National Insurance Scam

This scam usually arrives as an automated phone call or a message claiming your National Insurance number has been compromised or suspended because of suspected fraud. It pressures you to press a button to speak to an operator or to call a number back, then tries to get personal details or a payment to fix the supposed problem. The threat is designed to frighten you into acting fast. In reality a National Insurance number is a permanent reference that cannot simply be suspended or cancelled by a phone call, and genuine bodies do not deal with such matters through automated threats demanding immediate payment or personal information.

Frequently asked questions

Can a National Insurance number really be suspended?
No. A National Insurance number is a permanent personal reference and cannot simply be suspended, blocked, or cancelled by a phone call. Messages claiming otherwise are commonly used in scams to frighten people into pressing a button, calling back, or handing over personal and financial details.
How do genuine government bodies contact me about this?
Official bodies use established channels and do not typically rely on automated calls that threaten arrest unless you act immediately. They will not pressure you into pressing a button to share personal details or pay on the spot. If you are unsure, contact the body directly using its official details.
I pressed a button or called the number. What should I do?
End the call and avoid sharing any details. If you have already given bank or card information, contact your bank promptly. If you shared personal information, follow your country's guidance on identity theft, monitor your accounts, and report the incident to your national fraud service.
Why are these calls so often automated?
Automated calls let scammers reach large numbers of people cheaply and screen for those who respond by pressing a button. The recorded threat is designed to create fear and urgency. Simply hanging up and not interacting is the safest response, and you can verify any real concern separately.
