Information for Parents & Family

Students may begin receiving mail up to 14 days before the official first-year check-in date.


The following address and format should be used for undergraduate mail, where #### designates the student's UNI. As of Fall 2021, the student's UNI will act as a mailbox number. If the student is a junior or senior who was assigned a mailbox number in prior years, it is still valid; however, these students may also access their mail using their UNI in place of their mailbox number if they so choose.

Student’s Full Name
#### Columbia Student Mail
70 Morningside Drive
New York, NY 10027-7236


Web forms may vary in how an address can be submitted. Try to include the #### UNI using one of the lines typically provided: either Address 1, Address 2, or Apartment.

The word "box" should never be used in the address. Mail should never be sent to a student's residence hall address.


Packages should be addressed to a student's mailbox. The Student Mail Center holds packages for up to 14 business days and sends regular email notifications to students during this time. For more information on packages, please see the Package Return Policy. For tips on sending mail to students via the U.S. Postal Service, please see Mail Tips.
