What is X12?
ASC X12 , also called ANSI ASC X12, is a standard definition for EDI document exchanges. Most commonly used in the US, X12 has grown to over 300 defined transaction sets for business communication in industries such as healthcare, transportation, government, finance and more.
Most companies will have an X12 specification document that will outline the detailed intricacies of the files they will be sending. This is a useful reference to use when questions arise during X12 setup with a trading partner. Each transaction will be different and multiple transactions may be used depending on the business requirements. Each transaction has an assigned number, for example Invoice: 810; Purchase Order: 850; Advanced Shipping Notice: 856.
