HC Deb 13 November 2001 vol 374 cc699-700W
Mr. Clappison

To ask the Secretary of State for Work and Pensions how many surplus national insurance numbers have been removed from his Department's Central Index since 1997; and what plans he has to tackle the problem of bogus and surplus numbers. [7477]

Malcolm Wicks

The Departmental Central Index (DCI) Data Cleaning Project removed 100,000 surplus duplicate National Insurance numbers (NINOs) from the DCI between April 1997 and March 2001.

To prevent the creation of further bogus and duplicate NINOs, the Enhanced NINO allocation process was introduced nationally from April 2001.
