American Samoa joined the North American Numbering Plan in 2004, so it shares country code 1 and is scoped by area code 684 alone. From the US mainland it is 1 684 and a local number, though it is often billed as international. There is no trunk prefix; calls beyond the NANP start with 011.

Ten NANP digits: area code 684 plus a seven-digit local number; islanders dial just the seven digits for local calls.
