What is an 835?

An 835 is a remittance advice in an EDI X12 (Electronic Data Interchange) data format. This format is based on The Accredited Standards Committee (ASC) X12 standards. It is used to exchange specific data between two or more trading partners. If you are not familiar with the 835 format, you will want to use the PDF RAs.
