What is the difference between X12 and EDIFACT?
They are two EDI standards for the same purpose, split by geography. ANSI X12 is used across North America and numbers its documents — 850 for a purchase order, 856 for a shipping notice. UN/EDIFACT is the international standard and names them instead, so a purchase order is an ORDERS and a despatch advice is a DESADV.
A brand selling into North America and Europe will meet both. The documents carry equivalent information, so the work of supporting the second standard is mapping and testing rather than rethinking the process.
