Area Code 183 – Khartoum

Overview of Area Code +249 183

Area code 183 is a geographic National Destination Code (NDC) assigned to the city of Khartoum, the capital and largest metropolis of the Republic of Sudan. Under the ITU-T E.164 international numbering plan, the full country calling code for Sudan is +249. When dialing a landline in Khartoum from abroad, the international format is +249 183 XXX XXX (or +249183XXXXXX when written as a continuous string). Within Sudan, callers must dial the trunk prefix 0 before the area code, resulting in the national format 0 183 XXX XXX.

Geographic Coverage and Administrative Significance

The 183 code covers the Khartoum locality, which encompasses the tri-city capital area formed by Khartoum, Omdurman, and Khartoum North (Bahri). These cities are separated by the Blue and White Nile rivers and together constitute the political, economic, and cultural heart of Sudan. As the seat of the national government, foreign embassies, and major financial institutions, Khartoum hosts a dense concentration of fixed-line subscribers, including government ministries, corporate headquarters, and residential users. The 183 code is one of several geographic codes used in the greater Khartoum metropolitan area; other codes may be allocated for different exchanges or districts within the capital region.

Dialing Procedures and Numbering Details

Sudanese fixed-line numbers using the 183 code typically consist of seven digits after the NDC, making the complete national significant number (NSN) nine digits (including the leading 0). For example, a local number might appear as 0 183 456 789 in national format and +249 183 456 789 in international format. When calling from a mobile phone within Sudan, the same trunk prefix and area code are required. However, if you are dialing from a landline in the same local area, you may be able to omit the area code and dial only the seven-digit subscriber number, depending on the operator's local dialing plan. Overlay codes are not currently in use for Khartoum, so the 183 code remains the primary fixed-line identifier for the city.

Caller Instructions and Practical Considerations

For international callers, always replace the leading 0 of the national prefix with the country code +249. For example, to call a Khartoum number 456 789 from the United States, you would dial 011 249 183 456 789 (or +249 183 456 789 from a mobile phone). Local callers should use 0 183 456 789 from any other region in Sudan. Be aware that network congestion, especially during peak business hours, may affect call quality. Also, note that some businesses may have migrated to VoIP or mobile services, so always confirm the correct number format with the recipient if you encounter issues.
