In the UK, if you are employed or looking for work, you must have a National Insurance (NI) number, or have at least applied for one. NI contributions help finance the National Health Service (NHS). By making contributions, you also build up your entitlement to certain social security benefits, including the State Pension.

If you don't already have a NI number you need apply for one:

  • as soon as you start work
  • as soon as you or your partner claims benefit
  • you need it to claim a student loan


Important to know: Anyone who works in the UK is required to have a National Insurance Number.
