The dog ate your license. Or it was stolen. Or it was burned in the fire that ate Gramma’s house. Just go to the MVD, and bring proper forms of identification so that they can verify it’s really you. If you want a new license number, provide a copy of a police report stating that it was stolen. Either way you’ll be charged a fee, which kinda sucks, but maybe you shouldn’t have lost it, ya know? What? It wasn’t your fault? Sure, sure. They’ll hand you a temporary license, and then mail you a real one later. Piece of cake.
