ITF World Tennis NumbeR

The ITF World Tennis Number is a rating system for all tennis players across the world. It makes it easier for everyone who plays tennis in Britain to organise and play against opponents of a similar standard.

Whether you’re playing at Wimbledon (we can dream), or just meeting a friend to play matches at your local court (much more likely), everyone’s welcome – and everyone can have their own Number.   

  • A world-wide rating system that ranges from 40 (recreational players) to 1 (pro players).  
  • Has separate ratings for Singles and Doubles players – a world first
  • Uses a sophisticated algorithm to calculate your rating and updates it every time you compete
  • Counts sets and matches played, which means the more you compete, the more accurate your WTN will be
  • Has a personalised ‘Game zONe’ feature to help you identify opponents with a similar WTN


WTN is free for everyone

If you’re an LTA Advantage member in the Play, Play+ or Compete categories you’ll be able to get your own ITF World Tennis Number. As a Local Tennis Leagues player, you are entitled to the Play+ tier for free.

Having an ITF World Tennis Number is required for acceptance into certain competitions (this’ll be made clear when you enter) and is a requirement to join Local Tennis Leagues.
