current local time for a ZIP code.
A ZIP can cross time-zone boundaries.
Use it in your app
GET /postal/33139?country=US
The reference time zone is returned when known, so this page is one /postal call from your browser. Same endpoint on every plan, one pooled request per lookup.
QUESTIONS
- Does it handle daylight saving?
- Yes. The answer is the IANA timezone for the ZIP, and the clock shown follows its current daylight rules automatically.
- Can one ZIP span two time zones?
- Some ZIP codes cross time-zone boundaries. This is one zone for the ZIP; use coordinates to check a specific location.
- Can I do this from code?
- Yes. GET /postal/{code}?country=US returns the reference time zone, city, state, county, and coordinates where known. One pooled request.
- What about coordinates instead of a ZIP?
- The Time API accepts latitude and longitude to check a particular location. Location accuracy matters near a time-zone boundary.
