American Samoa Country Code +1 684
American Samoa is an unincorporated territory of the United States in the South Pacific and uses the North American Numbering Plan (NANP) country code +1 684. You will see +1 684 on calls and messages related to Pago Pago’s harbour and government offices, telecom and satellite facilities around Tafuna, small businesses across Tutuila and the outer islands, and families in close contact with relatives in Hawaii and mainland USA.
Phone numbers are typically written internationally as +1 684 633 1234. Locally, people often use the 7-digit part (633-1234) in everyday speech. Because American Samoa is part of the NANP, numbers follow the familiar 1 + NPA + NXX-XXXX pattern used in the United States and Canada, but with 684 acting as the geographic code for the entire territory.
This page explains how +1 684 numbers are structured, how to dial American Samoa from inside the US/Canada and from overseas, how the Pacific/Pago_Pago (UTC-11) time zone fits into international schedules, and practical tips for working with shipping lines, call centres, remote workers and island businesses.
Don’t confuse: +1 684 (American Samoa) with the independent state of Samoa, which uses country code +685 and sits a full day ahead in the time-zone sense.
Example fixed / business line
+1 684 633 1234
Representative 7-digit local number in NANP format. The 684 block covers the territory instead of multiple city area codes.
Example mobile line
+1 684 733 4567
Mobile and landline numbers share the same 7-digit format; the first digits of the local part show which block/operator they belong to.
Time & region
Pacific/Pago_Pago (UTC-11)
One of the last time zones on earth to reach each date; useful for end-of-day support windows for the Americas and Asia-Pacific.
Overview – what +1 684 tells you about the caller or customer
The prefix +1 684 identifies American Samoa inside the broader +1 North American Numbering Plan. A +1 684 number usually belongs to:
- • A local resident or family household on Tutuila or the outer islands.
- • Shipping, fishing and logistics companies using Pago Pago harbour as a hub.
- • Government, health or education services serving the territory.
- • Satellite, telecom or data facilities bridged into Pacific networks.
- • Tourism operators working with visitors from the US, New Zealand, Australia or Asia.
For many systems, American Samoa appears in the same “+1 world” as US states, Canada and other Caribbean territories, but with an extreme-west time zone (UTC-11). This combination makes +1 684 useful for end-of-day coverage and for supporting Pacific routes that still need NANP interoperability.
Typical +1 684 scenarios for telecom & SaaS
- Account security – SMS OTP and voice verification for users registering from American Samoa.
- Customer support routing – directing calls from +1 684 numbers to a Pacific-focused support queue.
- Logistics updates – delivery notifications and port status messages to phones in and around Pago Pago.
For these use cases, treat +1684 as a normal NANP country/area code, and normalise all local numbers to +1684XXXXXXX to avoid failed calls when the same user travels to the mainland or abroad.
American Samoa phone number formats (+1 684)
Pattern: +1 684 XXX XXXX (NANP, 7-digit local)As part of the North American Numbering Plan, American Samoa uses the common +1 NPA NXX-XXXX structure. Here:
- • +1 is the shared NANP country code.
- • 684 acts as the territory-wide “area code” for American Samoa.
- • NXX-XXXX is the 7-digit local number.
There is no separate trunk prefix 0. Inside the territory you usually dial the 7-digit local number directly. From other NANP countries (US, Canada, etc.) you dial 1-684-XXX-XXXX, and from the rest of the world you dial your international prefix (often 00) followed by 1-684-XXX-XXXX.
For E.164-compliant storage, strip punctuation and save numbers as +1684 followed by
the 7-digit local part (for example +16846331234). Any input such as
6846331234 or 1-684-633-1234 can be parsed to the same canonical representation.

How to dial American Samoa (+1 684)
1. From the USA or Canada (NANP)
From the mainland US, Canada and other NANP locations, American Samoa is dialled like a long-distance call:
- Dial 1 – NANP long-distance prefix.
- Dial 684 – American Samoa code.
- Dial the 7-digit local number.
Example (California → Pago Pago line 633-1234): 1 684 633 1234.
2. From Europe or outside NANP
From most other countries, American Samoa is dialled like any +1 destination:
- Dial your international access code (often 00 or +).
- Dial 1 – NANP country code.
- Dial 684 – American Samoa code.
- Dial the 7-digit local number.
Example (UK → mobile 733-4567): 00 1 684 733 4567.
3. Within American Samoa & calling abroad
- Inside American Samoa: dial the 7-digit local number directly (for example 633-1234 or 733-4567).
- To US states / Canada: dial 1 + area code + 7-digit number (for example 1-808-555-1234 to call Hawaii).
- To non-NANP countries: dial 011 + country code + national number.
For software systems, the safe approach is to always store American Samoa numbers as +1684XXXXXXX and let diallers / devices handle whether a leading 1 or international access code is needed.
Normalisation tip: if a user enters 6846331234, 1-684-633-1234 or
+1 684 633 1234, strip all non-digits, remove any leading 1 if
followed by 684…, verify that you end with 684 plus 7 digits,
then store it as +1684 and the 7-digit local number.
Time in American Samoa – Pacific/Pago_Pago (UTC-11, no DST)
American Samoa uses the IANA time zone Pacific/Pago_Pago, with a fixed offset of UTC-11. The territory does not observe daylight saving time, making it one of the last places on earth to reach any given calendar date.
For scheduling:
- • American Samoa is typically one hour behind Hawaii (UTC-10).
- • It can be 21–23 hours behind many Asian cities, depending on their DST rules.
- • It aligns well with late-night support coverage for US West Coast and Hawaii.
In time-zone aware applications, always store times with the correct zone Pacific/Pago_Pago. This allows you to present local time correctly while still converting to UTC and to other cities such as Los Angeles, Honolulu, Auckland or Sydney.
Pacific/Pago_Pago compared with other hubs (typical)
| City / region | Time zone | Relation to Pago Pago |
|---|---|---|
| Pago Pago | Pacific/Pago_Pago (UTC-11) | Reference |
| Honolulu | Pacific/Honolulu (UTC-10) | Usually 1 hour ahead of American Samoa |
| Los Angeles | America/Los_Angeles | ≈ 2–3 hours ahead (depending on US DST) |
| New York | America/New_York | ≈ 5–6 hours ahead (depending on US DST) |
| Auckland | Pacific/Auckland | ≈ 23–24 hours ahead (close to a full day difference) |
| Samoa (Apia) | Pacific/Apia | Typically on the opposite side of the date line compared with Pago Pago |
Because American Samoa is so close to the International Date Line, always show both the local date and time when scheduling calls with contacts there.
Safety & emergency calls in American Samoa
As a U.S. territory, American Samoa generally uses short emergency numbers similar to those used in the mainland, most notably 911 for combined emergency response. Additional territory-specific numbers or hotlines may be available for non-urgent situations.
