Founded in 1972, UDS has operated for more than five decades, providing parcel and package delivery services to businesses across a range of industries.

UDS offers same-day delivery, next-day delivery, overnight delivery, and regional overnight delivery services. The company operates from 15 locations and handles approximately 150,000 deliveries with a reported 99.8% on-time rate. UDS serves a variety of industry verticals including automotive, floral, grocery, meal kits and perishables, office supplies, prescription drugs, retail and e-commerce, wine and spirits, payroll, banking, cosmetics, and small business logistics. Deliveries include visual proof of delivery (VPOD) and real-time text message updates for recipients.

Shippers commonly use UDS for time-sensitive, last-mile deliveries in the Chicagoland region, particularly for pharmaceutical, perishable, and retail e-commerce shipments where same-day or next-day service and delivery confirmation are important. UDS is a regional carrier, so its coverage is concentrated in the Chicago area rather than nationwide.
