Every American Samoa code keeps Samoa time.
American Samoa dials like any US state: it joined the North American Numbering Plan when 684 entered service in 2004, replacing the old international dialing route. Calls between the mainland and American Samoa are domestic long-distance, not international.
684 has served Am Samoa since 2004, carries 21 active prefixes across 1 rate centers, split among 2 carriers. It is the only area code serving American Samoa. Local calls can still be dialed with seven digits — increasingly rare in the NANP.
Numbers in the toll-free 8YY family are absent here by design: they carry no state assignment and answer anywhere in the US, Canada and the Caribbean.
