Area Code 281 – São Filipe, Fogo

Geographic Overview

The area code 281 is a geographic National Destination Code (NDC) assigned to the municipality of São Filipe, located on the island of Fogo in Cape Verde. Fogo is one of the Sotavento islands, known for its active volcano, Pico do Fogo, and its wine-producing regions. São Filipe serves as the administrative capital and main urban center of the island, hosting the local government, commercial activities, and the island's primary port.

Dialing Formats

When calling a landline in São Filipe from abroad, you must use the international format: +238 281 XXX, where +238 is the country calling code for Cape Verde, 281 is the area code, and XXX represents the subscriber's local number (typically 3 digits). From within Cape Verde, you would dial 281 XXX (omitting the international access code and country code). For local calls within the same area code, you may only need to dial the subscriber number, but it is always safe to include the area code.

Coverage and Administration

The 281 prefix covers the entire municipality of São Filipe, including the city itself and surrounding rural communities. It is administered by the national telecommunications regulator, Agência Nacional de Comunicações (ANAC), and is assigned to the incumbent operator, Cabo Verde Telecom (CVT), which provides fixed-line PSTN services. As a geographic number, it is tied to a physical location, and the number is not portable to other islands or to mobile networks.

Caller Instructions

• International callers: Dial your country's international access code (e.g., 00 or +), then 238, then 281, followed by the subscriber's 3-digit number. Example: +238 281 456.
• Domestic callers from other regions: Dial 281 followed by the subscriber number. Example: 281 456.
• Local callers within São Filipe: You can often dial just the 3-digit subscriber number, but using the full area code is recommended for clarity.

Technical Considerations

Geographic numbers in Cape Verde are allocated according to the national numbering plan, which follows ITU-T E.164 recommendations. The total length of a Cape Verdean national significant number is 7 digits, including the NDC. For São Filipe, the NDC is 281, leaving 3 digits for the subscriber line. This structure allows for up to 1,000 unique numbers per exchange. As Cape Verde continues to modernize its telecom infrastructure, these fixed-line numbers are increasingly used for VoIP and fiber-optic services, but the geographic significance remains for emergency services and number portability regulations.
