Mailbox Keys

Columbia University issues mailboxes and mailbox keys to undergraduate residents of Columbia Housing only. Incoming residents receive their mailbox keys from Columbia Housing upon check-in.

Mail is not distributed to students without keys. A student who loses his or her mailbox key can request at the Mail window on the 3rd floor ramp of Lerner Hall. A valid University ID card must be presented and a non-refundable $50 fee applies in order to receive a replacement key.
