- 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,}$An American Samoa phone number is a 10-digit NANP number under area code 684, written as +1 684 733 1234 internationally. Centered on the capital Pago Pago, American Samoa is an unincorporated US territory in the South Pacific — geographically and culturally distinct from independent Samoa (dial code +685) just across the international date line, despite the shared name and Polynesian heritage.
How this validator works
Enter the number in national form (6847331234) or full international form (+16847331234); this tool checks the digit count and confirms the 684 area code sits within American Samoa’s assigned NANP block, using Google’s libphonenumber entirely client-side. Since NANP covers many countries under one +1 code, mixing up American Samoa’s 684 with a neighboring Pacific territory’s area code is a common data-entry slip this check catches.
What a pass doesn’t tell you
A pass confirms the digits form a real American-Samoa-area-code NANP number — 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: catches a mistyped area code or digit before an American Samoa number reaches a form — not a substitute for a real lookup service.

phone number FAQ
Are American Samoans US citizens?
Not automatically. People born in American Samoa are US nationals rather than US citizens at birth — an unusual status among US territories, which stems from the territory never having been incorporated the way Puerto Rico or Guam eventually were. The +1 684 numbering plan, though, works exactly like any other NANP territory.
Why does American Samoa share the +1 code with the mainland US?
Because it's part of the North American Numbering Plan (NANP) as a US territory, with its own dedicated 684 area code. Calls from the mainland reach it like a domestic long-distance call rather than crossing an international boundary.
Does a valid check confirm an American Samoa number is currently active?
No. It only confirms the 10 digits match a real 684-area-code NANP number — not that the specific line is connected, which needs a carrier-side lookup this free tool doesn't perform.
