Your library ID number is the 14-digit barcode number from your Blue Demon (ID) card. You can find it in the Transact eAccounts app on your mobile device. Open the menu under your photo, and click “More Information.” You will see an option to "Show Barcode".
The number is also located on the back of your physical Blue Demon (ID) card above the barcode.
Lastly, you can figure out your library borrower ID number by following a formula. Your library borrower number is
20511 + 7-digit DePaul ID number + 00.
For example, if your DePaul ID number is 7654321, your library borrower ID would be 20511765432100.
