📍 Geographic Location of Cabinda

Geographic Overview

The +244 231 area code is the geographic National Destination Code (NDC) assigned to the Cabinda Province, an exclave of Angola located north of the Congo River, bordered by the Democratic Republic of the Congo and the Republic of the Congo. The province is administered separately from mainland Angola, and its primary city, Cabinda City, serves as the provincial capital and main economic hub. This area code is used for fixed-line (PSTN) services within the province, covering both residential and business lines.

Dialing Formats

When calling a fixed line in Cabinda from within Angola, you must dial the trunk prefix '0' followed by the area code and the subscriber number. The national significant number (NSN) for geographic numbers in Angola is 9 digits, including the leading '2' of the area code. Thus, the format is:

  • National (within Angola): 0 231 XXX XXX
  • International (from abroad): +244 231 XXX XXX

For example, a local number in Cabinda might be 231 456 789. To call it from Luanda, you would dial 0231 456 789. From outside Angola, you would dial +244 231 456 789.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan, Angola does not have overlay codes for geographic areas; each province retains a unique area code. The Cabinda code 231 is distinct from other Angolan provinces, such as Luanda (222) or Benguela (272). The numbering plan is closed, meaning the full national number must be dialed even for local calls within the same area code.

Caller Instructions

For callers within Angola, always include the trunk prefix '0' before the area code, even when dialing from a mobile phone. For international callers, replace the '0' with the Angola country code +244. Ensure you have the correct international exit code for your country (e.g., 00 from most European countries, 011 from the US/Canada) before dialing +244.

Cabinda's geographic isolation means that international calls to this region are routed via Angola's international gateway, and call quality is generally reliable. For businesses operating in Cabinda, it is essential to display both national and international formats on websites and marketing materials to facilitate communication from global clients.
