Almost all U.S. citizens, aged 18 through 25, are required to register with Selective Service. Note that registering does not mean you will automatically be inducted into the U.S. military.
*At this time, the Selective Service System online registration site is temporarily unavailable for overseas registrants. For security reasons, overseas registrants should complete the Selective Service Registration form (PDF 48 KB) and mail it to the Selective Service System at the following address:
Selective Service System
Registration Information Office
P.O. Box 94739
Palatine, IL 60094-4739
U.S. Embassies and consulates abroad assist the Selective Service System with its registration program abroad. If you need assistance, email us at: ACSsansal@state.gov to schedule an appointment.
