The WCA¹ ID is a unique identifier given to people who have competed in an official WCA competition. Once you have competed at a competition for the first time, and the results have been uploaded (usually within a couple of days,) you will automatically have a WCA ID generated for you and it will be on the WCA website. When you sign up to the WCA website you’ll be given a profile and your ID is linked to your WCA profile. You may upload a picture to the profile (this is optional.)
