NINO

If you want to ask for someone’s National Insurance Number (NINO) you can select this type and the question will automatically have built-in validation that corresponds to the rules about the format of National Insurance Numbers:

Note that you can choose to display the NINO as a single entry box or by unchecking 'Display a single line field instead of 5 separate fields'.

When this is unchecked we can see, in the screen show below:

NINO - 5 field design pattern

That:

1. the format of the input fields reflects the expected format of a NINO

2. It validates the data entered and where it does not conform to the expected format an error is presented.
