A National Insurance number is a unique identification number used by the UK government to keep track of an individual’s National Insurance contributions. National Insurance contributions are a type of tax that is used to fund the UK’s welfare system, including benefits such as the State Pension, Jobseeker’s Allowance, and Child Benefit. Everyone who works in the UK, or who receives a State Pension or other benefits, must have a National Insurance number.
There are a number of different ways to apply for a National Insurance number. The most common way is to apply online through the government’s website. You can also apply by post by completing a form and sending it to the National Insurance Contributions Office. If you are unable to apply online or by post, you can also apply in person at a Jobcentre Plus office.
