I'm applying for aid- class of 2020- what does a 8-digit ID number mean?

I just have sent my application to Drexel for the early action decision November 1. I have filled the non custodial waiver of Drexel for financial consideration. However, in the form it says that I need to include 8-digit ID number. I don’t understand what that means because I haven’t received any 8-digit ID number. The deadline for css is November 15 and I haven’t received any reply for my question.

What should I do? Does anyone figure out what 8-digit ID number is?

Thank you

The 8 digit ID number is your Drexel ID it can be found on the Discover Drexel Portal.
