What are the Postal Codes of Mombasa?
Mombasa’s postal code is 80100, and, like all counties in Kenya, it is provided and managed by the Postal Corporation of Kenya (PCK). The 80100 is assigned explicitly to the Mombasa General Post Office to serve all postal offices in the county. However, Mombasa itself is divided into six sub-counties, each with its wards that can have their own postal code structure.
Mombasa Sub counties are as follows:
- Mvita
- Nyali
- Changamwe
- Jomvu
- Kisauni
- Likoni
The county’s postal codes—all beginning with the digit “8”—follow Kenya’s five-digit standardized system, where the first digit represents the coastal region, the next two digits indicate distribution centers, and the final two specify delivery offices.
