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.
