Postal codes were adopted in Ghana on 18 October 2017, following the launch of the National Digital Address System.[1][2] As a joint venture between Ghana Post (with support from the Government of Ghana]) and Vokacom Ltd as GhanaPost GPS, the Digital Address System assigned postal codes and unique addresses to every square in Ghana.[3][4]
Ghana's postal codes are alphanumeric. The first two characters form the postcode district - the first letter represents the region, and the second character represents the district in which the address is located.[5] The next three to five digits represent the postcode area and identify a more precise location within area.
Together, the postcode district and postcode area form the postal code.[6] For example, the Kwame Nkrumah Memorial Park & Mausoleum in Accra is located in postal code GA184, where GA represents the postcode district - G for the Greater Accra Region and A for the Accra Metropolitan District - and 184 represents the postcode area.
Examples of postal codes are GA107, EO1070, and N503074.
