                         Tips  -  WTID entry issues
 

Entry Problem:  The WTID site advises you are ineligible
when you try to enter any event.

Solution : Your WTID has to be renewed. Check your profile and
check your subscriptions to see when your WTID expires. You can
renew your WTID 2 months before this date. If the tournament you
are trying to enter is held after your expiry date you will have to
wait until 2 months before your expiry date then renew your WTID
and complete your online entry.

WTID Fee Issue:
This issue was partially resolved on Feb 12 2026.
In MT400 MT700 MT1000 tournaments the WTID
fee is paid via World pay when you initially enter on WTID.
In some cases if you then go back to enter an extra event
or change an event or enter a partner you are asked to
pay the USD$12 WTID service fee again. This only appears
sometimes if you are adding an extra doubles or mixed to
your existing entry.

Solution1: If you are adding a doubles try asking your partner
if they can add the pairing on WTID without being asked to pay
again.

Solution2: Email the World Tennis at masters@world.tennis 
with your worldpay receipt for the US$12 and indicate details
of the event you are trying to add. The World Tennis office will
add this extra entry manually to the WTID site.

Note - In MT200 tournaments and below the WTID Service fee is
collected as part of your entry fee payment. Check the fact sheet for
the entry fee payment site.

Doubles Problem : The WTID site advises your partner is
ineligible when you try to add them with their WTID.

Solution : Your partner has to renew their WTID by logging into
their own WTID and in their profile follow steps to renew WTID. 
Once this is done you can add them as partner with their WTID.

Doubles Problem :* Trying to add a partner with their WTID
and you are told they are already entered when they are not.

Solution 1: Ask your partner to enter the doubles and then in
partners click ADD and then click Select from pool and confirm.
Then you can login to WTID  enter  the doubles and add them
as your partner with their WTID.

Solution 2: You enter the doubles and then in partners click
ADD and then click Select from pool and confirm.
Then ask your partner to login enter the doubles and add
you as their partner using your WTID .
 

:* The above issue typically occurs when your partner has already entered
some events in the tournament and then you are adding another doubles.
