About National Insurance Number (NINO)
The National Insurance Number (NINO) is a unique 9-character identifier assigned by the UK Department for Work and Pensions (DWP) to individuals for taxes, national insurance, and benefits tracking.
This tool generates mock NINO numbers in full compliance with the DWP's official numbering system. The default format is AA 12 34 56 X, where prefix and suffix letters follow strict mathematical rules.
