Area Code 235 – Cuanza Norte

Overview of Area Code 235 (Cuanza Norte, Angola)

Area code 235 is a geographic National Destination Code (NDC) assigned to the Cuanza Norte Province in Angola. It is used for fixed-line (PSTN) services within this administrative region, which is located in the northwestern part of the country. The province’s capital is N'dalatando, and the code also covers other municipalities such as Lucala, Golungo Alto, and Quiculungo. As with all Angolan geographic codes, 235 is part of the national numbering plan under the country’s country calling code +244.

Dialing Formats

When calling a fixed-line number in Cuanza Norte, the complete international format is +244 235 XXX XXX, where +244 is Angola’s country code, 235 is the area code, and the subscriber number typically consists of seven digits (though the total length may vary). For domestic calls made from within Angola but outside the 235 area, you must dial the trunk prefix 0 followed by the area code and subscriber number: 0 235 XXX XXX. For calls made from within the same area, local dialing may omit the area code, but it is recommended to use the full national format to avoid confusion, especially with mobile number portability.

Geographic Coverage and Administration

Cuanza Norte is one of Angola’s 18 provinces and is bordered by Malanje, Uíge, Bengo, and Cuanza Sul. The province is primarily agricultural, with significant coffee and maize production. The area code 235 is administered by Angola’s telecommunications regulator, the Instituto Angolano das Comunicações (INACOM), which oversees the allocation of numbering resources to licensed operators. Fixed-line services in this region are provided by the incumbent operator Angola Telecom, as well as other licensed fixed operators.

Caller Instructions

For international callers: Dial your country’s international access prefix (e.g., 00 or +), then 244 (Angola’s country code), followed by 235 and the subscriber number. Example: +244 235 123 456.

For domestic callers outside Cuanza Norte: Dial 0, then 235, then the subscriber number. Example: 0 235 123 456.

For local callers within Cuanza Norte: If your phone system supports local dialing, you may dial only the subscriber number. However, due to the increasing use of VoIP and mobile networks, it is advisable to always use the full national format to ensure successful routing.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for Cuanza Norte, meaning that 235 remains the sole geographic code for the province. However, with the growth of fixed-line services and the potential introduction of new operators, it is essential to verify the current dialing procedures with your service provider. Additionally, the Angolan numbering plan is undergoing modernization, and subscribers should be aware that number lengths and dialing rules may change. Always consult official sources for the most up-to-date information.
