- The U.S. Postal Service plans to launch 14 sorting and delivery centers on Nov. 1, including seven in California, the agency announced in an industry bulletin.
- The large-scale facilities will aggregate work previously handled by delivery units within their areas. Delivery units are the final stop for packages and mail before the Postal Service delivers them to end customers.
- The Postal Service currently has Post Office locations at the planned launch sites, per the agency’s website. However, the conversion to sorting and delivery centers will not result in any Post Office closures or changes to retail or PO Box delivery services, according to the industry bulletin.
