Calling 670 numbers legally

Northern Mariana Islands has no calling-hour statute stricter than federal law, so the TCPA and the FTC's Telemarketing Sales Rule set the window: solicitation calls only between 8 a.m. and 9 p.m. in the called party's local time. Because the rule follows the called party, a 670 number is on Chamorro Time regardless of where you dial from.

Ringless voicemail sits under the same rules as a live call, which is why TCPA compliance matters before you drop to a list. To check a whole list rather than one code, the phone number formatter tags every number with its state so you can segment sends by time zone.
