Question to the Department for Work and Pensions:
To ask Her Majesty's Government how many National Insurance numbers were valid on the latest date for which this figure is available.
As of 11:50am on 16th July 2021, the Department Customer Information System (CIS) holds National Insurance Number records for 72, 096, 863 Adults; where a Date of Death is not held on their record. As processes are in place to remediate invalid National Insurance Number records, the volume of Live Adult records are deemed to be valid.
