I just found out that my state allows anyone to self-declare and update their gender marker on their Driver's License without proof of GCS. All I have to do in my state is get a replacement license or ID card from the Department of Motor Vehicles (DMV), and then select the appropriate gender marker on the application form: male, female, or non-binary.
Unfortunately, I still have to use my birth name, which cannot be changed without a court order. My birth first name is sometimes given to females, so that is OK, but I'm not so lucky with my middle name. The good news is if I show up in person to make the change, I can have a new photo taken that also represents the new female gender marker on my ID.
I am very excited to take this step and finally have an ID that more closely resembles my authentic self. My appointment with the DMV is on Nov. 6th.
The states below let people change their genders on their licenses without proof of transition. Individuals can simply work with their state's Department of Motor Vehicles to update their information.
