ANSI X12
Quick answer
The dominant EDI standard in North America, used for commercial document exchange between B2B partners.
Key takeaways
- 850 - Purchase Order (equivalent to ORDERS)
- 855 - PO Acknowledgement (equivalent to ORDRSP)
- 856 - Advance Ship Notice / ASN (equivalent to DESADV)
- 810 - Invoice (equivalent to INVOIC)
- 997 - Functional Acknowledgement (technical confirmation)
What ANSI X12 is
ANSI ASC X12 is the EDI standard developed in the US, dominant in North America. It defines numbered transaction sets: 850 (order), 856 (ASN), 810 (invoice), 855 (order acknowledgement), equivalent to EDIFACT messages.
Common transaction sets
- 850 - Purchase Order (equivalent to ORDERS)
- 855 - PO Acknowledgement (equivalent to ORDRSP)
- 856 - Advance Ship Notice / ASN (equivalent to DESADV)
- 810 - Invoice (equivalent to INVOIC)
- 997 - Functional Acknowledgement (technical confirmation)
When it is relevant
If you work with US/Canada retailers or partners (Walmart, Amazon US, Target), you'll almost certainly use X12, not EDIFACT. Many European exporters need both.
How CRMconnect helps
CRMconnect supports both EDIFACT (Europe) and ANSI X12 (North America), mapping the same internal data into both standards - essential for companies exporting to multiple markets.
Real-world example
A European manufacturer also selling in the US sent EDIFACT in Europe but needed X12 850/856/810 for a US retailer. CRMconnect mapped the same internal orders into both standards, with no separate systems.

Frequently asked
Difference between ANSI X12 and EDIFACT?+
They are two parallel EDI standards: X12 dominates in North America, EDIFACT in Europe/Asia. They cover the same documents (order, ASN, invoice) but with different structures and names (850 vs ORDERS etc.).
What is transaction set 997?+
Functional Acknowledgement - the automatic technical confirmation that an X12 message was received and is structurally valid. The EDIFACT equivalent is CONTRL. It confirms technical receipt, not commercial acceptance.
Do I need X12 if I only sell in Europe?+
Not necessarily - EDIFACT/EANCOM dominates in Europe. X12 becomes necessary when working with North American partners. A good EDI module supports both for export flexibility.
