If you receive a key with an orange or grey tag attached in your mailbox with your name on it, it means that you have received a locker-size package. It has been put into a locker in the post office hallway in the Eisenhower Campus Center and you may retrieve it 24 hours a day with that key.
If you receive a green slip in your mailbox, it means that you have a package to pickup at the campus post office. If you get a green slip, it means the package is too large for a locker. You need to bring the green slip, along with your student ID to the service window for pickup during regular business hours.
If you receive a large, heavy package or item such as a computer, refrigerator, etc. you will receive a slip notifying you that you have an item to pick up at Central Receiving. Central Receiving is located in the Lenhart building, which is just across the railroad tracks, behind the Grantham Post Office.
