The calls scammers make most.

Scam callers follow predictable playbooks. Here's what each one looks like — and how to spot them before you answer.

IRS & Government Imposters

Callers claiming you owe back taxes, have a warrant, or must verify your Social Security number immediately.

Tech Support Fraud

"Your computer has a virus." Callers posing as Microsoft, Apple, or your internet provider asking for remote access.

Grandparent Scams

Callers pretending a grandchild is in legal trouble and needs bail money wired immediately — don't tell the parents.

Prize & Lottery Scams

"You've won — just pay the processing fee." You can't win something you didn't enter.

Bank & Credit Card Fraud

Callers claiming suspicious activity on your account, asking you to "confirm" your card number or PIN to stop a transaction.

Robocalls & Neighbor Spoofing

Automated calls using a local area code to seem familiar. Often the opener for a live scammer once you answer.

What to do after you check.

If our checker flags the number — or your gut already did — here's the right sequence.

1
Don't call back

Calling an unknown suspicious number confirms it's active and can trigger more scam attempts. Don't engage.

2
Block the number

Use your phone's built-in blocking feature. On iPhone: tap the number → scroll down → Block this Caller. On Android: tap the three dots → Block.

3
Report to the FTC

File a report at reportfraud.ftc.gov — it helps authorities identify patterns and shut down operations. Takes 2 minutes.

4
Forward scam texts to 7726 (SPAM)

All major US carriers monitor 7726. Forwarding suspicious texts helps block the number across networks automatically.

5
If you shared financial info — act immediately

Call your bank directly using the number on the back of your card. Freeze your credit at annualcreditreport.com. File an identity theft report at identitytheft.gov.

What people ask before they check.

Yes. Per our Security Policy Framework §3.1, the phone number you submit is never stored, logged, or shared. It is used solely to generate your result and discarded immediately after. We have no way to connect a phone number to you personally, and we don't try.
Any format — with or without country code, dashes, spaces, or parentheses. US numbers, international numbers, and toll-free numbers all work. Enter it exactly as it appeared on your phone.
Yes — this is called spoofing. Scammers can make a call appear to come from your bank's real number, a government agency, or even a local number you recognize. If something about the call felt wrong, check it regardless of what the number looked like. Caller ID alone is not proof of legitimacy.
A clean result means we found no known scam activity linked to that number — not that it's definitively safe. Brand new scam numbers won't yet appear in databases. Always combine our result with your own judgment. If the call felt off, trust that instinct.
No. Calling back a suspicious number confirms it's active and can lead to more calls, or connect you to a live scammer. If you believe the call may have been from a real institution, find their official number independently — from their website, a card, or a statement — and call that instead.
The fastest way to check if a phone number is linked to scam activity is to run it through an AI-powered phone number checker before calling back or engaging. Scamanot's Phone Number Checker cross-references the number against known fraud patterns and scam activity databases, returning a clear risk assessment in seconds. Enter the number exactly as it appeared — with or without country code — and get a plain-English verdict with no account required.
Yes — this is called caller ID spoofing, and it is one of the most widely used tactics in modern phone fraud. Scammers can make a call appear to come from your bank, the IRS, a local number, or even a family member's phone. Caller ID alone is never proof that a call is legitimate. If something about the call felt wrong regardless of the number displayed, paste the number into Scamanot's Phone Number Checker — and if they left a message, run that through the Scam Text Analyzer as well.
If you answered a scam call but didn't provide any personal information, the risk is relatively low — but the number now knows your line is active, which may trigger more attempts. Hang up immediately without pressing any numbers, block the number, and report it to the FTC at reportfraud.ftc.gov. If you did share financial information, contact your bank immediately using the number on the back of your card and consider placing a credit freeze at annualcreditreport.com.
This technique is called neighbor spoofing — scammers deliberately display a number with your local area code because people are significantly more likely to answer calls that appear to be from nearby. It creates a false sense of familiarity and lowers your guard before you've heard a single word. A local area code means nothing about where the call actually originated or whether it's legitimate. Always check an unfamiliar number before calling back, regardless of how familiar it looks.
Grandparent scams and Social Security impersonation calls remain the most frequently reported phone scams targeting older adults in 2026. In a grandparent scam, the caller poses as a grandchild or a lawyer claiming the grandchild is in legal trouble and needs money wired immediately — and instructs the target not to tell other family members. Social Security scams involve callers claiming your number has been "suspended" due to suspicious activity. Both rely on fear and urgency to prevent the target from pausing to verify. If you or someone you know receives a call like this, check the number immediately and call the family member directly on a known number before taking any action.
Register your number at donotcall.gov — while it won't stop all scam calls, it reduces legitimate telemarketing and makes unsolicited calls easier to identify as suspicious. Enable your carrier's built-in spam protection (available on all major US carriers at no cost), and consider call-screening apps that flag known scam numbers before your phone rings. When an unfamiliar number does get through, Scamanot's Phone Number Checker gives you an instant risk assessment before you decide whether to engage or block.
