What is ANSI X12 Standard?

On September 8, 2020 by Karthikeyan Mani Kannan

The ANSI X12 EDI standard was developed by the Accredited Standards Committee ( ASC ) in 1979. The ASC is a standards organization chartered and supervised by the ANSI ( American National Standards Institute ). The X12 standard was developed by ANSI to design uniform standards for the multi-industry electronic exchange of documents. While the ANSI X12 was initially developed to cater to various industries across North America, thousands of companies worldwide started using this EDI standard because of its increase in popularity. 

The X12 allows companies to transfer electronic documents without compatibility or security issues. The X12 maintains a standardized electronic data transfer system, improving the efficiency of communications between businesses. 

As one of the most commonly used EDI standards, the X12 is adopted across various industry verticals and regions. A prominent use case being the healthcare industry due to the HIPAA (Health insurance portability and accountability act) regulations in 1996. The HIPAA EDI transactions are based on the X12 EDI standard. 

Other main industries that are adopting the ANSI X12 EDI standard

• Insurance sector
• Government services
• Logistics industry
• Retail
• Finance sector

An essential feature of the ANSI X12 EDI standard is the detailed transaction set, which covers many common business transactions such as shipment notices, purchase orders, and so on. Each of these business transactions is assigned a three-digit number such as 810 for the invoice, 850 for the purchase order, 945 for warehouse shipping advice, etc.
