What is AS2?

AS2, or Applicability Statement 2, allows users to facilitate critical business processes including EDI exchanges or other data, such as XML, CSV, or plain text documents, over the internet. Through a client-server relationship for point-to-point connectivity, AS2 creates an “envelope” for sensitive business data, allowing it to be sent securely.

A Brief History of the AS2 Protocol

  • Developed in the U.S. by the Uniform Code Council (UCC).
  • Much of the success of AS2 has been seen in America, notably the retail sector.
  • A large influence behind the adoption of AS2 was in 2002 when retail giant Walmart mandated its 10,000 suppliers use AS2 to exchange EDI data with them directly.
  • Today, AS2 is used widely across a large number of industries.

Compare AS2 and FTP

Industry mandates directing the use of one protocol or technology versus another often arise from the history of implementation, industry use, and market penetration. To illustrate, we’ll compare one advanced protocol and the VAN:

  • The VAN was conceived in the early stages of electronic communication

  • AS2 is a modern file-based integration and EDI protocol

  • The VAN acts like a post office for routing business transactions

  • AS2 allows your business to go direct
