Changes in four-digit zip code extensions

In 2001, the University moved to an address system that includes the use of the officially approved street addresses with new zip+4 codes for each building. We recently discovered that in a subsequent year, the U.S. Postal Service assigned new 4-digit zip code extensions to many University buildings, but KU was unaware of the change.

The Lawrence Postmaster informs us that the zip+4 codes posted on the USPS website at are official and should be used for all mailings. Units do not need to replace letterhead, business cards, etc., until current supplies are exhausted, however, any new letterhead, cards, or other publications should reflect the zip+4 code that appears on the USPS website. Mail is getting to its destination although there is a possibility that it may be delayed without the correct zip+4 code. We will also be correcting the zip+4 codes that appear in the Campus Buildings Directory and the University Federal Mail Address Designations list on the KU website. In the meantime, please check the USPS website for your correct zip+4 code.

Please share this information with members of your faculty and staff, and thanks for your cooperation.
