Administrative boundary CODs include:

1. Geographic boundaries in shapefile, geodatabase, and other formats, often including live geoservices. Some countries also have edge-matched administrative boundary variants. (See COD-AB-EM.)

2. Gazetteers of feature names and P-codes.

COD-AB datasets can be linked by database or GIS to COD-PS datasets, when available using the P-codes as a key.

Boundaries and gazetteers reflect the country’s specific administrative hierarchy.

COD-AB datasets are adopted by the country or regional Information Management Working Group as the standard.
