Auto parts hub store count measures the enlarged retail locations that hold deeper assortments and support nearby stores with faster access to hard-to-find parts.

O'Reilly reported 399 Hub stores at the end of 2025. AutoZone reported 367 domestic and 53 international hub stores, with mega hubs forming a higher-inventory subset.

Hubs put slow-moving inventory closer to customer demand

O'Reilly said its Hub stores carry about 63,000 SKUs on average, with selected Hubs carrying up to roughly 115,000. AutoZone said standard hubs carry about 40,000 to 50,000 unique SKUs and mega hubs carry about 80,000 to 110,000.

That local depth supports commercial programs, where a repair shop may need an uncommon part within hours rather than days.

Hub count and DC count solve different supply-chain problems

Distribution centers replenish broad store networks. Hubs sit closer to stores and customers, shortening the last leg for less common parts.

A larger hub count is not automatically better. The right network depends on store density, SKU demand, geography, delivery frequency, and how much inventory per store the retailer chooses to hold locally.

Connect DIY and professional demand with commercial-service coverage, hub and distribution-center parts availability, inventory intensity and turnover, vendor funding, and store-level sales productivity.

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.
    Commercial Program CountDistribution Center CountHub Store CountCurrent concept
  • 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.
