MAIL DELIVERY/PICKUP SERVICES Intramural Mail is a service provided to University faculty and staff for the transmission of messages relating to the business of the University. It is not to be used for personal communications or by organizations involved in any solicitation or business offerings that are not part of the University. Most intramural mail is delivered the day after it is picked up by Penn Mail Service. To ensure that intramural mail is handled as expeditiously as possible, please follow these instructions:
- Use gray intramural envelopes for all intramural mailings. Used envelopes are available at no charge from Penn Mail Service.
- Use the correct mailing codes. If the building does not have a mailing code listed in the directories of this website, it does not receive intramural mail. Mail codes are also listed on the back of the large gray intramural envelopes.
- Proper addressing should include the following: Name of addressee; Department name/Office number; Building name/Mailing code.
LARGE VOLUME MAILING Any department planning a large volume intramural mailing must contact Penn Mail Service at least one week prior to its desired delivery date. All mailings must be in building code order. For specifics, contact Penn Mail Service. Also for large mailings, whether first class or intramural, we ask that all Departments use the mail tubs provided by Mail Service. Cardboard boxes are usually not suitable for heavy mailings, as they tend to break in transit. Please notify Mail Service at least 2 or 3 days prior to your mailing and we will supply you with empty tubs for collecting your mail.
