How do I dial mobiles vs landlines in the Northern Mariana Islands
The Northern Mariana Islands (CNMI) is part of the North American Numbering Plan (NANP), so it uses country code +1 and area code 670. That means a CNMI number looks like a US-style number: +1 670 XXX XXXX. If you’re calling from the US or Canada, you typically dial 1 670 XXX XXXX; from most other countries, dial your international exit code (or +) then 1 670 XXX XXXX. 
In CNMI, mobiles and landlines follow the same NANP format (there isn’t a special “mobile area code”). The practical difference is mostly which local 670-XXX exchange the number is in and which provider issued it. To avoid failed calls—especially from mobile phones, PBXs, or when you’re roaming—use 10-digit dialing (include 670) for local calls, and save contacts as +1 670 … in your phone. Some carriers explicitly advise dialing 670 + the 7-digit number for calls from mobile lines in CNMI.
