Ever answered a call, only to hear a sketchy robot offering a free vacation – or worse, pretending to be your bank? You’re not alone. The survey found that 96.8% of people have been hit with scam messages. Nearly half (49%) got them via SMS, and 26.5% through calls.
Scammers often use phone number spoofing to fake their caller ID, making it look like the call is coming from a trusted source. It could appear to be a local business, a government agency – or even your own number.
But here’s the good news: You can fight back. If you know how to tell if a phone number is spoofed, you can dodge scams before they waste your time (or your money). In this guide, we’ll show you how to uncover who’s calling and block them for good. Let’s shut these scammers down.
What Is Caller ID Spoofing?
Scammers aren’t just sketchy individuals calling from random blocked numbers anymore. These days, some of them run full-blown “businesses” – complete with customer service scripts, deepfake voices, and fake official hotlines. They’ve turned fraud into a profession, and the worst part? It’s getting harder to tell what’s real and what’s not.
Caller ID spoofing is one of their sneakiest tricks. It lets them fake a phone number to look like someone you trust – your bank, a government agency, or even a family member. They don’t just want you to answer; they want you to trust them.
Why is spoofing so dangerous? These calls aren’t just annoying. They can wreck lives. Here’s how:
- Stealing your identity – They pretend to be your bank, tricking you into handing over personal info.
- Draining your money – Fake fraud alerts convince people to “transfer” their savings for “security reasons”.
- Grabbing personal info – They fish for Social Security numbers, passwords, and home addresses.
- Tricking kids – Some scammers target kids, getting them to reveal private family details.
- Scamming elderly parents – Fake “Grandma, I’m in trouble” calls pressure seniors into wiring money fast.
So, what should you do? Simple – don’t pick up. If it’s important, they’ll leave a voicemail. If you’re unsure, learn how to tell if a phone number is spoofed before calling back. And if you’re wondering how to stop someone from spoofing my phone number, stick around.
How to Spot a Fake Call: Key Signs

Scammers are slick, but their calls usually have tell-tale signs. If a call feels off, trust your gut. Here’s how to tell if a phone number is spoofed before you waste a second on it.
Red flags to watch for:
- Weird or unexpected numbers – Calls from strange area codes, international numbers, or numbers that look suspiciously similar to yours? Red flag.
- High-pressure tactics – If they demand you act right now – pay a bill, confirm info, or claim a prize – it’s likely a scam. Legit businesses don’t rush you.
- Vague or suspicious answers – Ask them who they are and why they’re calling. If they dodge the question or get aggressive, hang up.
- Robocalls & prerecorded messages – Banks and government agencies rarely use robotic voices for real issues.
- The caller ID doesn’t match the story – They claim to be from your bank, but the number looks random? Don’t trust it.
- No voicemail, no callback – Scammers rarely leave voicemails, and if you try calling back, the number might not even work.
- If it’s flagged as spam, you’ve got your answer – Do a reverse phone lookup online. If others have reported it, you know what to do – block it.
How to Uncover a Spoofed Number?
Got a weird call? Something about it just feels… off? Maybe the number looks local, but the voice doesn’t match. Maybe they’re rushing you to act fast. Or maybe your gut is just screaming “scam alert!” (good instinct). Here’s how to uncover a spoofed number and outsmart whoever’s on the other end.

Dial 69 to Check Who Called Last

How to do it:

Dial 57 to Trace Harassing Calls

- Write down the time, date, and anything suspicious about the call.
Heads up: Some phone carriers charge extra for this service, so check first.
Other Tricks
If you’re unsure about a suspicious call, try calling the number back from a different phone. A spoofed number often results in a “number not in service” message. You can also check online scam databases to see if others have flagged the same number, using sites like Scamwatcher. Many apps are designed to track spam calls, so use those to verify if the number has a bad reputation. These simple steps can save you time and help you avoid falling for a scam.
How Your Carrier and the Authorities Can Help You Fight Spoofed Calls
You don’t have to fight spoofers alone. Your carrier is no stranger to spam calls – they deal with them daily. While they can’t magically reveal the mystery caller every time, they can help trace a spoofed phone number, block future calls, and give you some peace of mind.
Here’s how to get the most out of your phone provider:
- Gather the info – Before you call, write down as much detail as you can. Dates, times, and any recurring numbers. The more specifics, the better.
- Ask about tracing the call – See if your provider can help you identify the caller or at least tell you where the call came from. Sometimes, they can see if the number was spoofed. This info could be useful if you need to involve law enforcement.
- Inquire about extra security features – Some providers have call-blocking options, spam filters, or even call rejection features. Ask about what’s available to you, and turn them on to reduce your chances of getting another scam call.
If things have gone beyond annoying, and the scammer has crossed into harassment or threats, you might consider reporting it to the authorities. Law enforcement has tools that can help track down these fraudsters and put a stop to it.
Who to contact:
- FCC (Federal Communications Commission) – In the U.S., the FCC handles phone fraud, and they can even fine scammers if they catch them.
- FTC (Federal Trade Commission) – If it’s a scam, you can report it at reportfraud.ftc.gov.
- Your local police – For serious cases, like threats or identity theft, file a police report.
