The MOT test number contained on the certificate gives access to the vehicle's current test status as well as its test history from 2005 onwards, via the DVSA web site. MOT certificates in Northern Ireland continue to be issued on paper, accompanied by a paper 'certificate disc' which must be displayed on the vehicle. Display of these discs has been mandatory on Northern Ireland tested cars since 2008. However, this was abolished in April 2015.
