NEW YORK – CNBC reports that McDonald’s is planning to expand its food delivery service from roughly 3,700 U.S. locations to 5,000 by the end of the year.

"We're learning a lot about delivery and seeing success in dense urban metros with commerce, like New York, Boston, Miami and Los Angeles," Chris Kempczinski, president of McDonald's USA, said on Tuesday. "I truly believe we're just beginning to scratch the surface on this opportunity."

The news source notes that earlier this summer, McDonald’s CEO Steve Easterbrook said delivery was available at more than 2,000 locations, and he expected McDonald's partnership with UberEats to expand to more than 3,500 locations by the end of June. In the United States, 60% of McDonald's delivery orders are placed in the evening or late at night, and arrive, on average, within 30 minutes, he said.

CNBC notes that McDonald's already has well-established delivery services in Asia and the Middle East, where for some restaurants delivery represents 40% of sales. In 2016, the burger chain brought in nearly $1 billion in delivery sales globally.

The restaurant industry has a keen focus on food delivery, suggests the news source, with third-party services like Uber, Postmates and DoorDash offering up their drivers and services. Recently, Facebook announced the expansion of its foray into food delivery.
