Interoffice Mail

Mail Services picks up interoffice mail throughout the University for delivery to other departments and for relay to the appropriate mail centers. Small or large interoffice gold  envelopes are provided at no charge. To order small quantities of reusable interoffice envelopes, call Mail Services at 314-977-2246.

General Instructions

  • Place mail in an interoffice envelope, or fold and seal the flier with a label affixed.
  • Clearly indicate an addressee name, department name, building, and room number on the envelope. (Do not abbreviate.)
  • Leave in a visible location for the mail carrier to pick up.
  • Take to nearest drop-off location:
    • DuBourg Hall - Rm 262

Interoffice mail will be delivered to University departments at "Incoming Mail" drop areas according to designated schedule. Interoffice mail delivery service is not offered for off-campus locations. Mail to any other location — including the VA St. Louis Health Care System — needs to be sent via USPS.


Please keep all interoffice envelopes separate from mail that requires processing for the USPS. Pickup occurs two times per day at most locations and mail will be delivered the next day. Mail to be metered will be postmarked on the same day and picked up by the U.S.P.S. by 4:30 p.m.

Mass Mailings

Large Interoffice Mailing: Mailings that are too large for the mail carriers to handle cannot be picked-up without prior notice. To arrange for special handling, please call Mail Services at 314-977-2246.

Preparing an interoffice mailing to the entire University? Follow these instructions to facilitate timely delivery:

  • Separate mail before submittal to Mail Center
  • Separate by North Campus, South Campus or SSM Health Saint Louis University Hospital, building locations and departments
  • Contact Mail Services for pickup

Large Outgoing Mailing: 

  • Please have all mail facing the same direction with uniform envelope flaps ( all nested or all folded over). Do not tuck in flaps.
  • Separate international mail. It requires different processing.
  • Verify that all addresses are complete. Please check the database before printing the addresses.
  • Do not overstuff envelopes with an excessive number of inserts or improperly folded inserts.

Off-Campus Mass Mailing

The University maintains a Third-Class standard mail permit for use by departments to process mass mailings at a reduced rate. This service is available to all departments on the north and south campuses.

Standard Mail Permit 134 is issued to Saint Louis University, 221 North Grand Boulevard, St. Louis, MO 63103-2097 as a non-profit organization, and as such is the entity authorized to use this permit. The permit cannot be loaned to any profit-making organization nor used in conjunction with advertisements for products or services not directly related to the University's mission.

Bulk Mailings Prepared Outside the University:  Commercial printers/mailing businesses will prepare your standard mailing materials, sort the printed material according to zip code and current standard mail requirements, complete the PS FORM 3602N, and submit the mailing to the Weigher's Office at the main U.S. Post Office. Please provide the printer/mailer with the department's six-digit Banner fund number for tracking and accounting purposes, and have them send a copy of Form 3602N to Mail Services.

The person responsible for coordinating the department's standard mailing needs to ensure that the appropriate indicia is included in the layout of the publication being created.

A copy of the PS FORM 3602N must be submitted to Mail Services. For additional information regarding services, please contact Mail Services at 314-977-2246.


The Mail Services department coordinates the University's daily mail delivery from the USPS branch stations to University departments and meters all USPS mail submitted by departments. Mail Services staff concentrate on the delivery and pick-up of University business-related mail. Personal mail and third-class "junk mail" is not a priority.

The USPS mail for students is delivered to the Busch Student Center.

Departmental Incoming Mail

Mail is delivered to the designated "Incoming Mail" drops within each building.

Departmental Outgoing Mail

Mail prepared by departments to be metered through the Mail Center as first-class mail will be picked up daily from the "Outgoing Mail" drops in each building. Stamped mail may also be deposited directly into any USPS outgoing mailbox and should be kept separate from mail to be metered. 

The six-digit Banner fund number must be designated on individual mail pieces, or if there is a bundle of mail from a department, the bundle should be noted as all using the same fund number.

Official Business Only

First-class postage will be affixed to unstamped University mail via postage meter imprint in accordance with weight and destination rates. Postage will be applied only to mail identified as University correspondence; personal mail will not be metered.

Monthly Billing Charges

Postage costs will be billed monthly to the department shown on the return address or as otherwise indicated with the Banner fund number.

Submittal of Large Mailings

For mailings of more than 1,500 pieces, please inform Mail Services three to five days in advance of the actual mailing to ensure that there is sufficient postage on the University's Post Office account.

International Mail

Domestic and international mail must be separated by departments. If it is not separated in advance, the domestic rate may be applied incorrectly to international mail and cause delays in delivery and additional postage. Air or surface service should be indicated for international mail.

Special Mail Services

Departments requiring special mail services, such as certified or express mail, should call 314-977-2246 for assistance. Packages are shipped only via USPS or FedEx. We use UPS only for returns with a pre-printed return label and we cannot always accommodate expedited delivery.
