Many of our newer parents to tournaments have asked about signining up for a United States Chess Federation (USCF) ID #.   To do this, you would have to go to the US Chess Federation website ( and follow the links along the left hand side.  USCF ID#'s are a method for children to compare their "rating"  and strength versus other players.  Some tournaments require this, some do not.  However, we have been seeing much more of a demand to be certified to participate in local and national tournaments.
