American Samoa at a glance
The numbers and facts you need before you dial.
What is the country code for American Samoa?
American Samoa is one of the more counterintuitive entries in any country-code reference, because on paper it barely qualifies as "international" at all.
As a US territory, American Samoa is folded into the North American Numbering Plan (NANP) under area code 684 — the same numbering system used by the United States, Canada, and a cluster of Caribbean nations.
A call from New York or Los Angeles to Pago Pago is dialed exactly like a domestic long-distance call: no country code override, no exit-code gymnastics, just 1 + 684 + the seven-digit local number.
That single fact sets up the most important distinction on this page. Sixty-some miles away sits independent Samoa, a fully sovereign nation with its own country code, +685. Two territories, similar names, similar culture and language, completely separate telecom identities.
Confusing +1 684 (American Samoa) with +685 (independent Samoa) is one of the most common numbering errors in the Pacific region — and the two also sit on opposite sides of the International Date Line, adding a second layer of confusion for anyone coordinating business across both.
Code +1 684 was assigned to American Samoa by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to American Samoa.
How to call American Samoa from anywhere
To a US or Canadian phone, 684 behaves like any home-grown area code — dial 1 + 684 + the seven-digit number.
The distinction only appears once you leave the NANP: from the UK, Europe or anywhere else, you're back to your normal exit code before the +1. From the UK, that's 00 1 684 XXX XXXX; from Australia, 0011 1 684 XXX XXXX. Out of American Samoa to a non-NANP destination, use 011 as the exit code.
Full example: +1 684 684 XXX XXXX — drop the local leading 0 when calling from abroad.
American Samoa phone number format explained
An American Samoa number is always 10 digits in NANP shape: the 684 area code plus a 7-digit subscriber number (three-digit exchange + four-digit line number). There's no domestic trunk prefix to puzzle over — no stray 0 to add or strip — so within the NANP you simply dial 1-684-XXX-XXXX every time.
Local dialing within the territory typically only requires the seven-digit number, though including 684 is always safe and increasingly standard as mobile use grows.

American Samoa mobile network prefixes
The prefix after +1 684 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.

American Samoa time zone
American Samoa operates on Samoa Time Zone (SST), UTC-11, and does not observe daylight saving time. This places it among the furthest-behind time zones in the world — one of the last places on Earth to greet the new day, in stark contrast to independent Samoa and Tonga, which are among the first.
Practical reference points: American Samoa is roughly 3 hours behind US Pacific Time and 6 hours behind US Eastern Time, roughly 21–22 hours behind Sydney, and a full 24 hours behind independent Samoa.
Any business coordinating calls, deliveries or support SLAs with American Samoa should build scheduling around US mainland business hours logic, not Pacific/Australia-adjacent logic — despite the geography suggesting otherwise.

Common mistakes when calling American Samoa
Almost every failed international call is a formatting issue, not a network issue.
Confusing American Samoa (+1 684) with independent Samoa (+685)
By far the most frequent error. Two different countries, two country codes, two currencies (USD vs. Samoan Tālā), and — critically — two different sides of the International Date Line. Double-check which "Samoa" a contact, customer or shipment actually refers to before dialing or scheduling anything.
Adding an international exit code when calling from the US or Canada
Because American Samoa is part of the NANP, US and Canadian callers should dial it like a domestic long-distance number (1 + 684 + number), not with an international prefix like 011.
Assuming American Samoa shares a time zone with nearby Pacific nations
Its UTC-11 offset is not shared with Fiji, Tonga or independent Samoa — all of which sit on the other side of the date line. Scheduling "Pacific region" calls as if they're all in sync will cause missed meetings.
Treating the numbering format as unfamiliar or requiring special international dialing knowledge
It follows the exact NANP structure used across the US and Canada — no unusual formatting to learn. The mistake here is usually overcomplicating something that is actually simple.
Tips to reduce the cost of calling American Samoa
Route calls through VoIP, apps or an MCM virtual number rather than paying carrier international rates into 684.
Read the fine print on your plan
many "unlimited US/Canada" bundles quietly treat 684 (and other Pacific NANP territories) as separate international destinations.
Pick up an American Samoa virtual DID so islanders reach you at a local rate instead of an overseas one.
Always label the Samoa you mean
in customer-facing scheduling and shipping, spell out "American Samoa" or "independent Samoa" — never just "Samoa" — to prevent the 24-hour date-line mix-up.
Why businesses get a American Samoa virtual number
On a small territory where everyone recognizes a 684 number, that area code is what tells customers you're genuinely here — and it shows up in pick-up rates.
Because American Samoa numbers behave exactly like domestic US numbers for dialing purposes, US-based sales, support or operations teams face no additional dialing friction when reaching customers or partners there.
Presence without physical infrastructure
a local +1 684 virtual number lets a business establish a recognizable American Samoa presence — useful for logistics, tourism, government-adjacent services, or diaspora-facing companies — without opening a physical office in the territory.
NANP simplicity for US-based teams
American Samoa numbers behave exactly like domestic US numbers for dialing purposes, so US-based sales, support or operations teams face no additional dialing friction.
Serving a small but distinct market correctly
with a modest population and a close-knit community, getting local dialing conventions and time zone alignment right builds trust quickly — and getting them wrong is noticed just as quickly.
Coordinating across two Samoas without confusion
companies with any footprint spanning both American Samoa and independent Samoa benefit from clearly separated number ranges (+1 684 vs. +685) and explicit time zone labeling in every customer-facing communication.
Resilient connectivity for a geographically isolated market
cloud-based virtual numbers route calls over infrastructure that doesn't depend on any single local carrier or submarine cable link, which matters in a territory where local network capacity is limited relative to mainland markets.
Real PSTN presence
a true 684 number on the network, not a forwarding workaround.
