What is College Board Id?

When filling out the SAT score section, there is a field for College Board Id (optional).
Any idea what is this and where to find it?

The only relating thing I can find is College Board Code, but this is for specific colleges for score reporting and does not seem relevant to this.

Somehow this got posted to the wrong, forum. Meant to post this to csu general forum.

You go to your SAT score report and you download it. Once you download your score report the CBID should be at the top right corner of the first page!
