How to Report a Scam Phone Number: Complete 2026 Guide

Scam calls are a global epidemic. In the past year alone, consumers worldwide lost over $55 billion to phone-based fraud, according to industry estimates. Whether it's a fake tax agent threatening arrest, a "grandchild" begging for bail money, or a robocall about your car's expired warranty, scam numbers are flooding our phones at record rates. The good news? You don't have to just hang up and move on. Reporting a scam number is one of the most powerful things you can do to protect yourself and others.

This guide walks you through exactly how to report a scam number to the right authorities, carriers, and platforms — no matter where you live.

Why Reporting Scam Numbers Actually Matters

Reporting a scam number is the process of flagging a suspicious phone number to regulators, carriers, or crowd-sourced databases so it can be investigated, blocked, or added to warning lists. Every report adds data points that help authorities build cases and help call-blocking apps protect millions of people.

Here's what your report can accomplish:

• Trigger investigations: Government agencies use patterns of complaints to identify large-scale fraud operations.
• Improve call-blocking apps: Databases like those used by carriers and third-party apps update in near real-time based on user reports.
• Help prosecutors: Detailed reports can become evidence in criminal cases.
• Protect vulnerable people: Elderly individuals and non-native speakers are disproportionately targeted — your report helps shield them.

Step-by-Step: How to Report a Scam Number

Follow these steps in order. The whole process usually takes less than 10 minutes.

1. Don't delete the call log. You'll need the exact number, date, and time.
2. Write down what happened. Note what the caller said, any names they used, any companies they claimed to represent, and any payment methods they requested (gift cards, wire transfers, cryptocurrency, etc.).
3. Block the number on your phone to prevent repeat contact.
4. Report to your national regulator (see the table below).
5. Report to your mobile carrier so the number can be blocked at the network level.
6. Report to crowd-sourced databases like 800notes, Nomorobo, or Hiya to warn others.
7. If money was lost, file a police report and contact your bank immediately.

Where to Report a Scam Number by Country

Different countries have different agencies responsible for investigating phone scams. Use this table to find the right channel for your region.

Country / Region	Primary Agency	How to Report
United States	FTC & FCC	reportfraud.ftc.gov and consumercomplaints.fcc.gov
United Kingdom	Action Fraud / Ofcom	actionfraud.police.uk or forward texts to 7726
Canada	Canadian Anti-Fraud Centre	antifraudcentre-centreantifraude.ca or call 1-888-495-8501
Australia	Scamwatch (ACCC)	scamwatch.gov.au/report-a-scam
European Union	National consumer authority	europa.eu/youreurope — then local regulator
India	DoT & Cybercrime Portal	sancharsaathi.gov.in or cybercrime.gov.in
New Zealand	CERT NZ	cert.govt.nz/report
Singapore	ScamShield / SPF	scamshield.gov.sg

The Universal Shortcut: 7726 (SPAM)

In many countries — including the US, UK, Canada, and Australia — you can forward spam text messages to the shortcode 7726 (which spells SPAM on a keypad). This sends the message directly to your carrier's fraud team, free of charge. It's the fastest way to report scam SMS messages.

How to Report to Your Mobile Carrier

Your carrier can block scam numbers at the network level, which is far more effective than blocking them on just one device.

Major US Carriers

• Verizon: Use the Call Filter app (free tier available) or report via My Verizon.
• AT&T: Use AT&T ActiveArmor app or report at att.com/activearmor.
• T-Mobile: Use Scam Shield (free) or dial #662# to activate scam blocking.

Major UK Carriers

• EE, Vodafone, O2, Three: All accept SMS forwarding to 7726 and have online fraud reporting forms.

What Carriers Do With Your Report

Once reported, carriers run the number through STIR/SHAKEN authentication frameworks (in the US and Canada) to verify whether the call was spoofed. Confirmed scam numbers are added to network-wide block lists and shared with industry databases.

Using Third-Party Apps and Databases

Beyond official agencies, crowd-sourced apps are often the fastest way to warn others about active scams.

• Hiya: Free scam ID and blocking, used by major carriers.
• Truecaller: Massive global database with 400+ million users — strong in Europe, Africa, and Asia.
• Nomorobo: Blocks robocalls on landlines and mobile.
• RoboKiller: Uses AI to filter and report scams automatically.
• 800notes.com: Free web-based database where users leave comments about suspicious numbers.

Reporting through these apps helps update their algorithms within minutes, protecting other users in real time.

How to Report Specific Types of Phone Scams

Robocalls and Pre-Recorded Messages

In the US, report these to the FCC at consumercomplaints.fcc.gov. Include whether you had given consent to be called (if applicable), as unsolicited robocalls to mobile phones are illegal under the TCPA.

