Application Status-East Carolina University

I applied as a transfer student to ECU yesterday. When I was applying, there was a part that said ECU ID# and that space was blank. When I logged on today, there are a series of number under it that starts with a “B”. I have tried to google and see if I could find what it means but I can’t. I was wondering if anyone knew what it meant.
Thanks in advance

Did you ever find out?

That’s your banner I’d number
