Ghana uses a nationwide alphanumeric postal code system called GhanaPostGPS, assigning codes to every location. Each code begins with two letters: the first for the region and the second for the district, followed by digits identifying specific grid areas. Below is a complete list of postal code prefixes for all regions with capitals and code ranges.

Ghana’s Postal Code Framework
Ghana’s postal codes were introduced with the GhanaPostGPS digital address system, assigning unique alphanumeric codes to every location in the country. The first two characters in a postal code identify the postcode district: the first letter signifies the region and the second letter or number indicates the district within that region.
These two characters combined form a prefix used here as a range that applies to all unique addresses within that district area. The remaining characters in a full code identify the precise grid location down to a small square of land. This structured system supports accurate mail routing, logistics, e‑commerce deliveries, emergency services, and formal addressing where traditional street names and numbering may be inconsistent.
For example, in Accra codes begin with “GA”, while Kumasi district codes begin with “AK”; each prefix corresponds to a geographic sector within the wider regional scheme.
