In the year from 1 April 2005 to 31 March 2006, fewer than 1 per cent. of those who attended a Jobcentre Plus Evidence of Identity interview were referred to the Immigration and Nationality Department as potential immigration offenders.
Adults who require a NINO are asked to bring a number of documents to the Evidence of Identity interview to help prove their identity. These documents are set out in form ISSPA5JP, which is available from Jobcentre Plus and social security offices. Copies have been placed in the Library. It is also available at www.dwp.gov.uk
