U.S. federal law requires all men to register with the Selective Service System within 30 days of their 18th birthday. 

Not only is registration important for protecting access to federal benefits, it is essential to our nation's security in the event of a national crisis. 

Note that registration with the Selective Service does not mean enlisting in the armed forces.

Registration is quick and easy to do with the options below:

1.      Online registration: https://www.sss.gov/register

3.      In-person at any U.S. Post Office
