American National Standards Institute
The American National Standards Institute (ANSI) is a non-profit organization that controls the development of standards for processes, services, and products in the United States. ANSI also synchronizes U.S. standards with international standards so that American products can be used all over the world.
Accredited Standards Committee X12
In 1979 ANSI chartered a standards organization Accredited Standards Committee X12 (ASC X12) to create and maintain EDI standards and XML schemas. ASC X12’s membership comprises 3,000 standard experts representing over 600 companies from various industries. ASC X12 Membership is open to any organization, company, or even individual, who directly and materially affected by ASC X12 activities. The members of ASC X12 have to pay annual membership dues.
What is EDI ANSI ASC X12 Standards?
The ANSI ASC X12 Standards is sometimes called the EDI ASC X12, ANSI X12, ASC X12, or simply the X12 Standard. X12 is a set of standards and rules that determine a specific syntax for structuring and transferring electronically business documents between partners. There are different types of business documents in EDI, which often are called “Transaction Sets”.
ASC X12 Transaction Set
The Transaction Set – is a single business document such as a Purchase Order, Invoice, Student Educational Record (Transcript), Healthcare claim, Ship Notice (ASN). There are hundreds of Transaction Sets available in the ANSI ASC X12 standards. Each set of transaction data is identified by a 3 digits code number:
ASC X12 Structure
Many X12 transaction sets have 3 parts. The segments that can be used in each of these parts in a particular document (such as an invoice) are listed in the related tables defined in the X12 standards document. For example:
ASC X12 Segments and Sequence
The following Purchase Order example, shows which segments can be used in the transaction set and the desired sequence of segments:
ST Transaction Set Header
BEG Beginning Segment for Purchase Order
REF Reference Identification
PER Administrative Communications Contract
TAX Tax Reference
FOB F.O.B. Related Information

• A transaction in an X12 document, always begins with the Transaction Set Header (ST) segment
• A transaction in an X12 document always ends with the Transaction Set Trailer (SE) segment
