According to a statement from the United States (US) State Department, the first American passport with an “X” gender marking was issued on Wednesday, aiming to allow non-binary, intersex, and gender-nonconforming people to mark themselves other than male or female on their travel document, Reuters has reported.

US Secretary of State Antony Blinken announced in June that the X marker would be offered as an option on passports, following other countries, including Canada, Germany, Australia and India, which already offer a third gender on documents.

US Department Spokesperson Ned Price said in a statement that the US was moving toward adding the “X” gender marker as an option for those applying for US passports or Consular Reports of Birth Abroad.
