Lost My National Insurance Card

Lost My National Insurance Card

Call HMRC on 0843 596 4156 for help if you lose your National Insurance card.

Every eligible UK citizen receives a National Insurance number when they are 16 years old. This is made of 2 letters, 6 numbers, and 1 more letter. A National Insurance number is necessary to apply for benefits, higher education and student loans, employment, pensions, and voting. HMRC sends each citizen a letter in the post around 3 months before their 16th birthday supplying their National Insurance number. Each person keeps the same number throughout their entire life. Therefore, you need to keep a record of your number and keep it secret to prevent identity fraud. You will sometimes have to provide proof of this number.

How do I get a replacement National Insurance card?

Anyone who reached the age of 16 before July 2011 will have a plastic National Insurance card which came with their letter from HMRC. This card was physical proof of their National Insurance number, so it would not matter if they lost the letter. However, to save almost £1 million per year in costs, HMRC is no longer providing physical National Insurance cards. This means that you cannot apply for a card, and if you lose your original card, then HMRC will not issue a replacement for you. Instead, they will send a regular letter in the post, which can take up to 15 days to arrive. This letter will now be proof of your National Insurance number instead of the card. Keep it safe so that you can find it when you need it.

How do I find my National Insurance number?

If you have lost your National Insurance card and/or your original letter, you do not need to worry too much. It is fairly easy to find your National Insurance number on other documents if you can’t remember it. If you are or have been in employment, then your National Insurance number will be shown on your payslips and P45 forms. If you are or have been in receipt of government benefits, then any letters from the DWP about this will also have your National Insurance number on them. Your number should also be on any documents regarding your taxes or pensions. You might have an online personal tax account. You can check your National Insurance number by logging in on gov.uk or in the app if you have one.

How do I get proof of my National Insurance number?

Any of the documents mentioned above may be acceptable as proof of your National Insurance number, but it will depend on the authority asking for it. Employers, educational institutions, and the DWP may accept different forms of proof. However, the one form of proof that they should always accept is a letter directly from HMRC. This is why you should keep the original letter when you receive it at 16. If you do lose it, or you lose your card and now need a letter with your National Insurance number on it, then you should contact HMRC. Call 0843 596 4156, making sure that you have details such as your address and phone number ready. At first, you can either say “lost National Insurance card” or wait and then press 2. You should then say “yes” or wait and press 1 when it asks if you are calling about yourself. It will then connect you to the next available HMRC agent. They won’t be able to speak to anyone but the individual themselves about a National Insurance number. Nor will they be able to provide your number over the phone. Even if you pass the security questions that the agent will ask you, they cannot tell you what your National Insurance number is. They will arrange for an official letter stating your National Insurance number to be sent to your address within 15 days. If you do have a personal tax account, then you can view, download, send or print off a letter of confirmation with your own National Insurance number on it without having to contact HMRC.
