Property & Casualty Data Standards

ACORD P&C Standards

Property & Casualty Standards are available in two formats: AL3 and XML. AL3 is designed as a one-way, batch communication method for policy and commission data. AL3 Standards are available in an Access database, with a data dictionary and supporting documentation.

XML is constructed to support real-time requirements for business transactions via request and response messages. The XML standards are available in a fully indexed and searchable format. The main release components are:

  • Help File: Documentation for the XML Business Message Specification, also available in online format.
  • Support Files: Contains the XML Metadata file.
  • Schema Files: XML schemas used to validate an XML document.

Below are the most recent versions of the ACORD Property & Casualty Standards.
