About Antigua and Barbuda Calling Code
Antigua and Barbuda'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 Antigua and Barbuda from another country. Antigua and Barbuda is located in North America.
Country calling codes (also known as ISD codes or dialing codes) are telephone numbering plan prefixes defined by ITU-T standards E.123 and E.164. Each country is assigned one or more unique prefixes to facilitate international direct dialing.
Where the +1 Calling Code Is Used
The country code +1 is assigned to Antigua and Barbuda, located in Caribbean, with the capital Saint John's. This code is part of the international telephony numbering plan and is used for all calls made to Antigua and Barbuda 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 Antigua and Barbuda'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 Antigua and Barbuda, in Caribbean. 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, American Samoa, Anguilla, 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.
Antigua and Barbuda Phone Number Formats
Phone numbers in Antigua and Barbuda 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.
📱 Number Structure
- International format: +1 [area code] [subscriber number]
- From abroad: exit code + +1 + local number (drop the trunk prefix 0)
- Within Antigua and Barbuda: dial the local number directly
Most countries use a closed or open telephone numbering plan. In an open plan, the length of local numbers varies and the trunk prefix (usually 0) is dropped when dialing internationally. In a closed plan, all national numbers have a fixed length regardless of area. When dialing Antigua and Barbuda from abroad, always replace the leading trunk zero with the country code +1.
Time Zone in Antigua and Barbuda
Antigua and Barbuda is in the America/Antigua time zone, which is UTC-04:00 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 Antigua and Barbuda, the time difference matters: a good time to reach businesses in Saint John's, 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 Antigua and Barbuda 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.
