- Example
- +29051234

- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Saint Helena phone number is a short 5-digit number under the country code +290. One of the most remote inhabited islands on Earth, Saint Helena is a British Overseas Territory in the South Atlantic best known as Napoleon Bonaparte’s final place of exile after Waterloo in 1815 — he died there in 1821 — and it didn’t gain a commercial airport until 2017, having relied on a mail ship from South Africa until then.
How this validator works
Enter the number in national form (51234) or full international form (+29051234); this tool checks the 5-digit length and pattern against Saint Helena’s real numbering plan using Google’s libphonenumber, entirely in your browser. Saint Helena shares administration with Tristan da Cunha and Ascension Island but keeps its own numbering within the shared +290 code — Tristan da Cunha’s local numbers, though also +290, run just 4 digits rather than 5.
What a pass doesn’t tell you
A pass confirms the digits form a real Saint Helena number shape — it doesn’t confirm the SIM is active or the landline connected, a separate carrier-side question this tool doesn’t try to answer.
Scope: useful for catching a malformed or wrong-length entry before a Saint Helena number reaches a form — not a substitute for a real lookup service.

phone number FAQ
Why is Saint Helena associated with Napoleon Bonaparte?
After his final defeat at Waterloo in 1815, Napoleon was exiled by the British to Saint Helena, one of the most remote inhabited islands on Earth, specifically to prevent another escape. He lived there until his death in 1821, and his former residence remains a major historical site on the island today.
When did Saint Helena get an airport?
Not until 2017 — before that, the island was reachable only by a multi-day mail ship from South Africa, making it one of the last inhabited places on Earth to gain scheduled air access, decades after most comparably remote territories.
Does a valid check confirm a Saint Helena number is currently active?
No. It only confirms the 5 digits match a real numbering pattern under +290 — not that the SIM is active, which needs a carrier-side lookup this free tool doesn't perform.
