There is a hold on my GW account so I can’t check out books or register for classes. What do I do?

To reinstate your accounts, you must go to the Circulation Desk, return all overdue items, and pay your entire balance. If you think you have already returned all items and paid all outstanding fees, please call the circulation desk at 202-994-6840 and ask for the supervisor on duty. See University Holds for more information.
