While the linked to article, a US TV station news site, does call it a "draft notice", I suppose I should explain to the non-US people here that this is not technically correct. There has been no draft in the US since the end of the Vietnam War. For roughly 40 years now, the US has had an all volunteer army. What Selective Service is required to do is to contact US citizen males on their 18th birthday and advise them that for the next 10 years they need to let Selective Service know their new address every time they move because in theory, in a national emergency Congress could pass a law reinstating the military draft and Selective Service is required to maintain accurate records of those who might theoretically be subject to such a draft. Whether such a draft would ever be done again is a great question, given how Congress currently seems incapable of passing anything non-controversial, let alone something as controversial as reinstating the draft. A crackpot Congressman or two has tried to get the draft reinstated and it's never had enough support to even get a vote on the floor of the House of Representatives. Whatever this is, technically speaking it's not a "draft notice".
Not to digress, but for those who don't know, the draft was very controversial during the Vietnam War, with the rich and powerful were able to get their sons exceptions to the draft or get them plum assignments in the National Guard that wouldn't require them to actually go to Vietnam. Listen to Credence Clearwater Revival's "Fortunate Son", which was written about the practice. There was so much animosity about the unfairness of the draft and the compulsion to fight in a war that nobody but a small number of politicians seemed to want that the US switched to a voluntary system, but one of the deals cut to move to this system was that Selective Service had to know where to get young men should the draft ever get reinstated. And yes, female US citizens are not subject to this at all.
