Frequently asked questions about Mexico ZIP Codes API

What data do I get for a zip code?

Given a 5-digit Mexican codigo_postal, the API returns its estado, municipio, and the full list of colonias for that code.

Can I search without knowing the full zip code?

Yes. You can search by partial code (e.g. 6641 returns all codes starting with those digits) with an optional limit, or do a reverse lookup by estado + municipio + optional colonia. Location search is accent- and case-insensitive.

Where does the data come from and how current is it?

Data is sourced from Correos de México (SEPOMEX) and updated weekly, covering all Mexican postal codes.
