St. Helena, a remote British Overseas Territory in the South Atlantic Ocean, is renowned for its dramatic volcanic terrain and historical significance as Napoleon’s place of exile. While its isolation has historically limited connectivity, modern telecommunications have evolved significantly, particularly with the arrival of the submarine cable Equiano in 2023. For international callers, understanding the country’s dialing protocol is essential for both personal and business communication. The territory uses the international calling code +290, which also serves the dependencies of Ascension Island and Tristan da Cunha. However, each island operates under separate numbering plans, and callers must be aware of these distinctions to avoid misdialing.

How to Dial St. Helena

Placing an international call to St. Helena requires a straightforward sequence. Begin with the international access prefix (commonly “00” in most countries, or “011” from North America), followed by the country code +290, and then the subscriber’s five-digit local number. St. Helena uses a closed numbering plan, meaning there are no separate area codes; the entire five-digit number must be dialed after the country code. For example, a call to a landline in Jamestown might be formatted as +290 2XXXX (where “2” is a typical prefix for fixed lines). Mobile numbers also follow the five-digit format, often beginning with “5” or “6”. It is crucial to omit any leading “0” that might appear in local listings, as St. Helena does not use trunk prefixes.

Area Codes and Numbering Context

Unlike larger countries with multiple area codes, St. Helena’s small population (approximately 4,000) allows for a simplified numbering scheme. The +290 country code is shared with Ascension Island and Tristan da Cunha, but each territory maintains its own allocation of five-digit numbers. For instance, Ascension Island numbers typically start with “6”, while St. Helena numbers often begin with “2” (fixed lines) or “5” (mobile). Tristan da Cunha, the most remote inhabited island, uses numbers starting with “8”. This structure means that callers must know the specific island they are trying to reach, as the same +290 code is used for all three. When dialing from abroad, you cannot simply rely on the country code alone; the first digit of the local number provides the necessary routing information.

Special Rules and Considerations

One of the most important rules when dialing St. Helena is to ensure you have the correct five-digit number. Directory assistance services are limited, and online directories may be outdated. Additionally, due to the territory’s reliance on satellite and submarine cable infrastructure, call quality can vary, though the Equiano cable has dramatically improved internet and voice services. For businesses, it is advisable to confirm numbers via official government or tourism websites before initiating calls. There are no special premium-rate numbers or emergency service variations; the standard emergency number is 999, as in the UK. When calling from the UK, the international prefix is “00”, so a call would be placed as 00 290 XXXXX. From the US and Canada, use “011 290 XXXXX”.

Traveler and Business Tips

For travelers visiting St. Helena, staying connected is easier than ever, but roaming charges can be high. It is recommended to purchase a local SIM card from Sure South Atlantic, the sole telecommunications provider, upon arrival. These SIMs offer affordable data plans and local call rates. For business professionals, scheduling calls requires attention to time zone differences—St. Helena operates on Greenwich Mean Time (GMT) year-round, with no daylight saving time. When making international calls to St. Helena, be mindful of the island’s working hours (typically 8:00 AM to 4:00 PM local time). For outgoing calls from St. Helena, the international prefix is “00”. Always double-check the number format with your contact, as numbers are occasionally listed with a leading “0” (e.g., 02XXXX), which should be dropped when dialing internationally. As the territory continues to develop its digital infrastructure, voice over IP (VoIP) services are becoming popular, but they require a stable internet connection, which is now available via fiber and 4G LTE.
