An abbreviation (usually M or F) denoting a person’s gender on legal documents and government-issued identification forms. Gender markers can be changed from one binary gender to the other (Wilson, 2014). However, some United States jurisdictions allow non-binary gender markers on IDs and driver’s licenses, represented by the letter “X.” Changing a gender marker on an individual’s driver’s license, ID, birth certificate, or passport may require different processes specific to state, county, or city regulations.
