Whether shipping a high-value package to a customer or a holiday card to a loved one, sending documents and packages from one place to another necessitates using valid address data for prompt and accurate delivery. The combinations of numbers (and sometimes letters) in a postal code form a specific identification code that allocates delivery points to a particular location, whether a package is shipped within a state, across a given country, or to another country entirely across the world.
It’s important to note that the format and implementation of these codes vary depending on the specific geographical location they’re tied to, so postal codes will likely differ from country to country.
A zip code refers to a type of postal code and is used primarily in the United States and the Philippines. The postal code, however, is typically utilized by the rest of the countries scattered throughout the world. Unlike postal codes, which can contain a mixture of numbers and letters, zip codes only contain numeric values.
Several countries adopted postal codes at different times. Other countries, like Ukraine, adopted postal codes earlier, using them from 1932 until 1939. Germany followed in 1941 with two- and three-digit codes, while Singapore, Argentina, the United Kingdom, and Switzerland implemented their systems between 1950 and 1964. The United States introduced the five-digit ZIP code under the USPS, later enhanced in 1983 with the ZIP+4 code to specify more precise locations.

Ghana's Postal Codes
Ghana's postal codes are alphanumeric. Each postal code is divided into two parts: the postcode district and postcode area. The postal codes are alphanumeric and are variable in length, ranging from five to seven characters.
The simplest address format, recognized by the national post, Ghana Post is:
- Recipient Name
- Street Name
- Digital Address
- Area
- Region
Here is an example of postal code:
As of December 2017, the list of frequently asked questions does not state if/where the algorithm for generating the postcodes is publicly available, or how the algorithm is licensed. It is also not stated if/how bulk conversion of coordinates into postcodes is possible. This suggests that, at least at present, the algorithm is likely proprietary.
This is a feature also of other postcode systems, although open postcode systems are also available. Open postcode-like systems include the Open Location Code.

GhCode: A Postcode System for Ghana
Urban GeoVizual Solutions (UGS), a GIS and Urban Planning Consultancy based in Accra, is launching GhCode. The birth of a postcode system in Ghana is called GhCode.
GhCode is a postcode system, which has been developed to suit the uniqueness, form, dynamics and complexities of Ghana’s cities and towns.
Potential Benefits of GhCode
- The ability of the postal service of Ghana and other courier services to undertake door to door delivery of posts, whilst at the same time providing employment to solve some of the high rates of unemployment in Ghana.
- According to Francis Asenso-Boakye, a development policy analyst: the GhCode is a major breakthrough in addressing the problem of asymmetric information associated with informal economies and the credit market such as banks and micro finance institutions.
The GhCode has received positive reactions from some Ghanaians.
According to Magnus Lincoln Quarshie (President elect of Ghana Institution of Engineers); “…this can create nearly 1500 to 2000 jobs in the postal service alone. Postmen on bikes, foot and motorbikes doing postal deliveries.
Dr. Ohene Sarfo (a Development Consultant) also said; "This GhCode system is being proposed at a very important time in the life of this country when we need to resolve once and for all the issue of household and property address age.
