How to stop robocalls legally (And sue for violations)

Robocalls are often illegal, not just annoying. The Telephone Consumer Protection Act (TCPA) lets you sue on your own and collect $500 to $1,500 in statutory damages per illegal call. That turns a nuisance into a real claim.

1. Register on the National Do Not Call list

Add your number at donotcall.gov. After 31 days, most legitimate telemarketers must stop calling. Scammers ignore the list, but registering creates a paper trail that supports a TCPA claim.

2. Know what the TCPA bans

Under 47 USC 227, autodialed or pre-recorded calls to your cell phone, and unsolicited robocalls to landlines, require your prior express consent. No consent means $500 per call, tripled to $1,500 if the caller acted willfully.

3. Log every illegal call

Record the date, time, number, and what the call said. Save voicemails. If a live person picks up, ask for the company name and address. This log is your evidence in a TCPA case.

4. Turn on call-blocking tools

Major carriers offer free spam blocking: T-Mobile Scam Shield, AT&T Active Armor, Verizon Call Filter. Apps like Robokiller, Hiya, and Truecaller add a layer. iPhone and Android can also silence unknown callers in settings.

5. Sue or join a class action

TCPA cases often settle for thousands of dollars per consumer, and many TCPA lawyers take cases on contingency. Class actions against major spam callers recover seven and eight figures, with individual payouts in the hundreds.
