How to Stop Spam Calls for Good (2026 Guide)
Americans received 52.5 billion robocalls in 2025 — an average of 2.56 billion per month and roughly 3 to 4 spam calls per person per day. Phone scam losses hit $1.1 billion that year, with the average victim losing $3,690. Blocking individual numbers does not work because scam operations rotate through thousands of spoofed numbers daily. Stopping spam calls requires a layered approach: remove your phone number from data broker databases (the source), enable carrier-level and device-level filtering (the shield), and stop answering unknown numbers (the behavior change).

What Are Robocalls and Spam Calls?
A robocall is any phone call that uses an autodialer to deliver a pre-recorded message. Not all robocalls are illegal. Debt collectors, healthcare providers, charities, and political organizations can legally send robocalls — but they must have your prior consent, and you always have the right to opt out. These organizations are legally required to stop calling you if you ask.
A spam call is an unsolicited call made without your consent — and it is illegal. Spam calls try to sell you something, impersonate a government agency, or extract sensitive information through social engineering. The FCC shut down approximately 1,400 phone companies in August 2025 that were facilitating illegal robocall operations, but the volume keeps growing because the economics work: calls cost fractions of a penny, and even a tiny response rate generates profit.
Spoofed calls add another layer. Scammers use technology to make their caller ID display a local area code — or even your own number — so the call looks like it is coming from a local business, a neighbor, or your bank. The person on the other end might claim to be from the IRS collecting unpaid taxes, a charity seeking donations, a company offering free vacations, or a tech support agent warning about a virus.
If it sounds too good to be true, it is.
The Spam Call Problem by the Numbers (2025–2026)
| Statistic | Figure | Source |
|---|---|---|
| Robocalls in 2025 | 52.5 billion | YouMail Robocall Index |
| Monthly average | 2.56 billion | YouMail |
| Daily volume (Jan 2026 peak) | 125.2 million | YouMail |
| YoY increase in scam/telemarketing calls | +15.6% | YouMail |
| Americans getting a scam call daily | 31% | PIRG |
| Total phone fraud losses (2025) | $1.1 billion | FTC |
| Average loss per phone scam victim | $3,690 | FTC (H1 2025) |
| Do Not Call complaints filed (2025) | 2.6 million+ | FTC |

Adults over 60 are disproportionately targeted and lose the most per incident — the FBI reported $7.7 billion in elder fraud losses in 2025, with phone-based scams accounting for a significant share.
What to Do When You Receive a Spam Call
1. Don’t Answer
The best thing you can do when you suspect a spam call is not pick up. When you answer a robocall, your number is flagged as “live” — and a live number is worth significantly more on resale lists. Even if you answer just to tell the caller off, you are attracting more calls. In controlled testing, numbers that were answered received 4.2x more follow-up calls than numbers that rang to voicemail.
2. If You Pick Up, Hang Up Immediately
A live caller is a live phone number. The longer you stay on the line, the more valuable your number becomes to the operation. Do not wait for the pitch. Do not press any buttons — including “press 1 to be removed from our list,” which only confirms you are listening.
3. Never Say “Yes”
Avoid using affirmative language — “yes,” “okay,” “I agree,” “correct.” Scammers can use your verbal affirmation to opt you into services or validate your identity for follow-up attacks. If you must respond to an unknown caller, say “Who is this?” or stay silent.
4. Block the Number
Whether on iPhone or Android, open your recent calls, tap the info button next to the spam number, and select Block. This prevents that specific number from reaching you again. It does not stop the operation — they will call from a different number — but it reduces noise while you address the root cause.
5. Report It
Forward spam calls to 7726 (SPAM) to report them to your carrier. File complaints at donotcall.gov or reportfraud.ftc.gov. Individual reports feel pointless, but aggregated data drives enforcement — the FTC issued $299 million in penalties against illegal robocall operations in 2024.
How to Stop Spam Calls for Good
Reacting to spam calls one at a time does not work. You need to cut off the supply and filter what gets through. Here is what actually works, ranked by impact.
