Stock Transfer Shipment Advice
What is EDI 943 – Warehouse Stock Transfer Shipment Advice?
EDI 943, known as the Warehouse Stock Transfer Shipment Advice, is an electronic document used to notify third-party logistics providers (3PLs) or remote warehouses about an incoming stock transfer. It plays a crucial role in warehouse communication, allowing manufacturers and distributors to alert their warehouse partners before a shipment arrives.
This transaction follows the ANSI X12 EDI standard, ensuring structured and reliable communication between systems. Unlike EDI 856 (used for notifying customers), EDI 943 is specifically used for internal stock movements between locations or to outsourced warehouse partners.
At Vraja Technologies, we integrate EDI 943 seamlessly within your Odoo ERP, helping streamline communication with 3PLs and automate warehouse operations.

Key Components of EDI 943
An EDI 943 document provides detailed shipment information that allows a warehouse to prepare for receiving and managing inventory effectively. Typical data elements include:
Date of Shipment
The date the stock is dispatched.
Manufacturer or Supplier Identification
Details of the organization sending the stock.
Receiving Warehouse Information
Destination warehouse or 3PL details.
Shipment Line Details
Product SKUs, UPCs, descriptions, weights, and quantities.
Estimated Delivery Date
Expected arrival time at the warehouse.
Ship-From Location Address
Origin of the stock transfer.
Carrier Information
Including contact details and identification number.
This structured data enables receiving warehouses to plan ahead and align inventory systems efficiently.
How is EDI 943 Used?
When a supplier or manufacturer is sending stock to a remote warehouse, EDI 943 is used to notify the receiving party in advance. This early communication is critical for:
- Dock scheduling and unloading preparation
- Inventory forecasting and space planning
- Avoiding delays and manual entry errors
Although it may seem similar to an EDI 856 (Advance Ship Notice), EDI 943 serves a different purpose. While EDI 856 is sent to retailers or customers, EDI 943 is strictly for warehouse operations and stock transfer coordination.
After receiving an EDI 943, the warehouse typically sends back an EDI 997 Functional Acknowledgement to confirm receipt.
