U.S. Post Office On-Site

Superior Storage is contracted by the U.S. Postal Service to operate a contract postal unit (CPU) that offers full service post office shipping services and stamp sales.  Our friendly staff is ready to help you with all your U.S. Postal service related needs, including helping you determine the most time and cost efficient ways to send your valuable shipments. 

Our Post Office hours are 9 to 5 Monday through Friday (closed form 1 to 2 for lunch), and from 9-12 on Saturday.  Daily collections are at 5:00 p.m. Monday through Friday, and at 12:00 p.m. on Saturday. 

For businesses and customers within two miles of our facility needing large quantities of stamps on a weekly or monthly basis, please ask us about our “Stamp Delivery Services” which can relieve you or someone from your office of the task of leaving your office or home to buy stamps.  Call us at 956-383-5474 if you would like to learn more about this service or any of our other U.S. Post Office Services.
