Area codes and dialing in American Samoa
American Samoa is one of the few US states still covered by a single area code, 684. Because there's no overlap, many local calls can still be completed with seven digits, although dialing the full 10-digit number always works and is the safer habit. 684 serves Pago Pago and the rest of the state, all in the Samoa Time zone.
If American Samoa ever exhausts its supply of numbers, regulators would almost certainly add an overlay rather than split the state — the modern approach that lets everyone keep their existing number. For now, every American Samoa number shares the 684 code. Learn the background in how area codes work.
