Amazon EDI Compliance Guide
Navigate Amazon's Vendor Central EDI requirements
Quick Answer
Amazon requires EDI 850 (Purchase Order), EDI 855 (PO Acknowledgment), EDI 860 (PO Change Request), EDI 856 (Ship Notice (ASN)), EDI 810 (Invoice), EDI 997 (Functional Acknowledgment) from all suppliers. Non-compliance triggers chargebacks including "Not Filled" PO confirmation shortfall: 5% of COGS; effective July 21, 2025 (reduced from 10%).
Amazon Vendor Central (1P) suppliers must comply with Amazon's EDI requirements for purchase order processing, shipping confirmations, and invoicing. Note: these requirements apply to Vendor Central (1P) suppliers, not Seller Central (3P) merchants. Amazon's system is highly automated and enforces strict data accuracy standards with automated chargeback systems, including Must Arrive By Date compliance windows.
Required EDI Transactions
Amazon requires suppliers to support the following EDI transaction types. Click any transaction to view our detailed guide with segment breakdowns and examples.
Amazon-Specific Transaction Requirements
- EDI 810 (Invoice): Invoices must match the PO and the ASN. Quantity or price mismatches turn into payment disputes that take weeks to resolve.
- EDI 850 (Purchase Order): Amazon transmits POs by vendor code and ship-to fulfillment center. Each PO carries delivery windows that drive downstream compliance, so capture them at intake.
- EDI 855 (PO Acknowledgment): Acknowledge every PO with accurate availability. Confirming units you later short-ship is what generates shortage claims, so the 855 needs live inventory data behind it.
- EDI 856 (Ship Notice (ASN)): Amazon expects the ASN before freight arrives at the fulfillment center, with carton contents matching what physically shipped. ASN accuracy feeds directly into shortage and chargeback calculations.
- EDI 860 (PO Change Request): Amazon adjusts open POs with 860 change documents. Quantity reductions and date shifts arrive this way, and your 855 and 856 must reflect the changed order, not the original.
Compliance Requirements
Here is what Amazon expects from EDI-compliant suppliers:
- EDI 850 Purchase Order processing via Vendor Central
- EDI 855 PO Acknowledgment with availability confirmations
- EDI 856 ASN with Amazon-specific routing data
- EDI 810 Invoice submission matching PO terms
- EDI 997 Functional Acknowledgment
- Amazon Vendor Central portal compliance
- ASIN-level product identification
- Prep and labeling per Amazon fulfillment center requirements
Chargeback Penalties
Non-compliance with Amazon's EDI requirements can result in significant financial penalties:
Common Amazon Chargebacks
- "Not Filled" PO confirmation shortfall: 5% of COGS; effective July 21, 2025 (reduced from 10%)
- Label and prep violations: $10 per box
- Oversized item violations: $25 per box
- Late or missing ASN: shortage deduction per shipment
- Routing non-compliance: carrier cost recovery charges
How to Set Up EDI with Amazon
- Get Vendor Central access. Amazon EDI applies to first-party (1P) vendors; third-party sellers on Seller Central use APIs instead.
- Open the EDI self-service setup inside Vendor Central and choose your connection method and identifiers.
- Map and test each document with Amazon's EDI self-testing flow, starting with the 850 and 997, then 855, 856, and 810.
- Complete Amazon's parallel testing period, where EDI runs alongside manual portal confirmation.
- Go live, then review chargeback and shortage-claim reports weekly to catch document errors early.

How to Achieve Amazon EDI Compliance
Getting compliant with Amazon requires three things: an EDI platform that supports all required transaction types, automated validation that catches errors before they trigger chargebacks, and integration with your ERP so orders flow through without manual re-entry.
EDI transaction formats follow ASC X12 standards, and product identification uses GS1 GTIN and GS1-128 barcode specifications. Both are required by virtually every major US retailer.
OrderSync handles all three compliance layers. Our platform processes EDI transactions (850, 855, 856, 810, 997) alongside PDF, CSV, and email orders through a single pipeline. Automated validation checks every order against your product catalog, pricing rules, and Amazon-specific compliance requirements before syncing to your ERP.

What is Amazon EDI?
Amazon EDI is the electronic document exchange Amazon runs with its first-party Vendor Central suppliers. Amazon sends purchase orders (850) and expects acknowledgments (855), advance ship notices (856), and invoices (810) in return, with 997s confirming receipt in both directions. It applies to vendors Amazon buys from directly, not marketplace sellers.
Does Amazon require EDI for Vendor Central?
Small vendors can confirm POs manually in the Vendor Central portal, but at any meaningful order volume EDI is the expected path. Manual confirmation does not scale past a handful of weekly POs, and portal-only vendors miss the automated 855/856/810 flow that keeps chargebacks down.
Do Seller Central (3P) merchants use EDI?
No. Marketplace sellers integrate through Amazon's SP-API or manage orders directly in Seller Central. EDI is specific to the Vendor Central (1P) relationship where Amazon is the buyer of record.
