All male US citizens between the ages of 18 and 25 are already required by federal law to register with the Selective Service System (SSS), which maintains the database of draft-eligible Americans.

Congress approved the automatic registration mandate last year, prompting more than 40 anti-war, religious, feminist and civil liberties organizations to demand that lawmakers end SSS registration

Eligible men may soon be automatically registered for the Selective Service, rather than registering themselves, as reported by The Hill. Most men between 18 and 25 are already supposed to register their names.
