Is This Number a Scam? How to Check a Phone Number
Caller ID can be faked, so a number alone can't prove who's calling. Use this checklist to judge a suspicious call or text and find the real number to call.
The telephone is still one of the main ways scammers reach older adults. A caller may pretend to be from the government, your bank, a tech company or a family member in trouble. The number on your screen may even look local or official, because caller ID can be faked.
You never have to stay on the line with someone who calls you unexpectedly. Hang up, look up the real number yourself, and call back. The guides below explain the most common calls, how caller ID spoofing works, and how to report a scam number.

Texts and emails get most of the headlines, but the phone call remains one of the most damaging ways scammers reach older adults. When the FTC studied reports from older adults who lost $10,000 or more in 2024, 41% said the scam started with a phone call. A live voice can build trust, create panic and keep you on the line — and caller ID can be faked to make the call look legitimate.
The FBI’s 2025 Internet Crime Report found that call-center fraud — tech support and government impersonation scams run from illegal call centers — produced more than 80,000 complaints and over $2.9 billion in losses in a single year.
The FTC says nearly every phone scam shows at least one of these signs:
The caller pretends to be someone you trust: a government agency, a family member, a romantic interest, or a company you recognize — like a tech company warning about a computer problem. Caller ID may be faked. Read more:
A panicked “grandchild” needs money for bail or a hospital — now sometimes with a voice copied by AI. Hang up and call your relative back on the number you already have. See AI scams: voice cloning and your family.
Caller: Grandpa? It’s me. Please don’t be mad. I got arrested and I need you to help me with bail.
Caller: Please don’t tell Mom. My public defender will call you in five minutes with instructions. You’ll need to get cash — they said a courier can pick it up today.
You’re told you’ve won — but you have to pay taxes, registration or shipping first. The FTC says the prize doesn’t exist.
Callers use details about your vehicle to sell overpriced or worthless service contracts. Don’t buy anything on the spot.
Callers promise lower credit card rates, credit repair, student loan forgiveness, or guaranteed loans — in exchange for an upfront fee. The FTC says honest lenders don’t guarantee loans or charge “advance fees” like this.
Callers offer business coaching or guaranteed investment profits, often in cryptocurrency. The FTC suggests checking any opportunity with your state securities regulator. See trading scam red flags.
Fake charities ask for donations for disaster relief, police or veterans, or families affected by illness. Ask how much of your gift goes to the mission, and check out the charity before you give.
You’re signed up for a product that bills you every month until you cancel. Read the terms and watch your statements.
Free or cheap vacations that come with fees, or offers to resell your timeshare if you pay first.
Your phone rings once and stops. The FCC warns this can be a trick to get you to call back an international number that charges connection and per-minute fees. Don’t return calls from numbers you don’t recognize.
You don’t owe anyone a conversation. “I’ll call the company myself” — and hanging up — is always the right answer.
The FTC calls call blocking your best defense, because scammers ignore the Do Not Call Registry. Turn on your carrier’s free tools and your phone’s spam filters — step-by-step settings are in how to stop spam texts and calls. Register your number for free at DoNotCall.gov or 1-888-382-1222 (call from the number you want to register) to stop most legitimate telemarketers. And when a call seems suspicious, use our checklist: is this number a scam?
Act fast: the FTC says to contact the company you used to pay — card issuer, bank, wire service (such as Western Union, MoneyGram or Ria), gift card company or payment app — and ask to stop or reverse the payment. If you sent cash by mail, call the U.S. Postal Inspection Service at 877-876-2455. Be wary of anyone who offers to recover your money: that is often a second scam. See the first-hour checklist, then report the call.

Scammers can make any name or number show on caller ID — your bank, a government agency, even your own number. How spoofing works and how to protect yourself.
Guide
Where to report a scam phone number: DoNotCall.gov, ReportFraud.ftc.gov, the FCC and the right agency for IRS, Social Security or Medicare impostor calls.
Reporting helps investigators spot patterns and warn others — even if you did not lose money. Type these addresses yourself or use the links below; do not use links from a suspicious message.
Federal Trade Commission (FTC)
Any scam, fraud or bad business practice — calls, texts, emails, websites and impostors.
National Do Not Call Registry (FTC)
Report an unwanted sales call or robocall when you did not lose money. You can also register your number for free.
Federal Communications Commission (FCC)
Unwanted robocalls, spoofed caller ID and spam texts.
National Elder Fraud Hotline (U.S. Department of Justice)
Free help for people 60 and older: case managers help you report and plan next steps. Mon–Fri, 10 a.m.–6 p.m. Eastern.
You can also report to your state attorney general. If you sent money, call your bank or card company right away using the number on the back of your card.
The FTC lists impostor calls (government, family, romance, tech companies), debt relief and credit repair offers, business and investment pitches, fake charities, extended car warranties, 'free' trials, loan offers, prize and lottery calls, and travel or timeshare deals.
Phone phishing — sometimes called vishing — is when a caller or recording pretends to be a bank, company or government agency to get your personal or financial information. The FCC advises never giving out account numbers, Social Security numbers, passwords or similar information on unexpected calls.
The FCC suggests not answering calls from unknown numbers. Legitimate callers can leave a voicemail. If you do answer and something feels wrong, hang up.
No. The FTC says scammers ignore the registry. It does stop most legitimate telemarketers, and if you're registered, a sales call from a company you haven't done business with is likely illegal. Call blocking is the best defense against scam calls.
As little as possible. Don't answer questions — especially ones that can be answered 'yes' — and don't press any buttons. Just hang up. You never owe a caller an explanation.
If you didn't lose money, use DoNotCall.gov. If you lost money or shared information, report at ReportFraud.ftc.gov and call your bank. Include the caller ID number, any callback number and the time of the call.
