Calling 820 numbers legally

California is stricter than federal law. California prohibits automated and solicitation calls before 9 a.m. or after 9 p.m. local time (Public Utilities Code § 2875): a 9 a.m. start, stricter than the federal 8 a.m. Because the window follows the called party's local time, a 820 number is governed by California 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.
