National Insurance Numbers (NINOs): Format and Security: Not entitled to a NINO

Not everyone who wants a NINo will get one. Some people do not fall into the category of needing a NINo, including:

  • people over pension age who are neither:

    • working, nor
    • claiming benefit, credits or tax credits, or need one for other HMRC/DWP purposes
  • children under age 16.

For reasons why people need a NINO, see NIM39125.

For legislation see NIM39330.
