Communications Authority of Kenya (CA) unveiled a telecommunications numbering and addressing scheme in 2002. The scheme aims to ensure stability and steady availability of adequate numbers for end users and for the overall growth of communication services in Kenya. The introduction of the new numbering plan was also necessitated by the market liberalization of the communication services in Kenya, which had resulted in creating a huge demand on the telecommunications numbering resources from the unprecedented growth of communications services in the country.

In view of the above, efficient management and administration of numbering resources takes centre stage.

  • Mobile Number Portability

    The Authority, on 7th October 2010, issued the Procedures and Guidelines for the Provision of Mobile Number Portability (MNP) Services in Kenya (PDF). These procedures and guidelines have been developed in consultation with mobile operators and the MNP services provider and shall form part of the Operators and Service Provider’s Licenses.

    The procedures and guidelines specify the different stages of the Mobile Number Portability process from the point when a subscriber requests to transfer or port a number from their current Mobile Service Provider (Donor operator) to another Mobile Service Provider (Recipient Operator), to the point when the subscriber has an active account on the recipient operator and the account on the donor operator has been closed and all other operators have been informed of the number porting.
