Prior to entering, 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 without one you will be unable to sign-in.
Tournaments on the ITF Junior Circuit are graded according to the strength of entry, 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 World Ranking toget into the Main Draw of Group A, 1, 2, and 3 events, but even entry into Group 4 and 5 events is likely to be based on players' ITF rankings.
