Sending SMS to American Samoa

American Samoa is on the North American Numbering Plan as +1 684, then seven digits. A US territory in the South Pacific, roughly halfway between Hawaii and New Zealand, it sits on the same plan as the mainland but a very long way from it. English and Samoan are both Latin script, so messages stay in GSM-7.

+1684 — +1684 followed by the national number

From abroad, replace your exit code with +, then 1684, then the national number — dropping the national trunk prefix if the country uses one (a leading 0 in most, though not in the +1 numbering plan). Store numbers in E.164 (+1684…) and they work from any country and any API.