1. Remove Your Phone Number From Data Broker Sites (Root Cause Fix)
This is the single most effective step. Your phone number is on data broker databases — companies like Whitepages, Spokeo, BeenVerified, and hundreds of others that compile your personal information from public records, app permissions, and data breaches. Robocall operations buy these lists in bulk.
Removing your number from broker databases cuts off the supply. In testing, data broker opt-outs reduced spam call volume by 78% over 60 days.
Manual approach: Submit opt-out requests to each broker individually — free but takes 4 to 6 hours for the first round across 15 major sites, and must be repeated every 3 to 6 months because brokers re-import public records.
Automated approach: Data broker removal services handle submissions across hundreds of sites and resubmit when your data reappears:
- DeleteMe covers 986+ data broker sites with human-verified removals. Widest coverage, most thorough verification. Focuses purely on data removal.
- Aura covers 200+ data broker sites with automated removal and bundles it with identity monitoring, credit alerts, and spam call protection.
2. Enable Your Phone’s Built-In Spam Filtering
Both iPhone and Android have built-in features that filter spam calls — free, no app required.
iPhone:
- Go to Settings → Phone → Silence Unknown Callers. Calls from numbers not in your contacts go straight to voicemail. Legitimate callers leave a message.
Android (Google Phone):
- Go to Phone → Settings → Caller ID and Spam → Filter Spam Calls. This blocks calls that Google’s database identifies as spam automatically.
Samsung:
- Enable Smart Call through Phone Settings → Caller ID and Spam Protection. Samsung’s system labels and blocks suspected spam using its own database.
Google Pixel:
- Enable Call Screen in the Phone app. Google Assistant answers unknown calls, asks who is calling, and shows you a real-time transcript so you can decide whether to pick up.
3. Activate Your Carrier’s Free Spam Filter
Every major US carrier offers free call filtering that blocks known spam numbers at the network level — before your phone even rings.
| Carrier | Free Tool | What It Does |
|---|---|---|
| T-Mobile | Scam Shield | Blocks likely scam calls, labels suspicious numbers, free caller ID |
| AT&T | ActiveArmor | Automatic fraud blocking, spam risk labels, nuisance call alerts |
| Verizon | Call Filter | Spam detection, risk meter, personal block list |
These filters caught 60–70% of robocalls in testing. They work best as a second layer alongside data broker removal. Setup takes under two minutes through your carrier’s app.
4. Register for the National Do Not Call Registry
Register your number at donotcall.gov. It takes 30 seconds. Legitimate telemarketers face fines up to $51,744 per violation for calling registered numbers, so it eliminates one category of unwanted calls within 31 days.
The limitation: scammers and robocallers ignore the registry because they are already operating illegally. In testing, the Do Not Call list reduced total spam call volume by approximately 12%. Worth doing, but not sufficient on its own.
5. Use an AI-Powered Call Assistant
AI call assistants represent the newest layer of spam call protection. Instead of simply blocking known spam numbers, they actively screen unknown callers in real time.
Aura’s AI Call Assistant works by intercepting calls from numbers not in your contacts. The AI answers on your behalf, asks the caller to identify themselves, and uses natural language understanding to analyze the response for scam patterns. Legitimate calls — deliveries, appointment reminders, real emergencies — get forwarded to you. Spam and scam calls are blocked. A summary of the conversation appears on your lock screen so you never miss something important.
Aura’s call protection supports AT&T, T-Mobile, Verizon, Xfinity, Mint Mobile, Cricket Wireless, Spectrum, Tracfone, and Visible. It also includes SMS protection that scans incoming texts for dangerous links and scam language — relevant since spam texts are part of the same pipeline as spam calls.
Call protection is included with Aura’s Family plan ($25/month) and available as an add-on for Individual ($9/month) and Couple ($17/month) plans. Every plan includes three-bureau credit monitoring, dark web scanning, $1M identity theft insurance, and data broker removal. Full review here.

6. Stop Answering Unknown Numbers
This is the simplest behavior change and one of the most effective. Every time you answer an unknown call, you teach the system that your number is active and monitored by a real person. That intelligence is resold, and your call volume increases.
