ASC X12, chartered by the American National Standards Institute (ANSI) in 1979, develops electronic data interchange (EDI) standards for national and global markets. With more than 315 X12 EDI standards and increasing X12 XML schemas, ASC X12 enhances business processes, reduces costs and expands organizational reach. Members include standards experts from health care, insurance, transportation, finance, government, supply chain and other industries.

The ASC X12 body comes together three times each year to develop and maintain EDI standards that facilitate electronic interchange relating to business transactions such as order placement and processing, shipping and receiving information, invoicing, payment and cash application data, and data to and from entities involved in finance, insurance, transportation, supply chains and state and federal governments. Committee members jointly develop and promote EDI standards that streamline business transactions, using a common, uniform business language. With more than 275 transaction sets, ASC X12 standards can be used to electronically conduct nearly every facet of business-to-business operations.

  • Provide high-quality standards that are responsive to the needs of the standards user and delivered in a timely manner.
  • Develop standards that are simple, efficient in use, and support as broad a user base as possible. The standards must be functionally specific and unambiguous to the standards user so that only one standard is available to satisfy the intended use.
  • Emphasize, as our primary responsibility, the development and maintenance of standards. However, we must also promote the expanded and proper use of the standards without interfering with the development and maintenance process.
  • Manage the evolution of EDI standards to accommodate change and introduce new technology while ensuring an orderly and acceptable transition within the existing user base.
  • Defined architecture with comprehensive and effective rules and procedures for standards development and maintenance and must dedicate ourselves to following the same.
  • Collaborate closely with other related standards bodies to avoid any duplication of effort, conflict, or confusion which may adversely affect the EDI user community.
  • Represent our user community in the development of the UN/EDIFACT standards, ensuring maximum compatibility with American National Standards. As our ultimate goal, we should strive for one set of EDI standards worldwide.
  • Adhere to the highest ethical principles.
