Old Dominion Freight Line is one of North America's largest less-than-truckload (LTL) motor carriers, operating over 260 service centers across the continental United States and generating over 98% of its revenue from transporting LTL shipments for diverse U.S. and North American customers through an integrated, non-union organization. The company competes in the highly consolidated LTL industry by emphasizing service quality, price, available capacity and reliability, while differentiating itself through faster transit times, efficient service center networks with next-day delivery capability, team driver models, superior geographic coverage and proprietary technology. Revenue is generated primarily through freight-costing systems that price shipments based on profitability, with customer engagement through tariffs, negotiated contracts and competitive bids; the company also offers value-added services including container drayage, truckload brokerage and supply chain consulting to supplement its core LTL operations.
