Telephone numbers in South Africa

Telephone numbers in South Africa are administered by the Independent Communications Authority of South Africa. On 16 January 2007, the country switched to a closed numbering plan. It became mandatory to dial the full nine-digit national telephone number. For calls within the country, this is prefixed by trunk code 0 (zero), which is often included in listings of the area code. Area codes within the system are generally organized geographically. Special services by Telkom have numbers with special formats.

When dialed from another country, the national number is prefixed with the appropriate international access code and the telephone country code 27.
