The first ever non-binary US passport has an “X” in the gender box, signalling that the holder does not identify as either male or female.
It was issued to Dana Zzyym, a 66-year-old intersex activist, who sued the State Department over the issue in 2015.
The US Navy veteran said it was “an exciting moment for me” after getting the new passport.
Zzyym, who identifies as non-binary, was previously denied a passport after failing to mark male or female in an application.
More than 10 countries, including Canada, Germany, Australia and India, already offer a third gender on documents.
