Mexico Postal Codes, Lat/Long, Time Zones Database

Mexico Latitude Longitude Our enterprise-grade Mexican Postal Codes database with Latitude, Longitude, and Time Zones has been in the making for the past 20 years. As better mapping techniques became available, we have utilized them to provide an extremely accurate and clean product. We standardize the data to ensure consistency in spelling, casing, and to have uniform naming conventions. This database is for companies located in and outside of Mexico. There are 140,000+ records made up of 32,000 unique Mexico Postal Codes. Each postal code may cover multiple towns or neighborhoods. This database is updated regularly.

Diacritics (accented characters as in México)

This data includes three Character Sets: UTF-8 (commonly used), ISO‐8859‐1 (aka ISO Latin‐1), and ASCII for legacy systems that won’t accept accented characters. All are currently included as part of the download.
