All Virginia Department of Motor Vehicles customer service centers will be closed on Saturday to enable the Virginia Information Technologies Agency to move the state’s mainframe services to a new supplier’s location.

While the mainframe is down, customers will also not be able to conduct transactions on dmvNOW.com. Web service will be restored as soon as VITA completes the move.

The move is part of an overall change from one long-term supplier to multiple suppliers with shorter-term contracts, a DMV release stated.
