Internal (Campus) Mail

This mail consists of correspondence for delivery to internal University addresses. To provide proper delivery, internal mail requires a name, department and mail code.

Mail Codes

We use mail codes to identify a location internally. Each department has been assigned a mail code. Click here for an on-line view.


Inter-Office (Campus Mail) Envelopes

These are envelopes used repeatedly for in-house or internal mailings. When using inter-office envelopes, make sure the previous marking has been marked out to ensure proper handling and direction to the intended recipient. The addressee is always to appear on the last line. Do not address between previous markings. Place labels over the last used line or label to extend the usefulness of the envelope and don't skip lines. Single piece, (non-confidential post card style) correspondence need not be inserted into inter-office envelopes. Simply address it to the proper person, department, and mail code (not room number).

Plain Envelopes

When addressing internal mail in white envelopes, please have CAMPUS MAIL printed in the upper right corner since such mail can be mistaken for U.S. Mail. This will enable us to identify the envelope as campus mail.

Single piece non-confidential correspondence need not be inserted into inter-office envelopes. Simply address it to the proper person, department, and mail code.

Internal Parcels

The addressing of parcels and packages for internal distribution is the same. Use full name, department, and mail code. Contact us when you have large parcels to be picked up. 359-7993

Change of Address

A change of your internal location must be acted upon promptly if you or your department are moving. As soon as you learn of your new location, send an email to or memo to Mail Services 125 TAW. Indicate the new and old location and the telephone number. You must notify correspondents, magazines, etc., of your new address and request your department to forward mail to your new address.


Appropriate Size and Strength

(a) The size should properly accommodate the insert(s). Excessively large envelopes will not keep the inserts firm. The inserts in such envelopes slide about, create an imbalance of the envelope, risking ripping and loss of contents. A snug fit keeps the enclosure firm in the envelope providing for effective mail handling.
(b) Conversely, when an envelope is overstuffed it can burst at the seams upon impact with other mail. The result can be a total loss of the mailing.
(c) The strength of the envelope should be such to withstand the weight of its contents. If there is stress at the seams or sharp edges, the envelope is overloaded and can burst or tear apart and possibly lose its contents.
