ANSI X12 is a set of standards for electronic data interchange (EDI) that facilitates the exchange of business documents between organizations. Developed by the American National Standards Institute, these standards define the format and structure of various transaction sets, such as invoices and purchase orders, ensuring that different systems can communicate effectively. The ANSI X12 standards are widely used across various industries, including retail, healthcare, and transportation. By standardizing the way data is formatted and transmitted, organizations can streamline their operations, reduce errors, and improve efficiency in their business processes.
