Area Code 236 – Cuanza Sul

Overview of Angola's +244 236 Geographic Code

The +244 236 country and area code combination is assigned to the Cuanza Sul province in Angola, a geographic region located south of the capital, Luanda. This code is part of Angola's national numbering plan, which follows the ITU-T E.164 recommendation. The 236 prefix functions as a National Destination Code (NDC) for fixed-line telephone services within the province. Administratively, Cuanza Sul is divided into municipalities, with Sumbe serving as the provincial capital. Other significant urban centers covered by this code include Porto Amboim, Gabela, and Quilenda.

Dialing Formats and Usage

To call a fixed-line number in Cuanza Sul from abroad, you must dial the international access prefix (e.g., 00 or + from most countries), followed by Angola's country code 244, then the area code 236 (without the leading trunk prefix), and finally the local subscriber number. For example, if the local number is 123 456, you would dial +244 236 123 456 from an international line. Within Angola, callers must use the national trunk prefix '0' before the area code. Therefore, a domestic call to the same number would be dialed as 0 236 123 456. It is essential to note that the trunk prefix is not included when dialing from outside the country.

Geographic Coverage and Numbering

The 236 code covers all fixed-line subscribers in Cuanza Sul, including both residential and business lines. The province's telecommunications infrastructure is primarily based on copper and fiber-optic networks, with increasing VoIP adoption. As of the latest numbering plan updates, there are no overlay codes or area code splits planned for this region, meaning that the 236 code remains the sole geographic identifier for fixed-line services in Cuanza Sul. Local numbers typically consist of seven digits, but the total length of a national significant number (NSN) is nine digits, including the leading '0' for domestic dialing.

Caller Instructions

For international callers, always replace the '+' with the appropriate international access code from your country (e.g., 011 from the US, 00 from most European countries). Ensure you omit any leading '0' from the area code when dialing internationally. For local callers within Cuanza Sul, it is still necessary to dial the full national format, including the trunk prefix and area code, as local number portability may not guarantee that the call remains within the same exchange. Always verify the number with the recipient to avoid misdialing.
