Mexico Administrative Divisions

What is the hierarchy of administrative divisions in Mexico?

Mexico operates on a two-level administrative system, starting with 32 federal entities (31 states and Mexico City) at the top level, followed by municipalities as the smallest official administrative units. Cities exist within municipalities but are not administrative units themselves.

Here’s a breakdown of the hierarchy:

1. States and Mexico City: Mexico is divided into 31 states and 1 federal entity, Mexico City.

2. Municipalities: Each state and Mexico City is subdivided into municipalities, which are the smallest official administrative units.

Why is building an Administrative Divisions Database complex?

The complexity arises from inconsistent global standards, frequent boundary changes, non-uniform naming conventions (e.g., “suburb” in Australia vs. “county” in the US), and variations in administrative levels across countries. Integrating and harmonizing data from multiple sources requires advanced normalization, versioning, and geospatial validation techniques.

How does GeoPostcodes solve the problem for you?

Our standardized database overcomes the complexity of different administrative division
systems worldwide. Our database follows a unified structure that you can integrate
seamlessly into your system or platform of choice without needing to become an expert in
each country’s unique administrative hierarchy.

Our location dataset for Mexico

Mexico ZIP Codes

Mexico uses a “Código postal” system, which is a five-digit numeric format, like 99999, with no letters or separators. This is similar to US ZIP codes, which are also five digits and purely numeric. According to the GeoPostcodes world postal code database, Mexico has 32,019 postal codes covering 3,183 regions and 156,230 towns.

Mexico ZIP & Administrative boundaries

Mexico administrative landscape often follows inconsistent regional models and irregular public sources, making it difficult to maintain reliable boundaries. Our standardized postal and administrative boundary data resolves these gaps to ensure complete, coherent geographic coverage.

Mexico Address Format

Address conventions differ by country, leading to frequent validation errors and incomplete entries. Our dataset applies Mexico correct address format to ensure clean inputs, smoother validation, and reduced delivery mistakes.
