Mexico Address Validation,
Verification, and Autocomplete

You can explore all our address validation solutions in one place, including the Master address list, Address validation service, International address verification, USPS address verification tool, Bulk address validation, and Address autocomplete.

In Mexico, a valid address must match the country’s postal formatting rules. Verify that the postal code (Código postal) follows the 99999 format; it appears after locality; the street name comes before the house number. Include the Colonia (suburb/neighbourhood) where applicable. The standard Mexican address structure is: Street name, house number, locality, municipality.

Mexico uses the postal code format 99999. Locally, postal codes are referred to as “Código postal.” The postal code structure is 5-digit numeric: first 2 = state (32 states), remaining 3 = hierarchical sub-levels. Example address: Fernández de Lizardi 15, Palo Revuelto, 62920, Tepalcingo, Morelos. Postal codes are administered by Correos de México.

A properly formatted Mexican address follows this structure: Street name, house number, locality, municipality. In Mexico, the street name precedes the house number, and the postal code is placed after locality. A distinctive address element is the Colonia (suburb/neighbourhood). Example: Fernández de Lizardi 15, Palo Revuelto, 62920, Tepalcingo, Morelos.

Address validation checks format and completeness — whether an address is properly structured and meets postal standards. Address verification goes further by confirming the address exists and is linked to a real recipient. For example, validating a Mexican address means checking that the postal code (Código postal) follows the 99999 format and appears after locality. Verifying it means confirming that a real recipient lives or operates at that specific address. Most businesses benefit from both: validation broadly for data quality, and verification for higher-risk situations like compliance or fraud prevention.

Bulk validating addresses in Mexico means checking large volumes of records against the 99999 postal code format and 156,230 possible localities. API-based services process addresses one at a time, which introduces per-call costs, rate limits, and latency at scale. A self-hosted reference database lets you validate Mexican addresses locally with no API calls, no per-record fees, and no dependency on third-party uptime. GeoPostcodes provides 32,019 postal codes for Mexico, available as a downloadable dataset for direct integration into your validation pipeline.

Mexico has 32,019 postal codes (Código postal), covering 156,230 localities across 3,183 administrative regions. Postal codes follow the 99999 format. They are administered by Correos de México. GeoPostcodes maintains this dataset with regular updates as postal codes are added, merged, or retired.

Postal codes in Mexico are not static — Correos de México periodically adds, merges, and retires codes as populations shift and administrative boundaries are redrawn. With 32,019 active postal codes across 156,230 localities, even small changes can affect address validation accuracy. Businesses that rely on Mexican address data should use a regularly updated reference database rather than a one-time export to avoid mismatches over time.
