Lost and Found

Security’s Lost and Found is the central lost and found location for the entire campus. We tag all items and enter them into our database. These items are stored in a secure location for 30 days. If your name, student number, or telephone number is anywhere on the item, we will do our best to get in touch with you by phone or email.

If we do not have your item when you first check with us, please wait a few days and check back with us again. Items often come to our office through the university’s inter-department mail which takes time to be sorted and delivered.


LOST AND FOUND will be closed during reading week February 20-24th 2023

 Our new office for item pickup is located in the Residence Commons Basement, room B104 until further notice.

New hours beginning in 2023 will be as follows:

Tuesdays      9 am – 1 pm

Thursdays     9 am – 1 pm

Friday            10 am – 12 pm

Please Note:

If you have found something please turn it over to Security as promptly as possible. Please do not attempt to contact the owner yourself. This often results in confusion for all parties involved. We have the resources to contact students and staff but if you believe you may know who it belongs to that information would be greatly appreciated.
