Reminder: San Tan Valley Zip Code Changes Take Effect Tomorrow, July 1st


As previously reported, the United States Postal Service (USPS) is implementing changes to zip codes within the San Tan Valley area, and this change goes into effect tomorrow, July 1, 2023. This is a friendly reminder to residents in the affected areas to make the necessary updates to their mailing addresses.

Under the newly implemented changes, all addresses in Pinal County that have been using the zip code 85142 will transition to the new zip code, 85144. This move is aimed at optimizing mail delivery services due to the population growth and increased business activities in the region.

This change has an added effect – the zip code 85142 will no longer be associated with Pinal County or San Tan Valley. Instead, the 85142 zip code it will be exclusive to Maricopa County.

The areas mainly impacted by this change include San Tan Heights subdivision and the western region towards the San Tan Mountain Regional Park. However, residents should note that properties with the zip codes 85140, 85143, and 85132 are not affected by this change.

The USPS is facilitating the transition by continuing to deliver mail addressed with the old zip code, 85142, to San Tan Valley addresses until July 1, 2024. This is meant to provide ample time for residents to update their addresses with correspondents, subscription services, and others.

Residents are urged to immediately start using the new zip code, 85144, from July 1, 2023, to ensure efficient mail delivery. When purchasing new return address labels, stationary, or providing your address for any services or correspondences, please remember to use the new 85144 zip code.

If there are any questions or concerns regarding the zip code change, residents can reach out to The Postal Service AMS Office at 602.225.3460.

We encourage all San Tan Valley residents affected by this change to stay informed and make the necessary updates to help ensure a seamless transition. Keep in mind that this change is aimed at accommodating the growing community and improving mail delivery services for years to come.

Note: Those properties affected by this zip code change will still be located in San Tan Valley and should be using San Tan Valley, AZ 85144 as both their mailing and physical address. The only exception are the businesses on the "inside of the J-curve" such as Earnhardt, Dunkin, and the U-HAUL, as that corner was annexed into the Town of Queen Creek. While their zip code is also changing, they will continue to be Queen Creek, 85144. These addresses include the Goldmine Estates subdivision, Earnhardt Queen Creek, and U-Haul Moving & Storage. The rest of the addresses will use San Tan Valley, AZ 85144.
