Auto parts distribution center count measures the primary warehouse network used to replenish stores and support broad parts availability.

O'Reilly operated 32 distribution centers at December 31, 2025, totaling about 14.0M operating square feet. AutoZone reported 16 distribution centers at August 30, 2025: 13 in the U.S., two in Mexico, and one in Brazil.

Count alone does not measure distribution capacity

A distribution-center network differs by building size, automation, service radius, inventory depth, shipment frequency, and the number of stores it supports.

O'Reilly said its DCs stock more than 156,000 SKUs on average and provide five-night-a-week delivery to substantially all stores. AutoZone supplements its DC network with hub stores that push expanded assortments closer to local demand.

Supply-chain design affects store inventory requirements

A denser or faster replenishment network can support high parts availability without placing every slow-moving SKU in every store.

That is why distribution-center count should be read with inventory per store, not used as a simple scale ranking. More DCs can reflect geography or network design rather than superior economics.

Where this concept fits
  • Commercial coverage and parts-availability networkCurrent relationship
    Commercial program count shows how much of the store base can directly serve professional accounts, while hub stores and distribution centers position broader assortments at different points in the replenishment network. The counts are architecture inputs, not standardized service-quality scores.

  • DIY, professional, and store productivity
    DIY sales and professional sales separate the two main customer jobs served by the auto-parts store network. Sales per average store and sales per average square foot show how that customer mix converts into unit and space productivity without replacing comparable-store growth.

  • Inventory intensity, turnover, and vendor funding
    Inventory per store shows local working-capital intensity, inventory turnover shows how quickly cost of goods sold cycles through average inventory, and accounts payable to inventory shows how much supplier credit offsets the inventory balance. Together they frame the tradeoff between parts availability and capital efficiency.