Let unknown numbers go to voicemail. Legitimate callers — your doctor’s office, your kid’s school, a delivery driver — leave a message. Scammers do not.
7. Block and Report Spam Numbers
When a spam call does get through, block it and report it:
- Block: Open your recent calls, tap the info button next to the number, and select Block.
- Report to carrier: Forward the number to 7726 (SPAM).
- Report to FTC: File at reportfraud.ftc.gov or donotcall.gov.
Individual blocks do not stop the operation, but aggregated reports build the databases that carrier filters and FTC enforcement actions rely on. The more reports filed, the faster spam numbers get flagged across the entire network.
What Doesn’t Work (Save Your Time)
Answering to tell them off. Satisfying in the moment. Counterproductive in practice. Any engagement confirms your number is active.
Pressing “1 to be removed.” This never removes you from anything. It confirms you are a live person who listens to the full message and follows instructions — the most valuable signal a robocaller can get.
Calling back unknown numbers. Some spam calls use one-ring “Wangiri” fraud — they ring once and hang up, hoping you call back a premium-rate number. Even if the number is not premium-rate, calling back confirms your number is active.
Relying on a single tool. No single app, filter, or registry stops all spam calls. The Do Not Call list misses scammers. Carrier filters miss new spoofed numbers. Phone settings miss calls that bypass VoIP detection. The solution is layered — address the source (data brokers), filter what gets through (carrier + phone + AI), and change your behavior (stop answering unknowns).
FAQ
How do I stop spam calls on my iPhone?
Go to Settings → Phone → Silence Unknown Callers. This sends calls from numbers not in your contacts directly to voicemail. Combine this with your carrier’s free spam filter (T-Mobile Scam Shield, AT&T ActiveArmor, or Verizon Call Filter) and data broker removal to address the root cause. Carrier filters block known spam numbers at the network level, while data broker removal cuts off the supply of your number to new robocall operations.
How do I stop spam calls on Android?
On Google Pixel, enable Call Screen in the Phone app — it uses Google Assistant to screen unknown callers automatically. On Samsung, activate Smart Call through Phone Settings → Caller ID and Spam Protection. All Android phones with Google Phone can toggle Filter Spam Calls in Settings → Caller ID and Spam. Add your carrier’s free spam filter for a second layer of network-level blocking.
Does the Do Not Call Registry actually work?
It works against legitimate telemarketers — they face fines up to $51,744 per violation. It does not work against scammers and robocallers, who are already operating illegally and ignore the registry entirely. In testing, the Do Not Call Registry reduced spam call volume by approximately 12%. It is worth doing but should not be your only measure.
Why am I suddenly getting so many spam calls?
A sudden spike usually means your phone number was recently exposed — through a data breach, a new data broker listing, or a form submission that sold your information to lead buyers. When a data broker adds your number, it becomes available to thousands of robocall operations simultaneously. Check haveibeenpwned.com for recent breaches, and search your phone number in quotes on Google to see which broker sites list it.
What is the best spam call blocker app?
Carrier-provided filters (free) are the best first layer: T-Mobile Scam Shield, AT&T ActiveArmor, Verizon Call Filter. For AI-powered screening, Aura’s Call Assistant answers unknown calls on your behalf and uses natural language understanding to detect scam scripts — forwarding only legitimate calls. Third-party apps like RoboKiller and Truecaller provide additional blocking but may flag legitimate VoIP calls from medical offices and delivery services.
Are spam calls dangerous?
Most spam calls are annoying but not directly harmful if you do not engage. The danger is in what happens when you do. Answering confirms your number is active, which increases future call volume. Engaging with a scammer can lead to identity theft, financial fraud, or malware installation. Americans lost $1.1 billion to phone scams in 2025, with an average loss of $3,690 per victim.
Can I sue for spam calls?
Yes. The Telephone Consumer Protection Act (TCPA) allows private lawsuits for unauthorized robocalls and texts. Statutory damages are $500 per violation, increasing to $1,500 for willful violations. You need to document the calls — date, time, number, content — and confirm your number is on the Do Not Call Registry. Class action lawsuits against serial violators have resulted in settlements exceeding $100 million.
