Here's what you must do... go to this website Selective Service System: Welcome and register Selective Service.

If you are a man ages 18 through 25 and living in the U.S. then you must register with Selective Service. It’s the law. You can register at any U.S. Post Office and do not need a social security number. When you do obtain a social security number, let Selective Service know. Provide a copy of your new social security number card; being sure to include your complete name, date of birth, Selective Service registration number, and current mailing address; and mail to the Selective Service System, P.O. Box 94636, Palatine, IL 60094-4636.
