If you lose or forget your National Insurance number, you can find it in several ways. First, try locating the number on documents like your tax return, payslip, or P60. Alternatively, use your personal tax account or the HMRC App to find your National Insurance number.

If you still can’t find your National Insurance number, submit a written request to HMRC using form CA5403 or call them. HMRC won’t disclose your number over the phone but will send the details by post to your address on file. You should receive the details within 15 days.

HMRC automatically sends teenagers a letter detailing their National Insurance number just before their 16th birthday. Keep these letters in a safe place. Note that HMRC no longer issues plastic National Insurance cards.

The National Insurance number helpline assists those aged between 16 and 20 who haven’t received a letter with their National Insurance number details, as well as other new applicants.

To apply for a National Insurance number, an individual must have the right to work or study in the UK.

Remember, safeguarding your National Insurance number is crucial. It’s not just an identifier, but a key to many aspects of your financial life in the UK. Stay organized, stay secure.
