The United States Postal Service location at 8155 N Black Canyon Hwy provides reliable mail and package delivery. Reviews note that the workers at this location are friendly, helpful, and provide really good customer service, contributing to a positive experience. However, service can be inconsistent. Some customers report disappointment with lost mail and receiving incorrect information. A significant concern is the long wait times, with lines often taking 20 to 30 minutes. Customers hope for more staff at the front to help, though it is noted that lines can also clear quickly during less busy periods. The site is bringing in an automated system for outdoor scanning and payment. A major issue raised is that the drive-up mail drop box is not accessible, presenting a trip hazard and failing ADA regulations, as customers must exit their vehicle to use it.
