## History of area code 684

American Samoa was the last US territory to join the North American Numbering Plan, on October 2, 2004, taking area code 684 — the same digits as its previous ITU country code, +684. Before the change, a call from the US mainland was dialed as an international call (011 684); joining the plan made it a domestic +1 call.

## How to dial a 684 number

- From the mainland US or Canada: 1 + 684 + 7-digit local number. The call is domestic — no international prefix and no international rates; normal long-distance or mobile charges apply.
- From outside the NANP: your country's exit code, then 1 684 and the local number, or +1 684 from a mobile.
- Inside American Samoa: the local number, per the local dialing plan.
- 684 is a US area code, but caller ID is trivially spoofed — the code alone still does not verify who is calling.

## Frequently asked questions about area code 684

### Where is area code 684?

684 is the area code for American Samoa, a US territory. It is part of the North American Numbering Plan (NANP), sharing the +1 prefix with the rest of the US and Canada — and unlike the Caribbean nations in the plan, it is US soil, so calls to and from the mainland are domestic.

### How do I call American Samoa from the US or Canada?

Dial 1 + 684 + 7-digit local number. The call is domestic — no international prefix and no international rates — though some mobile plans price the island territories separately, so check yours before a long call.

### Is area code 684 a scam?

Not by itself. 684 is a legitimate US area code serving American Samoa. Caller ID is trivially spoofed, though, so an unexpected call from 684 deserves the same caution as any unknown number — verify the caller before returning the call.

### Does 684 have an overlay?

No. 684 is currently the only area code in service for American Samoa.

### What is the timezone of area code 684?

American Samoa observes Pacific/Pago_Pago (UTC−11, no DST) and does not change clocks for daylight saving time, so the offset from the mainland shifts by an hour when the mainland does.

Area code 684 went into service on October 2, 2004.

### What is the population of American Samoa?

American Samoa has a population of approximately 49,710 (2020). The capital is Pago Pago, and the territory covers 199 km².
