Mail Categories

There are three categories of mail handled by the Campus Mail System:

Campus Mail

Interoffice communications and delivery of envelope-size items between offices. Campus mail does not require postage.

Each individual unit administrator is responsible for insuring that all material distributed for their unit through the Campus Mail Service is consistent with University policies.

Brown or buff envelopes only should be used for Campus Mail. The use of other envelopes for this purpose may cause mis-mailing and unnecessary application of postage. The use of tape to seal envelopes should be held to a minimum and used only for those containing confidential information.

For campus mail, the name of the addressee and the department to which assigned is sufficient for on-campus delivery. Room numbers, building designations, numerical codes and abbreviations should not be used.

 Courier Mail Service

Free mail service is available to many of the State offices throughout Delaware. When addressing the mail piece you must include a state location code as part of the address. A list of the State offices and their codes may be obtained from the State of Delaware website or by calling Campus Mail at extension 2158. This service is not available to private or parochial schools.

 U.S. Mail

Off-campus mail for distribution through the U.S. Postal System. U.S. Mail requires the payment of postage and falls into the following classifications:
