Overview

The Administrative Divisions DB API provides a structured list of all administrative divisions (states, provinces, regions, cities) for countries around the world. It requires no API key and returns simple JSON, making it easy to populate dropdown menus or validate location data in forms. This is ideal for any app that needs consistent, structured geographic data by country.

💡

Beginner Tip

Use ISO 3166-1 alpha-2 country codes (e.g., US, GB, JP) as your query parameter. The response data is cached so responses are nearly instant.

Common Errors & Troubleshooting

404 Not Found The country code provided does not match any available dataset file.
✓ Verify you are using the correct ISO 3166-1 alpha-2 code (2 uppercase letters). Check the repository README for supported countries.
Unexpected data structure The response schema may vary slightly between countries based on available division levels.
✓ Always check for the existence of nested fields before accessing them, as not all countries have the same administrative hierarchy.
Stale or outdated data The dataset is a static file in a GitHub repository and may not reflect very recent geopolitical changes.
✓ Check the repository's last commit date to assess data freshness. For critical applications, verify key entries against an official source.
