Calling 618 numbers legally

Illinois is stricter than federal law. Illinois's Automatic Telephone Dialers Act bars autodialer calls between 9 p.m. and 9 a.m.: a 9 a.m. start, stricter than the federal 8 a.m. Because the window follows the called party's local time, a 618 number is governed by Illinois 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.
