The area code 684 is located in Pago Pago, American Samoa.
Area code 684 serves all of American Samoa, centered on the harbor town of Pago Pago in the South Pacific. As part of the North American Numbering Plan (NANP) under country code +1, this area code connects the territory to U.S. phone networks. It covers the main island of Tutuila (home to Pago Pago), nearby Aunu’u, the Manu’a Islands (Ta’u, Ofu, and Olosega), and remote Swains Island. Sitting just east of the International Date Line in Samoa Standard Time (UTC−11), American Samoa is one of the last places to welcome each day.
Area code 684 was established in 2004, when American Samoa joined the NANP; before that, callers used the separate international country code +684. Today, American Samoa phone numbers use the familiar format 1-684-xxx-xxxx, making calls to and from the U.S. straightforward. There are no overlays—684 is the only area code for the territory. That makes it easy to spot a Pago Pago area code on caller ID.
This area code spans key communities and landmarks, from the deep, natural Pago Pago Harbor to the National Park of American Samoa across Tutuila and the Manu’a Islands. Tafuna hosts the main gateway, Pago Pago International Airport, while villages like Leone, Fagatogo, and Nu’uuli anchor daily life and commerce. The 684 area code links government offices, schools, small businesses, and tourism across volcanic peaks and coral-fringed coasts. It keeps residents connected across the Pacific and to the mainland United States.
