How does someone register with the Selective Service?
Men 18 through 25 years old can register by completing a form at the post office. Some high schools have a faculty or staff member who serves as a Selective Service Registrar. Most men turning 18 can also register by mail, if they receive a Selective Service form in the mail. Selective Service System offers a comprehensive web page http://www.sss.gov/ that provides further information on how to register online.
