State (Country Subdivision) Codes
The API uses ISO 3166-2 subdivision codes (without country code) for the "state" field in our API requests and responses. This page clarifies edge cases and exceptions to that rule.
In several countries where there are several levels of subdivisions the API may support some but not all of them.
