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.

3. EDI 943 Format
Common information in the EDI 943 transaction includes:

5. 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.

By using EDI 943, suppliers can quickly and easily alert their warehouse partners to upcoming deliveries.

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.
