Area Code 269 – St. Helena

Geographic Overview and Administrative Scope

The +290 269 prefix is the sole geographic National Destination Code (NDC) assigned to the island of St. Helena, a British Overseas Territory in the South Atlantic Ocean. This code covers the entire island, including the capital Jamestown and all smaller settlements such as Half Tree Hollow, Longwood, and Sandy Bay. Because St. Helena has a single NDC, the prefix does not denote a specific city or district; rather, it identifies any fixed-line subscriber on the island. The numbering plan is administered by the Communications Regulator of St. Helena, and the current allocation follows ITU-T E.164 recommendations.

Dialing Formats and Numbering Structure

St. Helena’s national significant number (NSN) is five digits in length, always beginning with the digit '2'. The complete international format for a fixed-line number is +290 269XX, where 'XX' represents the subscriber’s two-digit line number. For example, a typical number would be +290 26942. When dialing locally from another St. Helena fixed line, callers must include the full five-digit number, e.g., 26942. However, because the island also has a mobile network using the prefix 5, local callers must be careful to dial all five digits to ensure correct routing. For international callers, the sequence is: international access code (e.g., 00 or +), then 290, followed by the five-digit subscriber number. No trunk prefix (such as '0') is used when calling from abroad.

Caller Instructions and Overlay Considerations

There are no overlay codes or additional geographic prefixes on St. Helena; the +290 269 range is exclusively for fixed-line services. Calls from mobile phones on the island to fixed lines require the same five-digit dialing format. For callers outside St. Helena, it is essential to replace the leading '+' with the appropriate international exit code from their country. For instance, from the United States, one would dial 011 290 26942. From the United Kingdom, the sequence is 00 290 26942. The island’s small population and limited number of fixed lines mean that the 269 prefix is not further subdivided; all fixed-line subscribers share this code.

Technical and Regulatory Notes

St. Helena’s telecommunications infrastructure has evolved from traditional PSTN to include VoIP and mobile services, but the fixed-line network remains a critical component for businesses and government offices. The +290 269 prefix is not portable to mobile networks, as mobile numbers use the separate 5 range. When dialing from a VoIP service, users should ensure that their provider supports international dialing to +290. Because of the island’s remote location, call routing may involve satellite or submarine cable links, but the numbering plan remains stable. For accurate billing and routing, always verify the full five-digit number before placing a call.
