National Insurance Database
Dawn Primarolo (Paymaster General, HM Treasury; Bristol South, Labour)
The total number of National Insurance (NI) accounts on the National Insurance Recording system (NIRS2) is 73 million. Each year we process one billion transactions and changes to NI records.
We have no information on the proportion of the entries as being false.
HMRC has a number of well established processes in place to validate and review the accuracy of National Insurance records. Where incorrect use of a National Insurance Number, such as fraud, is identified, corrective action is taken.
