About American Samoa Calling Code

American Samoa's international dialing code is +1. This code is assigned by the International Telecommunication Union (ITU) and must be dialed before the local phone number when calling American Samoa from another country. American Samoa is located in Oceania.

ITU-T E.164 assigns American Samoa the calling code +1, in Polynesia. The code is not a domestic prefix: it exists purely to route traffic into American Samoa's network from abroad, and it is replaced by the national trunk prefix once the call is inside the country.

Where the +1 Calling Code Is Used

The country code +1 is assigned to American Samoa, located in Polynesia, with the capital Pago Pago. This code is part of the international telephony numbering plan and is used for all calls made to American Samoa from outside the country.

When you see a phone number written as +1 ..., the +1 prefix tells your telephone network to route the call to American Samoa's national telephone network. After the country code, you dial the local area code (dropping any leading 0) and the subscriber number. The same format applies whether you are calling a landline or a mobile phone.

Country codes are allocated by the International Telecommunication Union (ITU-T Recommendation E.164) and are grouped by geographic region. Calling codes starting with 1 are generally assigned to the region around American Samoa, in Polynesia. When a phone number is stored internationally, the leading zeros of the domestic area code are omitted after the country code — this is why you will often see numbers written as +1 followed directly by the area code and number.

The country code +1 is shared with United States, Canada, Anguilla, Antigua and Barbuda, Bahamas, Barbados, Bermuda, Cayman Islands, Dominica, Dominican Republic, Grenada, Guam, Jamaica, Montserrat, Northern Mariana Islands, Puerto Rico, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Sint Maarten, Trinidad and Tobago, Turks and Caicos Islands, US Virgin Islands, British Virgin Islands. After dialing +1, the following digits (area code + subscriber number) route the call to the correct country, so you must always include the full national number.

American Samoa Phone Number Formats

Phone numbers in American Samoa follow the ITU E.164 international format: country code + area code + subscriber number. Below is the general structure used for both landlines and mobile numbers.

If a American Samoa number starts with 0, do not dial that 0 from abroad — it tells the national network 'this call is local'. Your own exit code followed by +1 takes its place, and the remaining digits are unchanged. Numbers in American Samoa follows the published pattern +1-684-XXX-XXXX.

Time Zone in American Samoa

American Samoa is in the Pacific/Pago_Pago time zone, which is UTC-11:00 relative to Coordinated Universal Time (UTC). If you are calling from a different time zone, remember to account for the time difference when scheduling your international call.

When planning a call to American Samoa, the time difference matters: a good time to reach businesses in Pago Pago, the capital, during their working hours may be early morning or late evening in your own time zone. Many international callers use the UTC offset as a quick reference to avoid calling in the middle of the night.

Some countries observe daylight saving time (DST), which shifts the local clock by one hour during summer months. If American Samoa uses DST, the effective offset changes twice a year — check the current UTC offset before dialing if your call is time-sensitive. For most purposes, however, the standard offset shown above is sufficient.
