Number plates for diplomatic vehicles in Kenya have distinct red colour with letters CD specific numbers assigned to a country.

The number plates were assigned to the countries with embassies in Kenya in the order of when they recognized Kenya’s independence.

The first figures are the code for the diplomat's country, the CD shows it is for a Chartered Diplomat, and the next figures show which embassy it is allocated to depending on the rank of the car owner then, at the end is K which means the embassy is based in Kenya.

For instance, diplomatic registration number 1 CD 12 K, where 1 is the code for the diplomatic country.

CD means it is for a Chartered Diplomat, while 12 represents the rank of the car owner. K indicates that the embassy is located in Kenya. 

The unique identification codes are meant to help law enforcement officers keep track of the country's diplomatic cars and enable the National Transport and Safety Authority (NTSA) to effectively perform its mandate.

To enhance service delivery, Former Interior Cabinet Secretary Fred Matiang'i opened GoK-UN Service Center in Gigiri, Nairobi, to allow diplomats to access several services including those relating to NTSA.

With the opening of the center, envoys will acquire all services within 12 hours.

It is however worth to note that vehicles bearing Diplomatic number plates are not exempted from local traffic laws.Incase of a breach cases are handled by the Diplomatic Police Unit.
