Regulatory and Technical Notes

Geographic numbering in Cape Verde is managed by the National Communications Agency (ANAC). The 251 code is exclusively for fixed-line services, and numbers are allocated to the incumbent operator and other licensed fixed-line providers. As of recent years, there have been no overlay plans for this area code; the numbering capacity is sufficient for the island's population. However, with the growth of tourism and local businesses, it is advisable to verify the current numbering plan for any potential expansions.

For VoIP users, it is important to note that geographic numbers are tied to a physical location, but many providers allow registration with a Cape Verdean address. When dialing from a VoIP service, the same international format (+238 251 XXXX) applies.
