Calling 667 numbers legally

Maryland is stricter than federal law. Maryland's 2023 Stop the Spam Calls Act bars solicitations before 8 a.m. or after 8 p.m.: an 8 p.m. cap. Because the window follows the called party's local time, a 667 number is governed by Maryland rules no matter where you are dialing 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.
