BrianL 0 Posted November 13, 2013 Hi everyone, I've received a letter from Selective Service System (SSS) saying that I was registered. In the letter there's my SSN, date of birth, and Selective Service number? I just wanna ask if any of you have received the same letter and what do i need to response? Will it hurt me if I don't response back? Thanks. Share this post Link to post Share on other sites
