National Insurance Scam Call UK: The 'Suspended' Lie
A National Insurance number stays with you for life; a call saying it has been "suspended" is not describing a real HMRC or DWP process.
What the National Insurance scam call looks like
This scam is typically an automated robocall claiming your National Insurance number has been suspended, compromised, or used in criminal activity, pressing 1 to speak to an "officer" who then asks you to confirm personal or bank details. An example of the style: This is an automated call regarding your National Insurance number. It has been suspended due to suspicious activity. Press 1 to speak with an officer. A National Insurance number stays the same for life; the claim that it has been "suspended" makes the premise of the call false from the outset.
Warning signs to look for
- The call opens with a recorded message claiming your National Insurance number has been "suspended" or "compromised" — "suspended" is not a status GOV.UK recognises for a National Insurance number.
- You're asked to press a number to be connected to an "officer" or department.
- Once connected, you're asked to "confirm" your National Insurance number, date of birth, or bank details over the phone.
- The call threatens arrest, legal action, or loss of benefits if you don't comply immediately.
- The number displayed looks official, but caller ID can be spoofed to show almost any number — it proves nothing on its own.
- You're told to stay on the line while you take an action, such as visiting your bank or buying vouchers.
How this scam works step by step
An automated call plays a recorded message designed to sound official, claiming a problem with your National Insurance number. Pressing 1 connects you to a live scammer posing as an investigator or officer, who repeats the false claim and creates pressure to resolve it immediately. You're asked to "confirm" identifying details — your National Insurance number, date of birth, address, or bank details — which the scammer either already partly has (sometimes from data breaches) or is trying to collect in full.
Depending on the variant, the call may move toward asking for a payment to "unblock" your number, or simply toward harvesting enough personal data to attempt identity fraud afterwards.
How to check a call like this is genuine
Hang up. Genuine government contact about your National Insurance number does not work this way. GOV.UK says HMRC will not tell you your National Insurance number over the phone or webchat; you can find it through your personal tax account, the HMRC app, documents such as a payslip or P60, or ask HMRC to send it by post. If you're at all concerned, contact HMRC yourself using the number on gov.uk, not any number given during the call, and wait a few minutes before dialling to make sure the original line has genuinely disconnected.
No genuine caller will ask you to "confirm" your full National Insurance number, bank details, or date of birth out of the blue like this.
What to do if you've already given details
If you've shared your National Insurance number, date of birth, or address, treat your details as compromised — monitor your bank accounts and post for anything you don't recognise, and consider a Cifas Protective Registration at cifas.org.uk/pr, which costs £30 for two years and prompts extra checks on your name across participating lenders. If you've shared bank details or made a payment, contact your bank immediately. You do not need to do anything about your actual National Insurance number itself, since it cannot be "suspended" and this part of the call was never true.

Frequently asked questions
Can a National Insurance number actually be suspended?
No. A National Insurance number stays the same for life, and a call claiming it has been suspended or frozen is describing something that does not exist as an official process.
Would HMRC or DWP ever read out or ask me to confirm my National Insurance number by phone?
HMRC says it will not tell you your National Insurance number over the phone or webchat. If you cannot find it through your personal tax account, HMRC app, or documents such as a payslip or P60, you can ask HMRC to send it by post. Being asked to "confirm" it, your date of birth, or bank details on an unexpected call is a warning sign on its own.
I gave my National Insurance number and date of birth on one of these calls — what should I do?
Treat your details as compromised: watch your bank accounts and post closely, and consider registering for a Cifas Protective Registration at cifas.org.uk/pr. If you shared bank details or made any payment, contact your bank immediately. You don't need to take any action regarding your National Insurance number itself, since it can't actually be suspended.
How do I report this scam call?
Report it to Report Fraud at reportfraud.police.uk or 0300 123 2040 (Police Scotland on 101 in Scotland), including the number that called and what was said. Forward any related text to 7726.
