Kakamega Postal Codes – Official Post Offices & Areas

Kakamega County is in Western Kenya and has a network of post offices serving towns and rural areas, including Kakamega Town, Lugari, Malava and Mumias. Posta uses postal codes to identify individual post offices and help route mail. The county has 12 administrative constituencies, but a constituency does not necessarily have one code for every address within it.

Kakamega’s postal codes have deep historical roots. The area was historically associated with North Kavirondo and is part of the Luhya ancestral homeland. British authorities established an administrative and defensive post in Kakamega in 1903, and by 1920 the town had become a district headquarters. The Kakamega goldfield was discovered at the end of 1930, leading to a gold rush in the early 1930s. Kakamega’s post-office codes use the 5-series regional numbering.

What Are Kakamega Postal Codes?

Kakamega County uses the postal region prefix 5, which identifies it as part of the Western region postal area managed by the Postal Corporation of Kenya, popularly known as Posta Kenya. This differs from Nairobi’s 00 prefix, Mombasa’s 80 prefix, or Eldoret’s 30 prefix. The format follows Kenya’s postal code structure, which is usually a standard five-digit structure: the first two digits (50) represent the broader region, while the final three digits pinpoint the specific post office or delivery zone.

For example, 50100 is the main Kakamega G.P.O. code, which can be broken down as:

5 = Western region (Kakamega County)
0 = Regional subdivision
100 = Kakamega Town GPO (General Post Office)
