EDI 943

Warehouse Stock Transfer Shipment Advice


What is an EDI 943?

An EDI 943 Warehouse Stock Transfer Shipment Advice is an electronic data interchange (EDI) document used by manufacturers and distributors in communication with third-party or remote warehouses. It’s mainly used to notify a warehouse when products are being sent to their location. 

EDI 943 documents follow the x12 format set by the American National Standards Institute (ANSI), a not-for-profit organization that regulates EDI formats in the U.S.

What are the Essential Components of EDI 943?

EDI 943 documents need to contain several pieces of data regarding an incoming shipment. These can include, but are not limited to:  

  • Date of Shipment 
  • Estimated delivery date 
  • Manufacturer identification information 
  • Ship-from location address 
  • Receiving warehouse information and address 
  • Carrier identification and contact information 
  • Shipment information, such as product SKUs/UPCs, quantity, weight, etc. 

How do I Use EDI 943?

When a manufacturer or distributor transfers stock to a remote warehouse or 3PL, they can use EDI 943 to alert the warehouse of the incoming shipment. This helps the warehouse to forecast and track inventory replenishment and prepare their docks for new shipments.  

While an EDI 943 document seems similar to an EDI 856 Advanced Ship Notice, the EDI 856 transaction is sent to customers, such as retailers. In contrast, EDI 943 is only used for remote warehouses. Therefore, these two documents cannot replace one another. 

After receiving EDI 943, the warehouse will respond with an EDI 997 Functional Acknowledgement.

What are the Benefits of EDI 943?

By using EDI 943, suppliers can quickly and easily alert their warehouse partners to upcoming deliveries. Because the transaction can be fully automated, it helps provide warehouses with near-real-time shipments data, which is essential for dock scheduling, labor planning and other receiving processes. Additionally, the electronic nature of EDI 943 helps prevent data errors, which are important for shipment reconciliation. 

Like other EDI documents, EDI 943 Warehouse Stock Transfer Advices are often protected by at-rest encryption, security protocols such as HTTPS and user authentications to protect your data. Using EDI software can also help create a virtual “paper” trail, which is useful in the case of any discrepancies from the receiving warehouse.
