Target Corp. is broadening its next-day delivery service to an additional 20 metropolitan areas, increasing the total number of cities where customers can receive online orders rapidly to over 50.

The nation's eighth-largest retailer by revenue announced Tuesday during its fourth-quarter earnings presentation that it will be rolling out next-day delivery to more locations in the spring. This expansion is part of its ongoing strategy to transform stores into mini-fulfillment centers. The increased reach of this service will make next-day delivery accessible to 60% of the U.S. population.

According to a Target fact sheet, faster delivery is coming to cities such as Birmingham, Alabama; Santa Barbara, California; Fort Myers, Florida; and Honolulu. Currently, Target offers next-day delivery in approximately 35 major markets.

Target (NYSE: TGT) states that two-thirds of its digital sales are fulfilled on the same day through drive-up services, in-store pickup, or same-day delivery for Target Circle 360 members.
