What’s XNUM?
XNUM is a free unique number created specifically to make sure your acceptances are credited to you and only you.
Why XNUM?
You shot the picture. You entered the exhibition and your picture was accepted.
How do you make sure the acceptance is credited to YOU and not someone else with the same name? And what if you change your name or move country?
The answer is simple - by having a unique exhibitor number which you use in all the exhibitions you enter. Your acceptances are then credited to your personal number and no one else.
