How to Call North Marianas Islands from the U.S.

It’s easy to call the Commonwealth of the Northern Marianas Islands from the United States.

Because the Northern Marianas Islands is part of the North American Numbering Plan, the process is the same as making a call within the United States:

  • First dial 1, the country code for the Northern Marianas Islands.
  • Next dial 670, which is the area code.
  • Then dial the seven-digit local phone number.

Calls made through the Ooma Mobile app do not use any cellular minutes or incur international charges on your wireless bill. Instead, these calls are routed over your data connection and may count against the data allotment with your cellular phone provider if you are not connected to Wi-Fi.
