Interoperability · without name matching

Codes should join data.
Not distort it.

Resolve Ghanaian region and district identifiers against an explicit namespace, effective date, dataset version, and source. Ambiguity stays visible.

Exact resolver

Ask with context.

A bare value like 03 is not enough. Select the code system first, then GhanaCodes resolves only within that namespace and effective version.

Crosswalk, do not guess

03→GAR

Both values resolve to geo:region:03. If a target namespace has multiple valid candidates, the API returns all candidates with an ambiguous status.
