02The basics

What is the country code for Saint Helena?

Marooned in the South Atlantic between Africa and South America, Saint Helena is a British Overseas Territory best known as Napoleon's final place of exile — and it remains hard to reach in every sense.

Its country code is +290, and the numbers behind it are short by design, historically a flat 5-digit plan that suits a population of a few thousand. Add +290 after your exit code and the island is on the line.

Code +290 was assigned to Saint Helena by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.

+29000290011 29000 290

All four mean the same thing — they connect your call to Saint Helena.

03Dialing format

How to call Saint Helena from anywhere

It's about as short a string as international dialing gets: your exit code, +290, then the island's local number. No trunk prefix sits in the way, so there's nothing to strip out.

04Number format

Saint Helena phone number format explained

With only a few thousand lines to assign, Saint Helena never needed a long plan — historically a flat 5-digit national number with no area codes at all. Fixed and mobile numbers live side by side in that short range, told apart by their leading digits rather than by any geography.

Landline

Format +290 XXXXX. Fixed lines come from Sure South Atlantic, the island's sole provider.

Mobile

Format +290 XXXXX. Mobile service (2G/4G) arrived relatively recently via Sure, and mobile numbers draw from the same short national plan.

06Mobile networks

Saint Helena mobile network prefixes

The prefix after +290 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.

SS

Sure South Atlantic (Sure SH)

+290 the sole provider of landline, mobile (2G/4G), broadband and international connectivity on the island. Mobile numbers fall within the island's short national plan.

07Time zone

Saint Helena time zone

Despite sitting far out in the South Atlantic, Saint Helena keeps Greenwich Mean Time (GMT), UTC+0, all year. There's no daylight saving here, so the island holds steady on UTC+0 while London springs forward and back around it.

Midday to late afternoon in Jamestown (12:00–16:00 GMT) lines up neatly with UK afternoons in winter — though British Summer Time pulls London an hour ahead of the island — and reaches the US East Coast in its morning.

Common mistakes when calling Saint Helena

Almost every failed international call is a formatting issue, not a network issue.

Reaching for +247 instead of +290

Ascension Island, Saint Helena's near neighbor in the territory, has its own separate code. +290 covers Saint Helena and Tristan da Cunha; Ascension is +247. Two specks in the same ocean, two different numbers.

Expecting a long string

the island's plan is short, historically just 5 digits, so don't assume you've lost part of it.

Searching for an area code

there isn't one; the whole island shares a single short plan.

Forgetting the island holds GMT year-round

during British Summer Time the gap to the UK opens by an hour.

Assuming a choice of carriers

Sure is the only operator on the island.

Tips to reduce the cost of calling Saint Helena

Lean on VoIP/SIP wherever you can

calls riding the island's long-haul connectivity have always carried a premium.

Hold a +290 virtual number so islanders reach you at a local rate instead of an international one.

Cluster calls into business hours to sidestep costlier off-peak handling.

For any real volume, route through a wholesale carrier rather than retail minutes.

11For business

Why businesses get a Saint Helena virtual number

Getting a foothold on one of the world's remotest islands once meant shipping in equipment and people. A +290 virtual number puts you on island lines without any of that — no hardware, no presence, no voyage.

Higher answer rates

Higher answer rates — on a small island, a recognizable +290 number gets answered where an overseas one doesn't.

Lower trust friction

Lower trust friction — a local code reads as part of the community, not an outside cold call.

Cheaper inbound

Cheaper inbound — islanders reach you at local rates, not the cost of an international leg.

Centralized routing

Centralized routing — pull every +290 call back to your team, wherever in the world it sits.

Faster expansion

Faster expansion — serve the territory without an office or a shipment of gear.

Real PSTN presence

Real PSTN presence — a genuine Saint Helena number, not a forwarding workaround.
