Departmental Mail

Departmental Mail is all USPS mail addressed to and being sent off-campus from the university’s unique zip code of 70803. The inbound departmental mail is collected from the US Post Office, sorted and delivered across campus to the various departments daily. Mail is sorted according to the LSU department name.

Note: Postage meter imprints paid for with LSU Funds are to be used for official business purposes only. Personal use of such postage is a misappropriation of state funds.

All departmental and campus mail is sorted and delivered by LSU department name. It is essential that a full department name be part of the address. Improperly addressed envelopes cannot be delivered in a timely manner, require additional handling, and may be returned to the sender. We discourage the use of acronyms and initials for the department name in the mailing address.

Purchase & Use
The university has established LSU Mailing Services as the mail dispatcher for the University (PS-91). LSU Mailing Services is responsible for compliance with appropriate US Postal Service rules and regulations.  All outbound mail must be identified and metered through LSU Mailing Services.

  • Mailing needs should be met through LSU Mailing Services/The UPS Store.
  • Departments must obtain prior approval from LSU Mailing Services for an exception to purchase and use postage stamps.  This exception would be granted only for occasional special or urgent mailing needs.  If prior approval to purchase postage stamps is granted, the department is expected to purchase them from the mail vendor on the main campus, The UPS Store, not directly from the US Postal Service.
  • The only exception is a situation where the mail vendor, The UPS Store, is unable to meet the department’s need, and will require written justification and prior approval from LSU Mailing Services.  
  • Requests may be emailed to That written email approval must be attached to all stamp purchase backup documentation.

Procedures for Control of Stamps

  • Postage stamps in a department’s possession must be treated as cash and held in a secure location. It is the responsibility of the department to maintain appropriate controls and auditable records supporting the use of the postage stamps, including to whom postage stamps were issued, the quantity issued, and the balance of postage stamps on hand.
  • Postage stamps purchased by a department may only be used for University business and may not, under any circumstances, be sold to employees, students or others, nor may they be used for personal purposes.
  • A department may only purchase postage directly from the US Postal Service in a situation where LSU Mailing Services/The UPS Store is substantially unable to meet their needs, and only with the advance approval of LSU Mailing Services. Postage stamps purchased directly from the US Postal Service are subject to the same conditions as postage stamps purchased from LSU Mailing Services/The UPS Store, as described above.

Note: Postage stamps and postage meter imprints paid for with LSU Funds are to be used for official business purposes only. Personal use of such postage is a misappropriation of state funds.

Bulk Mail Nonprofit Permit

On behalf of LSU Mailing Services, Auxiliary Services maintains a Nonprofit Bulk Mail Permit. Utilization of the nonprofit bulk mail permit for your department’s domestic mailings may substantially reduce the cost of postage. A minimum of 200 pieces, of identical size and weight, is required to qualify for nonprofit bulk mail. The use of LSU’s bulk mail permit must be authorized in advance by LSU Mailing Services. Authorization may be secured by submitting the Bulk Mail Control Number Request Form to: Approved nonprofit bulk mailings will be issued a unique LSU control number by LSU Mailing Services. Postage for the mailing will be drafted from an USPS advance payment account. Auxiliary Services will charge back the department for the postage used. If postage charges are not an allowable expenditure of University funds, Auxiliary Services will invoice the department for the postage charges.

When planning to use bulk mail, please consider and prepare for slower delivery times. Bulk mail is processed by the USPS on a lower priority basis than First-Class mail. There is no guaranteed delivery time. In state mail is typically delivered in about 3 to 6 business days, national mail is typically delivered between 7 days to 2 weeks. Bulk Mail is not forwarded if the addressee has moved, nor is it returned if undeliverable.

Bulk Mail Basics

  • Minimum of 200 pieces, of identical size and weight is required.
  • Postage rate is based on size, shape, and weight.
  • Mailing address list must contain only domestic addresses.
  • Mailing address list must be NCOA updated and CASS Certified.
  • Envelopes must be presorted.
  • Nonprofit bulk mail indicia must be printed onto each mail piece.
  • LSU control number may only be used one time, for one mail drop.

An LSU approved vendor should be engaged as a mailing agent to process the bulk mailing for your department, as there are specific USPS requirements that must be met when using the nonprofit bulk mail permit. Many print vendors will act as the mailing agent and preform bulk mail processes. The mailing address list used must be NCOA updated, CASS certified, and sorted into “presort” order prior to mailing. The mailing agent will complete certification and sorting, in addition to addressing the envelopes and completing the necessary PS Form 3602-N and depositing the bulk mailing at the US Post Office. Currently our permit is held at the Bluebonnet Station.

LSU Bulk Mail Control Number Request and Processing Procedures: The Department should complete the Bulk Mail Control Number Request Form and send to Mailing Services via email: A pdf of the print proof of the mail piece should be submitted with the control number request form. The control number request form must be submitted prior to the processing of the bulk mail job by the print vendor/mailing agent. Failure to do so could result in the depletion of permit account funds and/or your mailing to be delayed. We suggest submitting the control number request form no later than the day the final print proof is approved by your department. It is not required that the exact number of mail pieces and exact date be submitted on the request form, only an estimation is necessary.

Mailing Services will issue a LSU control number via email to the department contact within 3 business days of receipt of request. The department contact is responsible for providing the print vendor/mailing agent with the LSU control number.

The print vendor/mailing agent is responsible for the completion and submission of USPS Form 3602-N for Non-Profit Standard Mail when depositing the mail at the US Post Office where the permit is held.

The print vendor/mailing agent is required to, on the day of the mailing, notify LSU Mailing Services which LSU control number has been used along with the dollar amount of postage, the number of pieces mailed and the date deposited at the US Post Office. This information may be provided to LSU Mailing Services by the one of the three different methods.

Electronic Submittal of PS 3602-N allows the mailing agent to add additional user defined fields to the 3602-N form. For example, Customer Reference ID. The LSU control number may be entered in this field, and the data will be transferred into the USPS system and will appear on the final USPS Postage Summary which is then downloaded by LSU Mailing Services. This is the easiest, most efficient method.

Hard Copy Submittal of PS 3602-N does not allow for the LSU control number to appear on the final USPS Postage Summary. The LSU control number may be noted on the PS 3602-N form, however, extraneous information is not transferred into the USPS system. On the day the mailing is deposited at USPS, a copy of the completed 3602-N form with the estimated postage amount and associated LSU control number must be sent to LSU Mailing Services via email: An email containing the below specified information may be sent on the day of mailing to LSU Mailing Services,
LSU Control #
LSU Department:
Postage $:

If there is an Adjustment Summary issued for the submitted PS 3602-N form by USPS either at the time the mail is deposited or during processing the print vendor/mailing agent must promptly email a copy of the Adjusted Summary to LSU Mailing Services. If the contracted Vendor outsources mailing portion to another party, contracted Vendor must ensure the above procedures are adhered to by outsourced party.
