This guide explains how to ask users to give you their National Insurance number.

Meeting the Digital Service Standard

To pass point 13 (make the user experience consistent with GOV.UK) in your service assessments, you must use GOV.UK design patterns and guidance.

Read the guide on using, adapting and creating patterns before you start designing or building anything.

Use a single text field

Use a single text field labelled ‘National Insurance number’, like this:


You should also:

  • allow for 13 characters - National Insurance numbers are often spaced in pairs
  • avoid using ‘NINO’ or ‘NI number’ as the label
  • avoid using ‘AB 12 34 56 C’ as an example (it belongs to a real person) - use ‘QQ 12 34 56 C’ instead

Discuss National Insurance numbers

Discuss National Insurance numbers on the design patterns wiki.
