The International Tennis Federation (ITF) is the governing body of world tennis, made up of 210 national tennis associations or corresponding organizations of independent countries or territories. 
It was established as the International Lawn Tennis Federation (ILTF) by 12 national associations meeting at a conference in Paris, France on 1 March 1913, and discussions on rules and policy continued through 1923. It was at this time that two compromises were reached: the title 'world championships' would be abolished and wording would be 'for ever in the English language'. In 1924 it became the officially recognised organisation with authority to control lawn tennis throughout the world, with official 'ILTF Rules of Tennis'. In 1977 it dropped the word 'lawn' from its title, recognising that most tennis was no longer played on grass.
Originally based in Paris, its funds were moved to London, England during World War II; from that time onward the ITF has been run from London. Until 1987, the ITF was based at Wimbledon, it then moved to Barons Court, near Queens Club, and then moved again in 1998 to the Bank of England Sports Ground, Roehampton.
The ITF operates the three major national team competitions in the sport, the Davis Cup for men, the Fed Cup for women and the Hopman Cup, mixed teams. The ITF sanctions the four grand slams: the Australian Open, the French Open, Wimbledon, and the US Open.
While the ATP Tour and WTA Tour control most other high-level professional tournaments, the ITF runs developmental professional tours for men and women. The ITF Men's Circuit consists of Futures tournaments with prize funds of USD 10,000 or USD 15,000. Medium level men's tournaments are run by the ATP through the ATP Challenger Tour. The ITF previously also ran four-week satellite tournaments of roughly the same quality level as Futures tournaments, but they were discontinued after the 2006 season. The ITF Women's Circuit incorporates both lower and mid-level tournaments, with prize funds ranging from USD 10,000 to USD 100,000. Virtually every ATP and WTA player started by playing on the ITF circuits.
The ITF is responsible for maintaining an international under-18 junior circuit for boys and girls, as well as a wheelchair tennis circuit.
The International Tennis Number (ITN)  is an international tennis rating system that gives tennis players a number that represents their general level of play. Players are rated from ITN 1 (ATP or WTA standard or equivalent) to 10 (starter players).
Conversion charts have been developed linking the ITN to other existing rating systems in ITF tennis nations and in time it is hoped that every tennis player worldwide will have a rating.
Below ITN 10 there are 3 further categories linked to the slower balls:
• 10.1 for players using green balls on the full-size court
• 10.2 for players using orange balls on the 18 metre court
• 10.3 for players using red balls on the 11 metre court
Once players can ‘serve, rally and score’ they should have a rating to help them find players of a similar level to play with.
In late 2004, the ITF initiated a new player registration process, IPIN (International Player Identification Number). This is online based and was implemented to handle the large number of players around the world. A player's IPIN, which is 3 letters followed by 7 numbers, is assigned upon registration and is required for all ITF events. A player's IPIN will not change during the course of his or her career. Once registered, players can use the website to access items such as tournament information such as their code of conduct. Fees vary depending on the ITF circuit chosen by the player.
In 2013, the ITF Board of Directors found that the Tunisian Tennis Federation had 'breached the ITF Constitution by interfering with international sporting practice and ordering Tunisian player Malek Jaziri not to compete against Israeli player Amir Weintraub at the 2013 Tashkent Challenger in October. "The Board ... voted to suspend Tunisia from the 2014 Davis Cup competition." ITF president Francesco Ricci Bitti said: 'There is no room for prejudice of any kind in sport or in society. The ITF Board decided to send a strong message to the Tunisian Tennis Federation that this kind of action will not be tolerated.'
