Pacheco Post Package Center

The Pacheco Post Package Center, located in yakʔitʸutʸu, provides secure mail and package distribution to all students living in the following residence halls: Sierra Madre, yakʔitʸutʸu, and Yosemite. Once received, mail and packages are processed and an email is sent to the recipient informing them of where and how to retrieve their package. Email notifications are sent to the recipients' Cal Poly email address, no exceptions.

For optimal service, we highly recommended that packages and sensitive mail be sent via a shipper using a tracking number and requiring a signature (i.e., UPS, FedEx, or USPS Express Mail).

It is recommended that any valuable items, such as computers and cameras, be insured for the value of the item. Neither Cal Poly Distribution Services nor the Housing Department will be responsible for the delivery of any packages that have a value over $50.

All packages received will use the unique bar code tracking number assigned to the package by the shipper to assure that the student receives the correct package. Each student is required to show his or her Cal Poly ID or some type of photo ID that matches the name on the package. A signature of the package recipient is also required after proper identification has been provided.
