List of 47 Counties in Kenya and Their Codes

The counties in Kenya and their codes define the country’s current administrative structure. Established under the 2010 Constitution, the counties replaced the former provinces, creating a devolved system that empowers local governance. Each county is governed by an elected governor and operates independently under the County Government Act. Turkana is the largest by landmass, while Mombasa is the smallest.
