Area Code 233 – Uige

Overview of Area Code 233 (Uíge, Angola)

Area code 233 is a geographic National Destination Code (NDC) assigned to the province of Uíge in the Republic of Angola. It is part of the Angolan national numbering plan, which adheres to the ITU-T E.164 recommendation. The code is used to route calls to fixed-line subscribers within the Uíge province, covering the provincial capital, also named Uíge, and its surrounding municipalities and rural areas.

Geographic Coverage and Administrative Jurisdiction

Uíge province is located in the northwest of Angola, bordering the Democratic Republic of the Congo to the north. The area code serves both the urban center of Uíge city and the broader province, which includes municipalities such as Negage, Quitexe, and Songo. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) infrastructure of the region, and its allocation is managed by the Angolan communications regulator, INACOM (Instituto Angolano das Comunicações).

Dialing Formats and Caller Instructions

To call a fixed-line number in Uíge from within Angola, subscribers must dial the trunk prefix 0, followed by the area code 233 and the subscriber's local number. The complete national format is: 0 233 XXX XXX (where X represents the local number digits, typically 7 digits in total for the subscriber portion). For example, a local number might be dialed as 0233 123 456.

For international callers, the Angolan country code +244 is used, followed by the area code without the leading zero, and then the subscriber number. The international format is: +244 233 XXX XXX. For instance, calling from abroad would require dialing +244 233 123 456.

It is important to note that Angola does not currently have overlay codes for geographic areas; each province retains its own distinct area code. Therefore, callers within Angola must always include the area code even when dialing from a mobile phone, as mobile numbers are non-geographic and use separate prefixes.

Practical Considerations for Callers

When placing a call to Uíge, ensure you have the correct number of digits. Fixed-line numbers in Angola typically consist of 9 digits in total, including the area code (excluding the trunk prefix). If you are unsure about the subscriber number length, verify with the recipient or a local directory. Calls to geographic numbers are generally charged at standard national or international rates, depending on the caller's location and service provider. For businesses or individuals frequently contacting Uíge, it is advisable to store numbers in international format (+244 233 ...) to avoid confusion when traveling or using VoIP services.
