UPS said it is further expanding early morning deliveries to boost its competitive position.

The Sandy Springs-based shipping giant said it is adding hundreds more ZIP codes that can get deliveries by 8 a.m. and 10:30 a.m. UPS said it has offered “Early A.M.” service since 1994, expanded it to an additional 400 ZIP codes earlier this year and on Friday announced it is adding 766 more ZIP codes. The company said more than 87 percent of U.S. businesses can get the service.

Competitor FedEx has been expanding a similar service called “First Overnight.”

Industries that depend on morning deliveries include health care laboratories getting specimens to process test results for patients, legal and financial firms in need of urgent documents, parts manufacturers and mobile device repair services, according to UPS.
