History
Creation: American Samoa was the last US territory to join the North American Numbering Plan, on October 2, 2004, taking area code 684 — the same digits as its previous ITU country code, +684. Before the change, a call from the US mainland was dialed as an international call (011 684); joining the plan made it a domestic +1 call.
Mnemonics: The digits 684 map to letter combinations on the standard telephone keypad, yielding 27 possible three-letter mnemonics. Telecom regulators sometimes pick one of these as a marketing handle (e.g. ‘BHA’ for The Bahamas, ‘TNT’ for Trinidad and Tobago).

How to call American Samoa
No 011 prefix needed — American Samoa is part of the NANP, so calls dial like a domestic North American number. Long-distance and roaming charges still apply.
Use your country's international access code (00 in most of Europe, 0011 in Australia), then 1, the 684 area code, and the local number.
Domestic calls use seven digits — no area code prefix needed.
