Calling 737 numbers legally

Texas is stricter than federal law. Texas allows solicitation calls only after 9 a.m. and before 9 p.m. on weekdays and Saturdays, and only between noon and 9 p.m. on Sundays. Because the window follows the called party's local time, a 737 number is governed by Texas 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.
