North American NumbersAmerican Samoa
Area code 684 is the sole area code for the U.S. territory of American Samoa, the only NANP area south of the equator. It reuses the territory's former ITU country code, adopted when American Samoa joined the NANP in the mid-2000s.
Status, dates and counts are read from NumberResearch (NANPA / CNAC / FCC records). Assignment records show initial assignees, not the carrier serving a number today.

How it relates to other codes
The codes 684 was split from, spawned, or shares its area with. A split divides the map and changes some numbers; an overlay shares the same ground and changes none — what's the difference?
