Registry entry

United States Selective Service Registration

Register an eligible individual with the U.S. Selective Service System, as required by law of most people assigned male at birth between the ages of 18 and 25 living in the United States. This document describes the eligibility window and the small fixed set of registrant inputs. It does not submit the registration; the live sss.gov source is always authoritative (see verification).
