Telephone numbers in Ghana
The telephone numbering plan of Ghana is administered by the National Communications Authority, which holds responsibility for telecommunications.
Since 1 May 2010, all fixed-line numbers and mobile telephone numbers have nine digits, comprising one digit for the area code and eight digits for the local directory number. It is customary to also include the trunk prefix 0 before the national telephone number in listings.

Mobile numbering plan
Due to the unreliability of fixed-line infrastructure in Ghana, mobile phones are more widely used. Competition among the various mobile carriers has spurred growth with a subscriber penetration rate of 98% in 2010. The poor call quality of mobile phones, however, means that more people hold more than one mobile phone, usually with two or more different carriers.The various mobile carriers in Ghana have each been assigned a network code.
