This article lists Kenya County numbers from 1 to 47. County numbers help to codify the particular county so that it is easy to identify it and its assets for particular purposes. Kenya has 47 counties within its border. The Independent Electoral Commission of Kenya lists the diaspora as County Number 48.
Also, counties found in the same region for instance, western, follow each other in enumeration – so it is easy to tell whether the counties border each other.
An example in use of county numbers is the number plate of the county vehicles. For example, official vehicles for the county of Nairobi Governor’s office are codified 047. You can therefore tell which institution owns a vehicle by looking at the car number plate code and colour.
