Can a phone number be spoofed to look like a government agency?
Yes. Caller ID spoofing allows anyone to display any number, including official government helpline numbers.
Last reviewed: 1 June 2026
Explanation
Caller ID is not a verified identity system. Any phone number — including those belonging to the IRS, Social Security Administration, FBI, police non-emergency lines, or other government agencies — can be spoofed using widely available online services. This means seeing a government number on your screen is not evidence the call is genuine. Government agencies have published guidance emphasising that they will never demand immediate payment, threaten immediate arrest without prior notice, or request payment by unconventional means. If you receive a call from what appears to be a government number, hang up and call the agency back using a number you find on its official website.
Common red flags
- Call from what appears to be an official government number demanding payment
- Caller threatens immediate consequences if you hang up
- Payment demanded by gift card, wire, or crypto
- Caller instructs you not to tell family or an attorney
- Sense of extreme urgency — minutes to comply
What to do now
- Hang up
- Look up the agency's number on its official website and call back to verify
- Report the spoof call to the FTC, FCC (US), or Ofcom (UK)
- Share the experience with people who might be similarly targeted
Frequently asked questions
Does my phone carrier protect me from spoofed calls?
Most major carriers use STIR/SHAKEN call authentication technology that can flag some spoofed calls, but it is not foolproof. Treat any call demanding money or personal information with scepticism regardless of the caller ID.
