The submission code is a 13-digit number to help us identify your work. You can find your codes under “My submissions”. Each physical sample of your submission should be discreetly marked with this code, either written by hand or on a small printed label.
The code is 13 or 14 digits in the format CCCC-ΧXX-SSSSSS (e.g. 0234-011-220011).
To see your submission code, all you need to do is click on your “Checkout Submissions” button. There, each code is noted in red, on the right of your submission title.
