ATLANTA – United Parcel Service announced Monday that 3,330 Mail Boxes Etc. franchises across the country will be renamed The UPS Store.

Atlanta-based UPS, which acquired Mail Boxes Etc. in 2001, said the change will let franchises lower prices for UPS air express, ground and international shipping service.

UPS said it tested The UPS Store name in St. Louis and Seattle and found that the change increased overall UPS shipping volume by 70 percent over the previous year.

“Research shows us that the UPS shield is as powerful on the storefront as it is on our package cars,” said Rocky Romanella, vice president of UPS Retail Services.

UPS said it has no plans to change the name of the 1,000 Mail Boxes Etc. stores outside the United States.
