What Best Buy publishes on its Partner Portal about EDI, which documents must be in production before the first purchase order, how ship notices and labels work, and how Canada testing runs.
Overview
Who this is for: Consumer electronics and accessories vendors shipping to Best Buy distribution centers and stores in the US and Canada, and the EDI and logistics teams that support them.
Best Buy publishes its vendor shipping and EDI rules on the Partner Portal, a public site organized as guides for each inbound program: regional distribution centers (RDC), DDC distribution centers and direct to store (DTS) shipments. Most of the operating detail is public, while the EDI implementation guides, standard terms and some program pages need a portal account managed by each vendor's security administrator.
The rule that shapes every Best Buy project is simple: six EDI documents must be in production before Best Buy cuts the first purchase order. They are the purchase order, purchase order change, invoice, application advice, advance ship notice and functional acknowledgment. Testing for all of them is coordinated with Best Buy's EDI team, and vendors new to EDI are asked to contact that team before they receive a Best Buy vendor number.
Ship notices carry most of the operational weight. Best Buy's distribution center guides set the 856 at X12 version 4030, require an ASN for every shipment, define how many ASNs a truckload, LTL or parcel shipment needs, and tie each one to SSCC labels. This guide records what the public pages say and when we checked, and lists what needs a portal login.
Requirements at a glance
Best Buy publishes its inbound and EDI rules on the Partner Portal by program: regional distribution centers (RDC), DDC distribution centers and direct to store (DTS). Six X12 documents are mandatory before the first purchase order, and the distribution center guides set the 856 at version 4030 for core domestic shipments. Full implementation guides need a portal login. We checked the public pages on October 31, 2026.
Public shipping guides, receive-ready document rules and vendor standards; implementation guides and standard terms need a login from the vendor's security administrator.
Business units and channels
Large retailers often handle each business unit or channel as a separate EDI relationship, with its own documents, guides and setup. Confirm with Best Buy which of these you supply before mapping.

Workflows
The steps summarize the documents below. Where a step is not in Best Buy's published documents, it reflects common practice.
Documents and APIs
Every document this guide names, with the program it applies to and its status. Required, optional and conditional come from Best Buy's published documents cited below; documents marked general guidance are common in this industry but not confirmed for Best Buy.
| Document | Name | Direction | Program | Status | Purpose |
|---|---|---|---|---|---|
| 850 | Purchase Order | You receive from Best Buy | Direct to store | Required | Best Buy's order. Vendors must not accept verbal orders unless an 850 confirms them. |
| 860 | Purchase Order Change | You receive from Best Buy | Direct to store | Required | Changes to an open purchase order; must be in production before the first PO. |
| 810 | Invoice | You send to Best Buy | Direct to store | Required | One invoice per purchase order, transmitted on the day of shipment. |
| 824 | Application Advice | You receive from Best Buy | Direct to store | Required | Best Buy's response on documents the vendor sent; must be in production before the first PO. |
| 856 | Advance Ship Notice | You send to Best Buy | Direct to store | Required | Required for every shipment, sent at the time of shipping, with SSCC-18 labels on all shipments. |
| 997 | Functional Acknowledgment | Both directions | All vendors | RequiredWithin 24 hours of each Best Buy document | Vendors must acknowledge Best Buy's documents within 24 hours. |
Read from top to bottom. Solid arrows are documents Best Buy names in its own public documentation; the dashed arrow is the acknowledgment. The order is typical, not a Best Buy rule: programs such as vendor direct to consumer use their own documents and timing.
Document by document
For each document: what it does for you as the supplier, what Best Buy's own documents say about it (with the source and its date), and general EDI practice that helps, labelled as such. Your Best Buy mapping guide for your version is the final word on fields and codes.
Best Buy's order, which must be in production before the first purchase order. Verbal orders are not valid without one.
Changes to open orders arrive as an 860, which is also mandatory before the first purchase order.
An ASN is required for every shipment and is sent when the shipment leaves. The count of ASNs depends on the shipment type.
Best Buy expects a separate invoice for each purchase order, sent the day the goods ship.
A 997 confirms a document arrived and passed standards checks. Best Buy sets a 24-hour limit.
Deductions
The public pages we read state one set of fees, for freight moved outside Best Buy's carrier program. ASN violations are tracked but not charged during a transition period, and Best Buy says a chargeback program may follow.

Challenges
The 850, 860, 810, 824, 856 and 997 must all be tested and in production before Best Buy cuts the first purchase order.
Each truckload, LTL pallet or parcel needs the right number of ASNs, sent at shipping and before the truck reaches the yard.
SSCC labels are required on every shipment, a number cannot be reused within 18 months, and DDC pallets allow one SKU per SSCC.
