About Dominica Calling Code
To reach Dominica from another country, first dial the international calling code +1 — assigned by the ITU — followed by the local number. Dominica is located in North America, in Caribbean.
Dominica is known locally as Commonwealth of Dominica — Roseau is the capital. When saving an international contact, write the number in full international format with +1 so it works from any country.
International calling codes follow the ITU-T standards E.123 and E.164, which define how phone numbers are written and dialed across borders. The prefix you dial after the exit code tells the global telephone network which national network to route the call to.
Where the +1 Calling Code Is Used
The country code +1 is assigned to Dominica, located in Caribbean, with the capital Roseau. This code is part of the international telephony numbering plan and is used for all calls made to Dominica from outside the country.
When a number is written as +1 …, the +1 prefix directs your call to the Dominica national network. After the prefix, dial the area code without its leading zero, then the subscriber number — the same pattern for landlines and mobiles.
ITU-T E.164 groups calling codes by world region; codes beginning with 1 cover the part of the world that includes Dominica, in Caribbean. Storing numbers with +1 and omitting the domestic leading zero keeps contacts dialable from anywhere.
The country code +1 is shared with United States, Canada, American Samoa, Anguilla, Antigua and Barbuda, Bahamas, Barbados, Bermuda, Cayman Islands, 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.
Dominica Phone Number Formats
The ITU E.164 format for Dominica numbers is +1 + area code + subscriber number, used for landlines and mobiles alike. Here is the general structure:
📱 Number Structure

Time Zone in Dominica
The local time in Dominica follows the America/Dominica time zone (UTC-04:00 UTC). Check the time difference before you dial so your call arrives during waking hours.

If Dominica observes daylight saving time, its UTC offset shifts by an hour twice a year. Double-check the current offset before time-sensitive calls, especially in spring and autumn.

🌍 From the United States or Canada
- Dial the US/Canada exit code 011

Example: 011 +1 [area code] [number]