Phishing SMS ("Smishing")

Forward the text to 7726, then delete it. If the message contained a link, do not click it. Scam links often lead to credential-harvesting pages or malware downloads. If you want to safely share a suspicious link with an investigator, use a reputable link management service rather than forwarding the raw URL. Services like Lunyb let you wrap and analyze URLs without exposing yourself to tracking parameters.

Impersonation Scams (IRS, HMRC, CRA, Police)

Government agencies will never demand payment via gift cards, wire transfers, or cryptocurrency. Report impersonation scams directly to the agency being impersonated — the IRS has a dedicated line at phishing@irs.gov, HMRC accepts reports at phishing@hmrc.gov.uk.

Tech Support Scams

Report to your national consumer protection agency and also to Microsoft (microsoft.com/reportascam) or Apple if the scammer impersonated a specific tech company.

Romance and Investment Scams

These often start on dating apps or social media but move to phone calls. Report the phone number to your national agency and the originating platform (Meta, Tinder, Bumble, etc.).

What Information to Include in Your Report

A detailed report is more useful than a quick one. Try to include:

• The scammer's phone number (even if spoofed)
• Date and time of the call
• What was said and any transcript you can recall
• Company or agency the caller claimed to represent
• Any names, callback numbers, or websites mentioned
• Payment methods or personal data requested
• Whether you lost money and how much
• Your location at the time of the call

What to Do If You Already Gave Information or Money

If you've already engaged with a scammer, speed matters. Follow these steps immediately:

1. Contact your bank or card issuer and request a fraud freeze and chargeback.
2. Change passwords on any accounts where you shared credentials. Enable two-factor authentication.
3. Place a fraud alert with credit bureaus (Equifax, Experian, TransUnion in North America; Equifax and Experian in the UK).
4. File a police report — you'll need this for insurance claims and chargeback disputes.
5. Report to your national cybercrime agency.
6. Monitor your accounts and credit reports for at least 12 months.

How to Reduce Scam Calls Going Forward

Reporting is reactive. Prevention is proactive. Here's how to cut down on scam calls in the first place:

• Register with your national Do Not Call list (donotcall.gov in the US, tpsonline.org.uk in the UK).
• Enable carrier-level scam blocking (free from all major carriers).
• Use silence unknown callers settings available on iOS and Android.
• Don't publish your phone number on social media or public websites.
• Use burner or secondary numbers (Google Voice, Hushed, MySudo) for signups and online forms.
• Be skeptical of urgency — legitimate organizations don't demand immediate payment over the phone.
• Protect your digital footprint. The less data brokers know about you, the fewer calls you'll get. Review privacy settings on social platforms and consider opting out of data broker sites through services like DeleteMe or Incogni.

Common Myths About Reporting Scam Numbers

"They'll just spoof a new number, so reporting is pointless."

Partly true, but still worth doing. While many scammers spoof numbers, patterns in reports help agencies trace the actual infrastructure behind the calls — often VoIP providers or overseas call centers that can be shut down.

"Reporting takes too long."

Most reports take under five minutes. Forwarding a text to 7726 takes under 30 seconds.

"Nothing ever happens."

Enforcement actions have resulted in billions in fines against illegal robocallers and the shutdown of major scam operations. Collective reporting drives this.

Frequently Asked Questions

Can I report a scam number anonymously?

Yes. Most national agencies (FTC, Action Fraud, Scamwatch) allow fully anonymous reports. However, providing contact details helps investigators follow up if they need more information or if your case becomes part of a larger prosecution.

What happens after I report a scam number?

Your report is added to a database used by law enforcement, carriers, and call-blocking services. Individual reports rarely trigger immediate action, but clusters of reports about the same number or scam pattern can lead to investigations, carrier-wide blocks, and sometimes criminal charges.

Should I call the scam number back to confirm it's fake?

No. Calling back can confirm your number is active, resulting in more scam calls. It can also connect you to premium-rate numbers that charge high fees. If you need to verify a company is legitimate, look up their official number independently and call that instead.

Can I report international scam numbers?

Yes. Report them to your own country's agency — they coordinate internationally through bodies like the Global Anti-Scam Alliance (GASA) and Interpol. You can also report to the country of origin if known.

Is it illegal to receive a scam call?

No — receiving the call is not illegal, and you've done nothing wrong by answering. The crime is on the scammer's side. Reporting helps bring them to justice without any risk to you.

Final Thoughts

Reporting a scam number takes just a few minutes, but the collective impact is enormous. Every report feeds into systems that protect millions of people — from elderly parents who might fall for a Medicare scam to young workers targeted by fake job offers. Make it a habit: when a scam call comes in, don't just hang up and forget. Take two minutes to report it. Your future self — and plenty of strangers you'll never meet — will thank you.
