Understanding Spam Calls: Types, Laws, and Your Rights (TCPA Explained)

Spam calls include robocalls (pre-recorded messages), autodialed calls (using automatic dialing systems), and telemarketing pitches. Illegal if unsolicited, especially to numbers on the National Do Not Call Registry (donotcall.gov).

TCPA (Telephone Consumer Protection Act): Bans autodialed/prerecorded calls to cells without consent. Fines: $500–$1,500 per call. State laws (e.g., Florida's mini-TCPA) add enforcement via Attorneys General.

Your Rights:

• Block and report.
• Sue in small claims or join class actions (average win: $500–$10K).
• Demand carrier action under STIR/SHAKEN rules (2021 mandate).

Federal TCPA preempts some state laws, but AGs handle local telemarketing scams.
