EDI for Amazon — full spec, timelines and integration
In short: Amazon requires suppliers to exchange EDI 850 (PO), 855, 856 (ASN with SSCC), 810, 820, 846 (Inventory Advice), 997 via EDI. This page covers the Amazon EDI spec, AS2 or SFTP transport, mandatory chargeback SLAs, ASN/label requirements, and how to get compliant in 2-4 weeks with a pre-built Amazon template on EDIconnect.
Key capabilities
- Pre-built Amazon spec: Every mandatory field, code, envelope value and validation rule from the current Amazon EDI implementation guide.
- Chargeback-safe ASN: GS1-128 SSCC label generation, pack hierarchy, timing rules — the exact combination that survives Amazon's DC receiving.
- AS2 or SFTP transport included: Certificates, endpoints and connection testing with Amazon's EDI/VAN team — end-to-end, not just software.
- Live in 2-4 weeks: From contract to first production PO with Amazon — mapping, testing and go-live handled by EDIconnect.
Amazon EDI onboarding — the critical steps
Amazon's vendor onboarding is compressed and unforgiving: from vendor-code assignment to first production PO is typically 2-6 weeks, and any EDI failure delays merchandising launch. The winning pattern: assign the EDI spec to an experienced provider on day 1, run integration tests in parallel with item setup, and be certification-ready before the first PO drops.
EDIconnect's Amazon template has been in production with dozens of suppliers — the spec quirks, the label format edge cases, the SLA windows are all pre-configured. Suppliers we've onboarded typically hit zero chargebacks in the first 90 days.
