Information for Parents & Family


The following address and format should be used for undergraduate mail. As of Fall 2021, the student's UNI will act as a mailbox number. If you are a junior or senior who was assigned a mailbox number in prior years, please use the below format, using your UNI in place of your mailbox number.

Student’s Full Name
70 Morningside Drive
[Full UNI]
New York, NY 10027-7236

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

The word "box" should never be used in the address. Mail should never be sent to a student's residence hall address. The Student Mail Center is located in the lower level of Wien Hall.


Packages should be addressed to a student's UNI. 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.

Tips for Shipping 

Every shipped box should have your full name and address clearly labeled and securely affixed to at least two sides on the outside of the box. Put your name and address on the inside of the box as well. If your shipment consists of more than one box, number them “1 of 4,” “2 of 4,” “3 of 4,” etc. Please use the correct address format for your labels. 

When possible, pack electronic equipment and other fragile items in the manufacturer’s original container and padding. If this is not possible, make certain to pack each item separately and protect all sides with at least two inches of protective padding.
