All US males over the age of 18 are required by law to register with the Selective Service. The Selective Service Registration System allows public users to enter a male’s last name, social security number and date of birth to see if he is registered with the Selective Service. This is a great way to verify that an 18+ year old US male’s last name, social security number and date of birth match up with Selective Service’s public records.
