What's your number?
Developed by the International Tennis Federation (ITF), the world governing body of tennis, the ITF World Tennis Number (WTN) is one of the most advanced and accurate rating systems in the world. It’s free to use for all ages and genders and is being adopted by the USTA and in over 135 countries.
WTN is a 40-1 global rating scale. For now, players with recorded matchplay in the USTA and ITF database will be given a number – one for singles and one for doubles - and will be updated weekly using millions of matches worldwide. Beginners start at 40 and professional tennis players will be closer to 1. In the coming weeks, you will be able to view your ITF World Tennis number on your usta.com profile.
The USTA has announced that players will be able to view their WTNs on their Player Profile beginning June 8. The launch of WTN for widespread use in tournaments is scheduled for June 21. Additional tools for viewing match results, searching, and comparisons will be available on the ITF’s website on or shortly after June 21.
Over the coming weeks, we will be sharing information and hosting webinars to help you learn about the ITF World Tennis Number, prepare for its release, and to show you all the exciting features in the works that will help elevate your game.
In the meantime, below are a number of resources to get you up to speed on the new rating system and how it will be used in USTA Northern California.
