After launching apparently successful pilot runs in San Francisco and New York, UPS announced today plans to expand its in-building delivery service to 10 additional U.S. cities. In mid-2019, the parcel service will be adding Atlanta, Chicago, Los Angeles, Houston, Dallas, Washington D.C., Philadelphia, Boston, Miami and Seattle to the list. UPS’s program was launched last summer, utilizing smart locks designed by New York-based startup, Latch.
