Finding your National Insurance number (NIN) in the UK is essential for various reasons, including employment, tax contributions, and accessing benefits. This unique identifier ensures that your National Insurance contributions and taxes are accurately recorded against your name. If you have lost your NIN, there are several straightforward methods to retrieve it.
Your National Insurance number typically consists of two letters, six digits, and a final letter (e.g., AB123456C). Most individuals receive their NIN automatically shortly before their 16th birthday if they are UK residents. However, if you have moved to the UK or have never been issued one, you will need to apply for it.

Where to Find Your National Insurance Number
There are multiple ways to locate your National Insurance number. Here are the most common methods:
- On Documents: Check any official documents you may have received from HMRC or your employer. This includes payslips, P60 forms, and letters regarding tax or benefits. Your NIN is often printed on these documents.
- Online Access: If you have registered for a personal tax account with HMRC, you can log in to view your NIN. The HMRC app also allows you to access this information easily.
- Digital Wallets: If you’ve previously saved your NIN in a digital wallet (like Apple Wallet or Google Wallet), you can retrieve it from there.
- HMRC App: Download the HMRC app on your smartphone. Once logged in, you can view and download a letter confirming your NIN.
If these methods do not yield results, there are alternative approaches to consider.
Alternative Methods to Retrieve Your National Insurance Number
If you cannot find your NIN using the methods mentioned above, here are additional steps you can take:
- Form CA5403: You can fill out form CA5403 online and submit it to HMRC. This form requests confirmation of your NIN and can be sent by post. Make sure to include two forms of identification as specified on the form.
- Contacting HMRC: If you’re still unable to find your NIN, contact the National Insurance helpline at 0300 200 3500. Be aware that while they can assist with inquiries, they will not provide your NIN over the phone; it will be mailed to you instead.
- Identity Verification: When using online services or contacting HMRC, be prepared to verify your identity. This may involve providing personal details such as your full name, address, and date of birth.
Applying for a New National Insurance Number
