How to Stop Robocalls: Every Method That Actually Works (2026)
Robocalls hit Americans over 4 billion times a month. Here's the complete, current playbook: carrier tools, phone settings, the Do Not Call Registry, and what to do when nothing else works.

Start with your carrier's free tools
All three major US carriers now ship free network-level spam blocking, and they catch more than any app because they see the call before your phone rings. AT&T's ActiveArmor, Verizon's Call Filter and T-Mobile's Scam Shield all label or outright block calls their networks flag as likely scams. If you do nothing else, activate the one for your carrier — each takes under five minutes from the carrier's app.
The paid tiers of these services add caller ID for unknown numbers and personal block lists, but the free tier does the heavy lifting. Prepaid brands (Cricket, Metro, Visible) inherit the parent network's filtering.
Use your phone's built-in screening
iPhone: Settings → Phone → Silence Unknown Callers sends any number not in your contacts, recent outgoing calls or Siri suggestions straight to voicemail. It's blunt but devastatingly effective if most legitimate calls in your life come from saved contacts.
Android: Google's Call Screen (Pixel and many others) answers unknown calls with an assistant, transcribes what the caller says in real time, and lets you decide. Robocall systems typically hang up the moment they hit screening.
Register on the Do Not Call Registry — and know its limits
Register free at donotcall.gov. Legitimate telemarketers must stop calling within 31 days, and registration never expires. But scammers ignore the registry by definition — so treat it as a filter that removes the legal calls, making everything that remains automatically suspect.
After registering, any sales call you still get is either a scammer or a company breaking the law. Both are worth reporting.
Report the calls — it matters more than you think
Report unwanted calls to the FCC (consumercomplaints.fcc.gov) and the FTC (reportfraud.ftc.gov). These complaints become public data — WhoCalledLookup and other services surface them so the next person who searches the number sees the warning. Enforcement actions against robocall operations are built on exactly this complaint data.
Also report the specific number on its WhoCalledLookup page: community reports describing what the call actually said are the single most useful signal for other recipients.
Got a call from an unknown number?
Look it up free — carrier, location, FCC complaints and first-hand reports.
FAQs
Why do robocalls come from numbers that look like mine?
That's 'neighbor spoofing' — the caller fakes a number sharing your area code and prefix so the call looks local and familiar. The displayed number often belongs to an innocent person. Never trust caller ID alone; look the number up first.
Does answering a robocall make it worse?
Yes. Answering — and especially pressing a digit to 'opt out' — confirms your number is live and answered by a human, which raises its value on calling lists. Let unknown calls go to voicemail.
Are robocall-blocking apps worth paying for?
Try the free carrier tools and built-in phone screening first — for most people they're enough. Paid apps add convenience (reverse lookup, personal block lists) but work from the same underlying signals.
