Welcome to Columbia Mail

Undergraduate Mail FAQ

The USPS website says that my package has been delivered, but I haven’t received it yet. Where is it?

A confirmation from the USPS only confirms a package’s delivery to the post office of the applicable zip code (i.e. the Manhattanville branch post office, for 10027); it does not confirm delivery to the Undergraduate Package Center. From the date of confirmed delivery to the post office, anticipate an additional 1-3 business days. The Undergraduate Package Center sends email notification to students within 24 hours of receipt. 

USPS informed me that my package was rejected by the Undergraduate Package Center—why is this?

The Undergraduate Package Center never rejects deliveries made to students with mailbox assignments. A “rejected,” “attempted delivery" or "notice left” status usually occurs when the USPS attempts delivery to the Package Center after business hours or over the weekend. The USPS will reattempt delivery the following business day. The Undergraduate Package Center sends email notification to students within 24 hours of package delivery. 

Where do I pick up my package?

The Undergraduate Package Center on the 4th floor of Lerner Hall is the primary package pick-up location for undergraduate residents of Columbia Housing. During Fall Check-In, auxiliary package pick-up locations are noted in the “Location and Hours” section of the home page.

Look for the applicable package pick-up location indicated in the email notification sent by the Undergraduate Package Center. Please note that the Package Center is moving to Wien Hall this August. We will share more information on the website and via email in the coming weeks.

Does the Undergraduate Package Center sell stamps?

No, the Undergraduate Package Center is not a USPS vendor so does not sell stamps and cannot add postage to mail. However, if USPS parcels and packages already have postage, they can be shipped from the Package Center.  Note that the Package Center does process FedEx shipments; for more information on these services, click here.

Administrative Mail FAQ

How long does it take for interoffice mail to be delivered?

Allow up to two business days from the time of deposit for interoffice mail to be delivered to its destination. Note additional processing may be required by the receiving department before interoffice mail reaches its destination.

What is a mail code and how do I find it?

A mail code is a four-digit number assigned to each department and office on the Morningside Heights campus. The first two digits represent the building, while the last two digits represent the department or specific location where mail will be delivered.

To find the mail code of a department, academic building or individual, visit the online University directory and search by the name of the department or an associated staff or faculty member, or contact the Department Administrator. Only Morningside campus locations have mail codes.

Where is the Administrative Mail office located?

The Administrative Mail office is located in the Service Building, Room 101. Enter the Schermerhorn Building (see map) and take the elevator to 2nd floor. Follow the corridor to your right, all the way to the end. You can also enter via the Engineering Terrace parking entrance at 119th Street and Amsterdam (see map).

I lost the key to my department mailbox. What should I do?

Please contact Administrative Mail for a replacement key. A $75 replacement fee applies and is billed to the chart string of the applicable department.
