B. Uploading match and player data
1. Associations may only upload results data to the ITF World Tennis Number for tournaments that they own or which they are the official sanctioning authority. This helps to ensure that match results for the same tournament are not uploaded by multiple organisations and avoids creating duplicate matches in the system or potentially posting different scores for the same match. Only the recognised ‘owner’ of each event will be permitted to upload the official results.
2. All international events will be uploaded by the ITF only – including ITF Circuits, ATP Tour, WTA Tour, Grand Slams, Davis Cup, Fed Cup, and Olympics.
3. All tournament and player records must have a unique ID that distinguishes them within your entire database.
4. The primary way of uniquely identifying each a player across all association databases is by their globally unique Tennis ID (or IPIN). Results should, therefore, include a player’s Tennis IDs so that ITF World Tennis Number can easily and accurately identify them and prevent duplicate players being created in the system.
5. If a set of tournament results is uploaded which contains players who do not already exist in the ITF World Tennis Number database (i.e. they do not already have a Tennis ID), a new player record and Tennis ID will be created for each of them. Please check that any new players that you are uploading do not already exist in ITF World Tennis Number before submitting results so that duplicate player records and multiple player profiles (with different ITF World Tennis Numbers) are not created during the results upload process.
6. Do not upload results with large number of new players who do not already exist in the ITF World Tennis Number database. A maximum of 20 new players can be included in each set of tournament results uploaded to the database. If you need to add a larger number of new players to the ITF World Tennis Number system at one time, this must be done via the bulk player import process. Please contact the ITF World Tennis Number Help Desk for assistance with bulk player creation.
7. Results should only be uploaded for completed tournaments. Please do not upload results for events that are still in progress.
8. Always upload the complete set of results data for each tournament or event. Do not upload individual draws or results for single rounds. Each time you upload results for a tournament any existing data for that tournament in ITF World Tennis Number is deleted and replaced by the new set of data provided.
9. Results can be uploaded at any time but it is recommended that they are uploaded in a batch at the same time every week.
10. Do not re-upload results for a completed tournament which is already in ITF World Tennis Number unless it is to correct data errors.
11. Match and player data can only be submitted to ITF World Tennis Number by associations. This is to protect the integrity of the Numbers being produced. Please contact ITF World Tennis Number if you need to authorise a third party or results service provided to upload your data on your behalf.
