Is area code 670 a scam?

No, 670 is a legitimate area code for the Commonwealth of the Northern Mariana Islands, a U.S. territory in the Pacific. While it is part of the North American dialing plan, calls to this region are technically long-distance and may incur higher rates depending on your phone service provider. Fraudsters spoof this code because its U.S. association makes it look safe, even though the call may be coming from halfway around the world.

Because the 670 code is obscure to most mainland Americans, it is an effective tool for masking the origin of these deceptive telemarketing campaigns.
