Autozone EDI Compliance

AutoZone has been in business since 1979 and has over 5,000 stores located in the United States. The store has become the 2nd largest retailer of aftermarket auto parts and accessories.

AutoZone’s most sold items are their widely known car batteries and brake pads. Brake pads include Duralast, Duralast Gold, and Duralast Max. Other popular products include replacement parts, interior and exterior accessories, fluids and chemicals, tools and equipment, and a variety of performance products.

EDI documents are communicated over a connection protocol called a VAN (Value Added Network). Below are the EDI document types and labels that have been fully verified by CovalentWorks for accurate compliance with AutoZone’s EDI requirements. 

The ASN (Advance Shipping Notice) will contain comprehensive information about the packing of the products that are being sent to AutoZone and as well as transportation information. For example, the shipped date, shipped time, scheduled delivery date, measurement value, BOL number, PRO number, and tracking number will be included in addition to data that comes from the purchase order.

AutoZone uses the SOI format for ASN’s. SOI stands for Shipment, Order, and Item. SOI is also known as “summary ASN” and does not have as much carton detail information as some other ASN structures.

AutoZone uses a cross docking system that is a key component of their supply chain network. Cross docking is a logistics system in which products from a supplier are routed to stores through a distribution center. Trucks from suppliers dock on one side of the distribution center and trucks going out to the stores dock on the other side. Conveyer belts in the distribution center move product from the incoming docks to the outgoing docks by automatically scanning the GS1-128 bar code label. Product is not usually stored at the distribution center.

For Review:
