National Insurance numbers
This guide explains how to ask users to give you their National Insurance number.
Meeting the Digital Service Standard

Read the guide on using, adapting and creating patterns before you start designing or building anything.
You shouldn’t use National Insurance numbers to verify a user’s identity. Find out how to protect your service against fraud if you currently use National Insurance numbers to verify identity.

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 ‘AB 12 34 56 C’ as an example (it belongs to a real person) - use ‘QQ 12 34 56 C’ instead
