What the 816 is
The EDI 816 — the X12 Organizational Relationships — is store, DC, and ship-to location hierarchies. It travels inbound for most trading programs.
When it's sent
The 816 travels outside the core 850 → 855 → 856 → 810 chain — it supports the programs that surround it.
Key segments
The 816 follows the standard X12 segment layout for its functional group. Partner companion guides add the specifics — EDISQ's certified maps carry those rules per partner, so you never read the implementation guide yourself.
