How do you dial a 679 number?
Use the North American country calling code +1 followed by the three-digit area code and seven-digit local number. For example, write the pattern as +1 679 XXX XXXX. Local dialing rules and charges depend on your location and provider. Check a supported dialing format or check NANPA’s 10-digit dialing list.

The displayed number may be spoofed. Do not rely on an area code as proof of caller identity. If the caller claims to represent a business, end the call and contact that business using a number you found independently.
Common questions about 679
What time zone is area code 679 in?
679 is assigned to Michigan, and the NANPA record associates it with Eastern time. A phone number does not reveal its owner’s current time zone. The clock above uses a representative time zone for the numbering area.
Does 679 mean the caller is in Michigan?
No. An area code is an assignment, and a person can travel, move, use internet calling, or display a spoofed number.
Can this page identify who called?
No. OfficialAreaCode has no live subscriber directory or spam-report database.
