^[+]?[0-9 ()\-]{6,}$An Ascension Island phone number is a short 5-digit number under the country code +247 — one of the shortest numbering plans this tool covers. The island itself is a remote volcanic outcrop in the South Atlantic, roughly 1,600 km from the African coast, with no indigenous or hereditary population: everyone present is there on a work contract, largely tied to the joint UK–US Wideawake Airfield or the BBC World Service relay station that has broadcast from the island since the 1960s.
How this validator works
Enter the number in national form (40123) or full international form (+24740123); this tool checks the digit count and pattern against Ascension’s real numbering plan using Google’s libphonenumber, entirely client-side. Because the island shares administration with Saint Helena and Tristan da Cunha but keeps a separate +247 code from their shared +290, it’s easy to assume all three use one numbering plan — they don’t.
What a pass doesn’t tell you
A pass confirms the digits form a real Ascension Island number shape — it doesn’t confirm a specific line is connected or reachable, a question only a carrier lookup can answer.
Scope: useful for catching a malformed digit before an Ascension number reaches a form — not a substitute for a real lookup service.

phone number FAQ
Is Ascension Island part of the UK the way England or Scotland is?
No. Ascension is a British Overseas Territory, administered together with Saint Helena and Tristan da Cunha as one territory, but it isn't part of the United Kingdom itself. There's no hereditary population — everyone living there does so under a work permit tied to a job on the island.
Why does Ascension Island use +247 instead of the UK's +44?
Because it's numbered as its own territory rather than folded into the UK plan the way Guernsey or Jersey are. +247 is assigned specifically to Ascension, separate from Saint Helena's own +290 code despite the shared administration.
Does a valid check confirm an Ascension number is currently active?
No. It only confirms the 5 digits match a real Ascension Island numbering pattern under +247 — not that the line is connected, which needs a carrier-side lookup this free tool doesn't perform.
