Here's the rest of it:
FOR FEMALE TO MALE (FTM) INDIVIDUALS
People who were assigned female at birth are not required to register with the Selective Service regardless of their current gender or transition status. When applying for federal financial aid, grants, and loans as a man, however, you may be asked to prove that you are exempt. To request a Status Information Letter (SIL) that shows you are exempt, you can either download an SIL request form from the Selective Service website (
http://www.sss.gov/PDFs/SilForm_Instructions.pdf) or call them at 1-888-655-1825. This service is free and the exemption letter you will receive does not specify why you are exempt so it will not force you to out yourself in any other application process. The Selective Service does, however, require a copy of your birth certificate showing your birth-assigned sex. If the sex on your birth certificate has been changed, attach any documentation you have to that affect. Once you receive your Status Information Letter, keep it in your files. For those FTM people who transition before their eighteenth birthdays and change their birth certificates, it is also possible to register with the service. However, no one may register after their twenty-sixth birthday. Also, please note that although Selective Service materials refer to transgender people as "people who have had a sex change," their policies apply to those who have transitioned regardless of surgical history.
FOR MALE TO FEMALE (MTF) INDIVIDUALS
People who were assigned male at birth are required to register with the Selective Service within thirty days of their eighteenth birthday. This includes those who may have transitioned before or since then. The Selective Service uses Social Security and other databases to determine who they believe was assigned male at birth. As of now, it is unclear whether transgender people are eligible for military service, but you are required to register nonetheless, and this is necessary to gain access to certain government benefits.
NAME CHANGES AND THE SELECTIVE SERVICE
People who are assigned male at birth and who are required to register are also required to inform the Selective Service of any legal name change or change in other record information such as address up until your twenty-sixth birthday. This does not include change of gender as the Selective Service policy is entirely based on birth-assigned sex. For transwomen and others who were assigned male at birth and have registered with the Selective Service, notification of a name change is legally required within ten days.
To update your records, fill out the Change Of Information Form attached to the Registration Acknowledgement Card with your new name. Alternatively, you can fill out a Change of Information Form called SSS Form 2, which you can obtain at any United States Post Office or U.S. Embassy or Consulate abroad. You may also change your information with the Selective Service by letter. In the letter, include your full name, Social Security Number, Selective Service Number, date of birth, current mailing address and new name. With any of these three methods, you must attach official documentation of your name change and mail it to the Selective Service. Updates take four to six weeks, after which you will be mailed a new acknowledgement card.
