Mail Routing

Mail Sent to a P. O. Box Vs. Mail sent to a Street Address:

Sending mail to a P. O. Box will get your letters there quicker.  A Yale street or building addresses are not associated with mailboxes, your piece (if addressed to a building or street) of mail will get rerouted to one of the central mail offices and may take one week or more to reach your office (via campus mail.)
