Overview of American Samoa Area Code 684
Area code 684 is the sole area code serving American Samoa, an unincorporated U.S. territory in the South Pacific. Geographically, it covers the entire territory, including the main island of Tutuila, where the capital Pago Pago is located, as well as the Manu'a Islands (Ofu, Olosega, and Ta'u) and the remote atolls of Rose and Swains. Because the territory is small, 684 is a single-rate center, meaning there are no additional local area codes or overlay codes. The numbering plan area (NPA) 684 is administered under the North American Numbering Plan (NANP), despite the territory's Pacific location.
Dialing Formats and Call Routing
For local calls within American Samoa, callers must dial the 10-digit number in the format 684-XXX-XXXX. The seven-digit local number is not valid for local calls; the area code is an integral part of the dialing procedure. For calls originating from the U.S. mainland or other NANP countries, the international format is +1 684 XXX XXXX. When dialing from outside the NANP, replace the plus sign with the international access code (e.g., 011 from the U.S., 00 from most other countries).
Example: To call a business in Pago Pago from abroad, dial +1 684 555 0123. From a U.S. landline or mobile, dial 1 684 555 0123.
Telecom Infrastructure and Numbering
American Samoa's telecom infrastructure is served by a mix of fixed-line, mobile, and VoIP providers. The area code 684 is classified as a geographic code, but due to the territory's small population (about 55,000), it also serves mobile numbers. Mobile numbers in American Samoa are not distinguished by a separate prefix; they share the same 10-digit format. The numbering plan is managed by the U.S. Federal Communications Commission (FCC) and the North American Numbering Plan Administration (NANPA).
Callers should note that American Samoa is on the other side of the International Date Line from the U.S. mainland, so time zone differences (UTC-11) may affect business hours. For international callers, it is essential to use the correct country code (+1) and area code (684) to avoid misrouting to other NANP locations.
Regulatory and Porting Considerations
Number portability is available in American Samoa, allowing users to retain their numbers when switching providers. However, because the territory is remote, some advanced services like 911 emergency calling may have limitations compared to the mainland. For VoIP users, it is crucial to provide accurate location information for emergency services. Overall, area code 684 is a straightforward geographic code with no overlays, making dialing predictable for both local and international callers.
