National Insurance Manual

National Insurance Numbers (NINOs): Registration of a new NINO: Juvenile Registration: the automatic process

Most people are automatically given a National Insurance Number as they approach the age of sixteen. This is because when a claim to Child Benefit is made, the child is allocated a Child Reference Number (CRN) for HMRC/DWP use only. From the child reaching age fifteen years and nine months, HMRC notifies each child of their NINO.

However, special action needs to be taken for:

  • Children who are being looked after by Social Services, see NIM39310
  • Other cases excluded from the automatic process, see NIM39325.
