API

Free Mexico Zip Codes & Geocoding API

Overview

Postali API delivers RESTful access to comprehensive Mexico zip code data, including city, state, municipality, geographic coordinates (latitude/longitude), and address validation capabilities. Key endpoints allow fetching zip code details by code, reverse geocoding (coordinates to zip code), and filtering locations by state or municipality. Responses are JSON-formatted, ideal for e-commerce shipping address auto-completion, logistics route optimization, location-based app features, and address verification for Mexico-based services.
