How to get your Number? A simple guide.
The World Tennis Number (WTN) is a global tennis rating system developed by the ITF that measures a player’s current level on a scale from 40 (closer to beginner) to 1 (elite). It applies to players of all ages, genders and abilities, from recreational players to professionals.
Whether you play socially, competitively or are returning to tennis after a break, your WTN helps you:
• Find better-matched opponents for more enjoyable and competitive tennis
• Compare your level globally, not just locally
• Track your improvement over time as you play more matches
• Enter the right competitions based on your current ability
• Connect with players at a similar level in your area
Getting your WTN is simple, quick and free in most countries.
How the WTN Works
Your WTN is calculated using match results and performance data. As you play more tennis, your rating becomes increasingly accurate.
Key things to know:
• Everyone starts with a WTN based on available data or a Rate My Game questionnaire
• Winning against higher-rated players improves your WTN more
• Recent matches have more influence than older results
• Separate ratings exist for singles and doubles
The more you play, the better your WTN reflects your true playing level.
How to claim your WTN
Step 1: Search for your WTN
Many players already have a WTN. Search by name using your national tennis association platform or using our player search feature to see if your WTN already exists.
Step 2: Register
If you don’t yet have a profile, you’ll need to register through your national tennis association or, if available in your nation, via our 'sign up' button.
Registration typically includes:
• Creating a free online account
• Linking your tennis activity (competitions, leagues or club play)
• Accepting basic terms and conditions
Step 3: Activate Your WTN
In some countries, you may need to activate your WTN by completing our Rate My Game questionnaire about your playing experience.
This helps ensure your initial rating is as accurate as possible.
Step 4: Play Matches and Improve Your Rating
Once active, your WTN updates automatically as you play more matches in:
• Tournaments
• Leagues
• Club competitions
• Approved match formats
Your WTN will adjust as your performance changes — making it a powerful tool for long-term player development.
