UN/EDIFACT is a set of regulations defined and continually adapted by the United Nations specifically developed for the electronic data exchange. It establishes the norms for business and trade processes and counteracts proprietory standards within specific industries.

UN/EDIFACT is applied world-wide and enables the process integration between software programs of all participating companies.

Data regulation processes have been developed for specific business applications, such as bid submitting, awarding of orders or contracts, confirmations, completing customs or transportation forms, billing, payment settlement, etc. These regulations refer to the data use patterns and the syntax for the structure of the electronically transmitted messages.
