Mail Services


Students should use their UNI to receive and collect mail through Mail Services. If you are a junior or senior who was assigned a mailbox number in prior years, please use your UNI in place of your mailbox number.

Mailbox Policy

Students living in Columbia Housing are guaranteed a mailbox continually for the four years they are guaranteed housing, while they remain in the residence halls. This applies to all new students, including first year and transfer students. Students who move off campus, take a leave of absence other than study abroad, withdraw from classes, or for some other reason lose their guaranteed housing status will no longer maintain a Columbia-issued student mailbox.

Collecting Packages

The U.S. Postal Service and other package delivery services deliver mail to Columbia Mail for distribution. Incoming mail and packages for residential CC/SEAS students are received at the Student Mail Center in the lower level of Wien Hall. It is the primary pick-up location for undergraduate residents of Columbia Housing. Upon receipt of mail or a package, the Student Mail Center will send the student an email notification indicating the pick-up location.

Accessible Package Locker

Students with disabilities or temporary injuries can request access to the accessible package locker in John Jay by contacting Disability Services.

For instructions on how to address your mail, please see the Receiving Mail and Packages guidelines on the Columbia Mail Services website.
