Until 1999, Kenya shared its telephone numbering plan with Tanzania and Uganda, meaning that in order to make calls between the three countries, subscribers needed only dial the area code and number, a legacy of the East African Post and Telecommunications Corporation (EAPTC) which was dissolved in 1977. As a result of the reorganisation of Tanzania's numbering plan in that year, direct dialling was discontinued, although calls between the three countries do not require international dialling, only a special three-digit code.

Land line phone numbers in Kenya follow the format Area Code + Phone Number. To dial a number within an Area and/or City, only the Phone Number needs to be dialed. When dialing from a different Area/City, the telephone number is dialed in the format 0 + Area Code + Phone Number. When dialing from overseas, the 0 is omitted.

In Kenya exists 4 mobile network operators (MNO): Safaricom, Airtel (former Zain / Celtel), Essar Telecom Kenya (yu mobile) and Telkom Kenya (Orange).The Communications Commission of Kenya (CCK) has assigned several Area Codes to each operator. All mobile Area Codes starts with the digit 7. Please note: Since April 2011 Mobile number portability (MNP) is implemented in Kenya. The phone number can be ported by the customer to another operator.
