Scammers Can Spoof an Official Phone Number
Scammers Can Spoof an Official Phone Number
What Is Phone Number Spoofing?
Phone number spoofing is when a scammer fakes the caller ID on your phone so it appears that the call is coming from a trusted source, like a bank, government agency, tech support, or even your own number.
They use software or VoIP tools to manipulate the number that shows up on your phone. That’s why victims often say:
“But it was the real number from the back of my card!”
In reality, it was spoofed to appear that way.
Why scammers love spoofing
- Instant credibility: People trust familiar numbers and local area codes.
- Bypasses basic checks: Many victims verify the number on Google or their card and assume the call is legit.
- Pairs well with urgency: Threats (tax debt, account lock), payment pressure, or OTP requests land harder when the Caller ID looks “official.”
Where spoofing shows up in real scams
- Bank security: “We detected fraud; read me the code we just sent so we can stop the transfer.” (They’re stealing your 2FA.)
- Government/tax: “There’s a warrant/arrest risk unless you pay immediately.”
- Delivery: “Redelivery fee—please confirm your card details.”
- Tech support: “We’re from Microsoft/Apple; your device is infected. Install this remote tool.”
- Telco: “SIM upgrade required. We’ll text a code—tell me the digits to proceed.” (SIM-swap setup.)
Why Is This So Dangerous?
Spoofing preys on trust. Most of us glance at the caller ID and assume it’s legit, especially if it’s a known number.
Once the scammer has your attention, they may:
- Demand urgent payment
- Ask for 2FA codes or passwords
- Trick you into installing remote access software
- Pressure you to send cryptocurrency or gift cards
By spoofing an official number, they bypass your internal alarm system.
How Common Is Spoofing in 2025?
Extremely. According to ACMA, phone scams accounted for over $136 million in losses in Australia in 2024, with spoofing being one of the top vectors. In the US, the FTC received over 3.4 million fraud reports, many involving spoofed calls.
And now with AI-powered voice cloning, scammers don’t just fake the number, they fake the person too.
Real Spoofing Scenarios Happening Right Now
AU ACCC Number Spoofed
Scammers are calling Australians using the real ACCC number, threatening victims with fines or arrest unless they pay.
US Jury Duty Scams
Victims across the US have reported receiving calls from spoofed court numbers. The scammer claims the person missed jury duty and must pay a fine immediately.
“Your Bank Called,” But It Wasn’t
One woman lost $38,000 after receiving a call from what looked like her bank. The scammer told her someone was accessing her account and got her to “secure” her funds in their wallet.
AI Voice Spoofing
New scams involve cloned voices; the call sounds exactly like your boss, your son, or a government agent. It’s eerily convincing.
How Do Scammers Spoof Numbers?
They use:
- VoIP Services: Internet-based calling lets users enter any number to display.
- Caller ID Manipulation Software: Easily purchased online.
- Prepaid Calling Platforms: Some allow ID spoofing via a PIN.
- AI Voice Cloning Tools: Fake a person’s voice to add believability.
Why Spoofing Is Getting Worse in 2025
- AI Makes It Easy: Voice cloning is now a low-cost tool anyone can use.
- Global Call Centers: Organised scam rings operate full-time across borders.
- Crypto = Easy Payout: Scammers push for crypto payments that are harder to trace.
- Trust in Caller ID: Most people still assume caller ID is safe it’s not.
Red Flags That a Call Is Spoofed
- You weren’t expecting the call
- The number matches a legit one, but the call content feels off
- They want money fast
- They ask for sensitive info like passwords, card numbers, or 2FA codes
- They don’t let you hang up and call back
- They say things like “Don’t trust anyone else at the bank.”
What To Do If You Get a Suspicious Call
- Hang up immediately
- Do not press buttons or interact with auto-menus
- Do not share personal or financial info
- Google the number, see if it’s linked to fraud
- Call the real organisation yourself
- Report the scam to the authorities and your financial institution

How To Protect Yourself Long-Term
Enable Caller ID Verification (STIR/SHAKEN)
Ask your telecom provider if they support STIR/SHAKEN, a US protocol that helps identify spoofed calls. Australia is rolling out similar tech.
Use Scam Alert Tools
- Apps like Hiya, Truecaller, or your telco’s scam filter (like Telstra’s Scam Block) can help identify known scam numbers.
- Block International or Unknown Numbers
- If you don’t receive legitimate international calls, consider blocking them.
- Set Up Bank and Email Alerts
- Real-time alerts help you spot fraud the moment it happens.
- Educate Elderly or Vulnerable Friends
- They’re often prime targets. Teach them not to trust caller ID.
Is Spoofing Illegal?
Yes. In both the US and Australia:
- US: Under the Truth in Caller ID Act, spoofing is illegal when used to defraud. Fines can exceed $1 million.
- AU: The Scams Code of Practice and Scam Prevention Bill 2025 require telcos to block known spoofing attempts and share intelligence with authorities.
But enforcement is tricky, scammers operate from overseas, change numbers often, and hide behind encryption.
