Telephone numbers in South Sudan

South Sudan uses a two digit mobile code along with a seven digit phone number. For international calls, South Sudan has been assigned the +211 code by the International Telecommunication Union.

Before the secession in 2011, the area, later to be known as South Sudan, used Sudan's country-level calling code. After its secession as an independent state on 9 July 2011, South Sudan continued to use the country-level calling code of Sudan +249 until 1 October 2011. The United Nations recognized South Sudan on 14 July 2011, and in so the United Nations suggested the country-level calling code to become active by 16 July 2011. The calling code went "live" on 1 October 2011.

Service Provider codes
Each telephone service provider has a two-digit identifier. The first digit is 1 for fixed services, including wireline and fixed wireless, or 9 for GSM mobile services.

National calls
Calls taking place inside of South Sudan have a simple format of mm nnn nnnn (where mm represents the mobile code and nnn nnnn represents the local number). An ITU is not required for national calls. For example, a person in South Sudan contacting another person in the same country with a mobile code of 55 and a local number of 555-5555 would have a telephone number of 55 555 5555.

Inbound
Calls from outside South Sudan require a different dialing format to be used. International call prefixes, area codes, and phone numbers may vary. An inbound call has the format of +211 mm nnn nnnn (where mm represents the mobile code, and nnn nnnn represents the local number). The + represents the international call prefix used by the country where the call originates: for example, the United States and Canada use 011, and most other countries use 00. So for example, if someone from tried to call to the number 55-555-5555 in South Sudan from the United States, then one would use 011 211 55 555 5555.
