EDI 846
Inventory Inquiry/Advice
What is an EDI 846?
An EDI 846, also known as an Inventory Inquiry/Advice, is an electronic document used to share real-time updates about inventory levels between trading partners. It can be sent by both buyers and sellers to communicate product availability, stock quantities, and restocking information.
ย
This EDI transaction is especially common in drop-ship environments, where retailers manage online storefronts and need up-to-date supplier inventory without relying on manual portals or API integrations.
The EDI 846 follows the ANSI X12 standard set by the American National Standards Institute (ANSI), which defines EDI formatting for electronic business documents across industries.ย

What are the Essential Components of EDI 846?
An EDI 846 document provides key details about current or forecasted inventory. Common data elements include:
- Inquiry date and time
- Retailer and vendor identification
- Product identifiers (SKU, UPC, GTIN, etc.)
- Unit of measure
- Quantity on hand and quantity available
Suppliers can also include:
- Forecasted restock or replenishment dates
- Inventory levels by location or warehouse
- Notices of discontinued or back-ordered items
This information ensures both parties have accurate, timely insight into product availability across the supply chain.

How do I Use EDI 846?
The EDI 846 is bi-directional, meaning either the buyer or the seller can send it.
When sent by a retailer:
- Used to request information about supplier stock levels.
- Often transmitted multiple times a day to keep eCommerce listings up-to-date.
- Helps avoid overselling and ensures product availability is visible to customers in real time.
When sent by a supplier:
- Used to share current inventory, expected replenishment, or discontinued items.
- Automatically updates retailer systems or websites with accurate stock status.
- Supports smoother drop-ship and omnichannel fulfillment.
What are the Benefits of EDI 846?

For retailers
The EDI 846 makes it easy to request or receive up-to-date product availability information from suppliers. This helps keep eCommerce storefronts accurate, reducing overselling and improving customer experience.
For suppliers
