Ghana does not use zip codes. Instead, they use the postal code system, which was adopted on October 18, 2017, following the launch of the National Digital Address System. The postal codes are alphanumeric and are variable in length, ranging from five to seven characters. 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. The next three to five digits represent the postcode area and identify a more precise location within the area. If you need to fill out an online form that requires a zip code, you can use 00000 or other random numbers.
