Pennsylvania License and ID Gender Marker Change This form is self-determined, meaning you decide your gender marker and there is no other requirement other than your signature. Gender designation options on Pennsylvania driver’s licenses and photo ID cards are “M” (male), “F” (female) or “X” (non-binary). Form must be completed in person at a PennDOT Driver License Center.
