IPIN Tennis: What It Is, What Changed, and World Tennis ID
Last reviewed against official sources on 22 August 2026.
The short version
IPIN — the International Player Identification Number — is now the World Tennis ID. The portal you used to log into, the IPIN system, is now World Tennis Tour Zone, reached at tourzone.world.tennis. Your existing number and your existing email and password carry over — there is no new account to create.
What was IPIN?
IPIN stood for International Player Identification Number. It was the single ID that followed a player through every tournament sanctioned by the International Tennis Federation — junior, pro, wheelchair, beach and Masters alike. Your IPIN membership was both an identity and an account: it was how you searched the tournament calendar, submitted entries, withdrew before a deadline, checked whether you had made the acceptance list, and saw your ranking history. Without an active one, a result could not turn into ranking points.
Because it had been called that for two decades, the word is still everywhere — in club conversations, federation emails, tournament fact sheets, and in the 2026 Masters regulations themselves, which still carry a regulation headed “International Player Identification Number (IPIN)”. That is the main reason this page exists: the thing was renamed, but the vocabulary has not caught up.
What is the World Tennis ID now?
The World Tennis ID is the same identifier under a new name. When you register for World Tennis Tour Zone membership you receive a unique World Tennis ID for the tour or tours you compete on, and it stays with you for the rest of your playing career. Players who already had an IPIN did not receive a new number: existing IPIN numbers were transferred to become World Tennis IDs.
What is World Tennis Tour Zone?
Tour Zone is the membership service and player portal — the system formerly known as IPIN. It is where the administrative side of competing lives:
- the tour calendar and tournament information
- tournament entries, withdrawals and acceptance lists
- player resources and notifications
- your ranking and World Tennis Number history
It is available around the clock, in English, French and Spanish.
Did existing IPIN users need a new number or account?
No. According to the official Tour Zone guidance, existing IPIN numbers and login details — the same email address and password — were transferred across to the World Tennis ID. If you are being asked to create a fresh account, check the address in your browser bar first: you are probably on an outdated link or a lookalike page rather than the official portal.
Where is the official login now?
The portal moved from the old IPIN web address to tourzone.world.tennis. Old itftennis.com/ipin links still circulate widely — in federation PDFs, tournament fact sheets and years of forum posts — so it is worth updating any bookmark you rely on.
Who needs a Tour Zone membership?
Anyone entering a tournament sanctioned by World Tennis. That covers the World Tennis Tour at professional and junior level, the wheelchair and beach tours, and the World Tennis Masters Tour. If you only play club matches, local leagues or friendly tournaments, you do not need one — none of that runs through the official system, and no ranking points are involved.
Masters tennis and the World Tennis ID
For age-group players this is the gate to the whole calendar. The World Tennis Masters Tour runs in five-year divisions from 30+ to 90+, and the 2026 regulations are explicit that entries and withdrawals go through the official portal and that both the entry fee and the membership fee must be paid for a result to earn ranking points. Tournaments are graded MT100, MT200, MT400, MT700 and MT1000, with World Championships above them.
Before you enter anything, it helps to know which division you belong to — eligibility runs on your age at 31 December of the competition year, not on the day you play. The Masters age category calculator works it out for any year.
World Tennis ID vs World Tennis Number (WTN)
These are two different things that get confused constantly, largely because both are now branded “World Tennis”.
| World Tennis ID | World Tennis Number | |
|---|---|---|
| What it is | An identity — your player account number | A rating — how well you play |
| Formerly | IPIN | Introduced as the WTN; no earlier name |
| Scale | A unique number, no meaning attached | 1 to 40 — lower is stronger |
| Changes over time | Never — it is yours for your career | Weekly, from match results |
You need the ID to enter. The number is one of the things tournaments may look at when deciding who gets in.
Common mistakes and outdated links
- Registering twice. Your old IPIN carried over. Creating a second account splits your history and creates a mess that has to be merged by hand.
- Following an old bookmark. Anything pointing at the old IPIN address should be updated to the Tour Zone domain.
- Letting the membership lapse. An expired membership can block an entry and stop a result counting toward ranking points, even after the match is played.
- Confusing the ID with the WTN. See the table above — one gets you in, the other describes your level.
- Assuming “ITF” is gone. The trading name changed to World Tennis on 1 January 2026 and the brand went live in June 2026, but ITF remains the legal entity and still appears in regulations, historical results and many federation documents. Both names refer to the same body.
