The National Insurance Number is recorded in the Personal Details section of the fact find, under the About You group.
Where to enter the National Insurance Number
Open the relevant case.
In the left-hand navigation bar, click Personal Details.
Locate the National Insurance Number field within the form.
Enter the number and click Save.
Format requirements
The National Insurance Number must follow the standard UK format:
Two prefix letters, six digits, and one suffix letter (e.g. JG103759A).
The suffix letter must be A, B, C, or D.
Certain letter combinations are not valid as prefixes (e.g. BG, GB, KN, NK, NT, TN, ZZ, and prefixes beginning with D, F, I, Q, U, or V).
Do not include spaces.
If the number entered does not match the required format, a validation error will appear and you will need to correct it before saving.
Why is this needed?
Lenders typically require the National Insurance Number as part of identity verification and to check the applicant's credit history. Providing it accurately in the fact find avoids delays during the application process.
