Identify the caller first04 / The Defensive Toolbox
Seven ways to stop them — free, legal, effective.
Layer these in order. The registry cuts legitimate telemarketers; carrier + device filters silence the rest; reporting forces enforcement. None costs you a cent.
National Do Not Call Registry
Register your number with the FTC. Legitimate telemarketers (not political, charity, debt, or scam callers) must stop within 31 days.
- ·Go to donotcall.gov and add your number(s).
- ·Confirm via the verification email for each number.
- ·Report any sales call received after the 31-day window.
Report to the FTC
File a consumer fraud report for scam calls, deceptive sales, and unwanted robocalls. Reports feed federal enforcement.
- ·Visit reportfraud.ftc.gov and choose 'Phone, internet, TV'.
- ·Provide the caller's number and what was said.
- ·Submit — your report joins the FTC's scam database.
File an FCC Complaint
Formal telecom complaint. Most effective for spoofed Caller ID, DNC violations, and texts without consent. Carriers must respond.
- ·Open consumercomplaints.fcc.gov.
- ·Choose 'Unwanted calls' or 'Spoofing/Caller ID'.
- ·Include the number, date, and whether you consented.
Forward spam texts to 7726
Forward any spam text to SPAM (7726) — free on all major US carriers. Carriers use these to block the sender network-wide.
- ·Press and hold the spam message, tap Forward.
- ·Send it to 7726.
- ·Follow your carrier's reply prompts (usually free).
Activate carrier call-blocking
Every major US carrier offers free scam-blocking. Turn it on — it flags likely-robocall numbers before your phone rings.
- ·Install your carrier's protection app (free).
- ·Enable 'Scam Block' / 'Filter suspected spam'.
- ·Optionally block all unknown numbers.
Silence unknown callers
Built into iOS and Android. Calls from numbers not in your contacts go straight to voicemail — scammers rarely leave one.
- ·iPhone: Settings ▸ Phone ▸ Silence Unknown Callers ▸ On.
- ·Android: Phone app ▸ ⋮ ▸ Settings ▸ Caller ID & spam ▸ Filter spam calls.
- ·Real callers can still leave a voicemail.
Block the number directly
The fastest fix for a repeat offender. Blocked numbers can't reach you, but may simply spoof a new number — combine with the tools above.
- ·iPhone: Recents ▸ � ⓘ next to the number ▸ Block this Caller.
- ·Android: Recents ▸ long-press the number ▸ Block/report spam.
- ·Blocked calls still hit voicemail.
Send a legal revocation letter.
The TCPA lets you revoke consent to automated calls and texts in writing. Fill in the caller's details and generate a formal cease-and-desist letter — copy it, or download as a PDF to send by certified mail.
Enter a caller/company name to enable.
This generator produces a consumer self-help revocation/cease letter, not legal advice. The TCPA authorizes statutory damages for violations; consult an attorney before filing suit.
