Data Elements

ISO 8583 defines data elements (DEs), which are individual fields that carry the information for an authorization message. Galileo interprets and relays some of the DEs to you in various output formats. Mastercard documentation refers to these fields as DE x, whereas Visa calls them Field x. Most Visa fields use the same numbering schema as Mastercard DEs, but in some cases they do not.

  • Some data elements are broken down into subelements (SE), and some subelements are further broken down into subfields (SF). In Galileo documentation the data elements are represented as DExxx with leading zeros, as necessary. For example, DE003 and DE048. Where there are subfields or subelements they are concatenated with the DE and they do not have leading zeros, so DE048SF5 and DE048SE61SF3. In the Mastercard DE column, the DEs are represented in different ways to assist with search engine hits, depending on how the search term is input.
  • Visa fields represent subfields as decimal numbers, such as Field 60.10. In Galileo documentation, only the DE is represented, unless the data element applies only to Visa transactions. In that case, the field number is provided.
  • Consult the documentation from each network for details on what the data elements contain.

This table shows where to see DEs that are present in authorization requests.
