USPS & Interoffice Mail

Pickup is made at established collection points only. Carriers may not collect or deliver mail to an unauthorized area. Any variation must be authorized by Delivery Services. Requests for new collection and delivery points, or changes in existing points, should be requested in writing via email to the Manager of Delivery Services. The e-mail address is

Delivery and collection schedules are established by Delivery Services based on location, mail volume, vehicle patterns, and U.S. Postal Services (USPS) schedules. If you have an unusually large volume of mail or heavy packages to be picked up, please make special arrangements by calling Delivery Services. Requests made by 11:00 a.m. are on a same-day basis.

Incoming Accountable Mail

Accountable mail is all mail with an assigned tracking number. The categories of USPS accountable mail include: Certified, Registered, Express (overnight), Delivery Confirmation and Insured. All accountable items are received by Delivery Services and logged into the tracking system software. An email is generated by the software and sent to each recipient notifying the individual that a parcel was received for them. All accountable items are delivered to the centralized delivery areas of each college and/or division. These items are signed for by the administrative staff in each area. The items are then distributed by these areas to the recipient per the college and/or division’s internal procedures.

D. Preparing Mail for Pickup

The departments are responsible for preparing and sorting their outgoing mail for pickup according to the following instructions:

Outgoing USPS

"To Be Metered Mail"

  • All mail must have a complete University of Houston return address which includes the department name and 5 digit zip code plus the 4 digit mail code add-on.
  • Keep domestic and international mail in separate bundles.
  • Prepare the following in separate bundles: post cards, letter size envelopes, large envelopes (flats) and "accountable" mail.
  • Each bundle type must have a completed Department Mailing Card or DMC attached.
  • Letter size envelopes can be sealed by the meter machine if the flaps are extended (open).


  • Envelopes that are received with the flaps down and not sealed will be returned for "flapping" (the extending or opening of all envelope flaps) to the originator.
  • Envelopes that are bulky (or more than 1/4" thick) must be sealed by the department as the mailing machine will not seal them properly and/or they will not be able to be run through the mailing machine.
  • Never use staples to secure the opening of your mail piece, flaps or folded flyers.
  • Personal stamped mail should be kept separate from mail "to be metered."

Interoffice Mail

Interoffice mail should be bundled together and not mixed with any other type of mail. Address all interoffice mail using the proper complete mail code (see Campus Mail Codes). Building and room numbers are not necessary - only the person's name and mail code are needed. Be very specific and include sufficient information to assure proper delivery. Unclear or incomplete addressing can cause a delay in delivery. An example of a correctly addressed piece of interoffice mail:

"John Smith 2020"

Only interoffice envelopes should be used for interoffice mail; otherwise, the envelopes may go through the postage meter which would incur a cost for your department.

There is interoffice mail delivery to the Downtown, Clear Lake, Cinco Ranch, Sugar Land and North West campuses. Please consult the Department Mailing Code listing for proper mail codes to these areas. There is no interoffice mail to the UH Victoria campus. All UHV mail is processed through the USPS on a daily basis. Address all mail to UHV in the following manner:

University of Houston - Victoria
Attn: Department and/or name of recipient
3007 Ben Wilson
Victoria, Texas 77901-4450

E. Unique Zip and Add-ons

The University's unique ZIP is 77204.

Zip codes move the mail faster. The U.S. Postal Services' sorting equipment is able to read Zip codes and sort approximately 36,000 bar coded pieces of mail per hour. Mail without Zip codes must be held for conventional sorting at slower speeds. Please make sure that the mail is machine readable; it will speed the processing - refer to "Addressing For Success" for correct addressing procedures.

Use the above unique Zip code plus your department's numeric 4-digit mail code as part of your return address when corresponding. For example, if your numeric four digit mail code for interoffice mail is 1002, your 9 digit zip code for all off campus correspondence is 77204-1002. Notify your correspondents of the correct zip code whenever possible.

The additional four digits for departments improves delivery of campus mail. Incorrect delivery frequently occurs when incomplete names are used for departments and offices (for example, using Psychology for Educational Psychology, which is a department under Education, not Psychology; or Business for both Business Administration and Business Affairs, etc.). Clearly, identifying each department and its 4-digit ZIP add-on will help alleviate this confusion.

F. Addressing for Success - Domestic

Copy and Distribute!

  • Machine-print all address information.
  • Make sure print is clear and sharp.
  • Ensure address characters don't touch or overlap.
  • Black ink on a white background is best.
  • Maintain a uniform left margin. Do Not Center the lines of an address. 
  • Omit all punctuation.
  • Include floor, suite and apartment numbers whenever possible. (See Mailers Guide - Miscellaneous.) Put the city, state and ZIP Code or ZIP + 4 in that order on the last line. If there's not enough room, you can put the ZIP Code or ZIP + 4 alone on the bottom line.
  • Use standard two-letter state abbreviations. (See Mailers Guide - Miscellaneous.)
  • When using window envelopes, make sure the complete address is always visible, even when the insert moves.
  • Leave one space between words and two spaces between the state abbreviation and ZIP or ZIP + 4 .
