The 684 area code serves American Samoa, an unincorporated United States territory in the South Pacific roughly 2,600 miles southwest of Hawaii. Pago Pago, the territorial capital and largest settlement, anchors the directory's records for this code. The territory consists of a string of volcanic islands and one coral atoll; Tutuila, the largest island, holds Pago Pago Harbor, which is among the deepest natural harbors in the South Pacific and a center for tuna canning and inter-island shipping. The 684 code is a relatively recent addition to the North American Numbering Plan, joining American Samoa to the same dialing framework used across the United States and several other Pacific and Caribbean territories.
For records associated with 684 numbers, the directory does not currently surface a working list of secondary cities, in part because the population is concentrated and the territory's place names are not a frequent target of cross-jurisdictional linkage in the public-record sources we draw on. Our prefix-record holdings for 684 are similarly limited at present, and what we do track should be read as a working subset rather than a definitive count — actual prefixes in service are not fully represented here.
Demographic figures we use to compare cities to US medians are not available for American Samoa in the same form as for the fifty states, and the standard four-metric profile is not represented in our data for Pago Pago. The territory's population has historically counted in the tens of thousands and is highly concentrated on Tutuila.
