I think you are talking about the tracking number starting with 2020....... . It's basically the number assigned to our passport application by VFS global and can be tracked on the vfs global site under the tab, "Track your Application" The link to that is as below:

the other AWB number which is mentioned, will get activated after 24 hours, once they have dispatched our passport from IRCC office.
Hope this is clear!
You will get some emails and messages from VFS during this whole process. My application is at IRCC office since Monday (07/12/2020) and I haven't received any messages after that. So, I believe I will get messages once my passport is stamped and left IRCC.
