Is This a Scam Number? How to Judge the Call

The number on your screen cannot answer that. The call itself can. Here is how to weigh both, and what to do next.

You are staring at your caller ID and asking one thing: is this a scam number? Here is the honest answer. The number alone cannot prove it either way. The FCC says you may not be able to tell right away if an incoming call is spoofed. What you can do is judge the call itself. This page walks you through that.

Why the number on your caller ID cannot tell you if it is a scam

Scammers can fake what shows on your screen. The FCC calls this spoofing, which is when a caller deliberately falsifies the information sent to your caller ID display to disguise their identity. The FTC says the same thing in plainer words: a scammer can make a fake name or number show up on your caller ID.

Two tricks are common. The FCC says scammers often use neighbor spoofing, so an incoming call appears to come from a local number. That call that looks like your area code may not be your neighbor. The FCC also says scammers may spoof a number from a company or a government agency you may already know and trust. So a familiar name on the screen proves nothing either.

Even the labels can mislead. The FCC says a number labeled as a potential scam or spam on your caller ID may have been spoofed. A label is a hint, not a verdict.

Warning signs in the call itself

Since the number cannot answer your question, listen to the call instead. The FTC says scammers have many ways to cheat people over the phone. They want your money, or your personal information to commit identity theft.

Watch for these signs.

Pressure to act now. The FCC says to use caution if you are being pressed for information immediately. The FTC says most honest businesses will give you time to think an offer over and get written information first.
A demand for payment by wire transfer, gift card, cryptocurrency, or payment app. The FTC says only scammers insist on those methods.
Threats. The FTC says real law enforcement and federal agencies will not call and threaten you. A threatening caller is not the real thing.
Questions about your Social Security number or other sensitive details. The FTC says no government agency will call you out of the blue and ask for sensitive information like that.
A fee before a prize. The FTC says if you have to pay to get a prize, it is not a prize.
Requests for your username or password. The FBI says companies generally do not contact you to ask for these.
Odd tone. The FTC says some phone scammers act friendly and helpful while others threaten or try to scare you. Neither mood means the caller is real.

The FCC says to be extremely careful about responding to any request for personal identifying information. That rule holds no matter who the caller claims to be.

How to check a phone number safely

If the caller claims to be from a company, do not use the number they gave you. The FBI says to look up the company's phone number on your own and call the company to ask if a request is legitimate.

If you want a broader picture of how these calls operate, our page on phone number scam tactics covers the common scripts.

One more caution. The FCC says scammers who reach you use scam scripts to try to steal your money or valuable personal information.

What to do if you answered or called back

First, do not panic. Answering a call is not the same as losing money. The FTC says not to give phone scammers your money or personal information.

Still, be careful about what you say. The FCC says not to respond to any questions, especially those that can be answered with yes or no. The FCC says scammers often use this button trick to identify potential targets. Pressing keys when a recording asks you to can mark you as someone who picks up.

The FCC says not to answer calls from unknown numbers, and if you answer such a call, hang up immediately. If you already answered and the caller asked for money or information, hang up now and do the lookup step above.

If you gave out information or money, treat this as a possible identity theft situation. The same caution applies to any link they sent you. Our guide to checking is this a scam website can help there.

How to report a scam number

Reporting helps even when the number is fake. The FTC says to report a call even if you think the number on your caller ID is fake. Here is where each report goes.

If you lost money or have information about the scammer, the FTC says to tell the FTC at ReportFraud.ftc.gov.
If you did not lose money and just want to report a call, the FTC says to use the streamlined reporting form at DoNotCall.gov.
If you think you have been the victim of a spoofing scam, the FCC says you can file a complaint with the FCC.

The FTC says to report the exact date and time of the call if you know it. Your report matters more than you might think. The FTC releases the phone numbers you report to the public each business day. Those numbers help phone companies and other partners working on call-blocking and call-labeling solutions. The FTC says any information you provide will help stop the scammers.

How to block scam calls going forward

The FTC says your best defense against unwanted calls is call blocking and call labeling. Here is what that looks like in practice.

Ask your phone company. The FCC says to talk to your phone company about call blocking tools and check into apps you can download to your mobile device. The FTC says some phone provider services are free, but others might charge you a fee.
Try a call-blocking app. The FCC says phone companies and app developers offer call-blocking and labeling services that detect likely fraudulent calls. The FTC says some call-blocking apps are free, but others charge a fee. Apps usually let you choose how to respond to calls they flag as scams. They also let you create lists of numbers to block or let through.
Check the privacy policy first. The FTC says some apps access your contacts list, so know whether that matters to you. An app's privacy policy should explain how it gets and uses your information.
Consider a white list service. The FCC says carriers can offer white list services that block calls from numbers not on your contact list or a list you supply.
Protect your voicemail. The FCC says to set a password for your voice mail account with your phone service. It also says to check your voicemail periodically so you do not miss important calls.

The FTC says to go to the Federal Communications Commission's Call Blocking Resources for links to company-specific information about blocking calls. If you are not sure what phone service you have, the FTC says to check with your phone provider.

Two cautions. The FTC says call-blocking services might block some calls you want to get, so check what a service blocks before you rely on it. And the FTC says being on the National Do Not Call Registry will not stop scammers from making illegal calls. It could reduce the number of calls you get and make it easier to spot scam calls, but it is not a shield.

If your own number shows up on other people's caller ID

One last case. The FCC says if people tell you your number is showing up on their caller ID, it is likely your number has been spoofed. You did nothing wrong, and you are not alone.

There is some good news. The FCC says scammers who use spoofed numbers switch numbers often and may stop using your number within hours. In the meantime, the FCC says you can place a message on your voicemail letting callers know that your number is being spoofed.

So, is this a scam number? The screen cannot say. The call can. Judge the caller by what they ask for, verify companies on your own, and report what you see.
