Prior to entering ITF events, all players must register for an International Player Identification Number (IPIN) membership. This alpha numeric identification number is a prerequisite to entering an ITF junior event anywhere in the world.
Since the ITF is closed on the weekends and it usually takes 1-3 days to get an IPIN, it is recommended not to wait until the last minute to get an IPIN. All players, including onsite alternates need an IPIN so if you show up the the tournament site without an IPIN you will be unable to sign-in.
Tournaments on the ITF Junior Circuit are graded according to the strength of player entries, with the most ranking points being awarded for the eight major championships (Group A), which include the four Grand Slam events.
Players will need an ITF Junior Ranking to get into the Main Draw of ITF events. Players will also usually need an ITF Ranking to get into the qualifying of Grade A, 1, and 2 events. Players without an ITF ranking are more likely to obtain entry into the qualifying of Grade 3, 4 and 5 events.
