DE003 Codes

The first two digits of DE003 (Mastercard) or Field 3 (Visa) contain the processing code. This code indicates the type of transaction. The remaining four places indicate the types of accounts involved (to and from).

Galileo exposes the processing code in several contexts. The raw contents of DE003 are available by request in the de003 field in some Authorization Events API webhook messages:

In other contexts, Galileo transforms or translates the processing code:

• Auth API — DE003 is translated into the user-friendly English descriptions in auth_type and transaction_type.
• Events API — The processing code in auth_tran_type in the Authorization Event messages has been transformed as shown in this table.
• RDFs — DE003 information is displayed in the RDFs as follows:
  • TRANSACTION CODE — Displays the first two digits of DE003 except for the transformations shown in this table.
  • OTC FLAG — DE003SF1 is 17 for Mastercard and for Visa it's 01 plus MCC 6010.
  • IS AFT TRANSACTION – Visa only. Is Y when Field 3.1 is 10.

Positions 1–2

Processing code. The descriptions show the general meaning of these codes. Each network might have its own specific use for a processing code, and not all networks use all of these codes. Consult the documentation from each network to see how the codes are used.

Positions 3–4 and 5–6

Positions 3–4 are the sending account and positions 5–6 are the receiving account.

auth_tran_type values

This table shows how the value in DE003SF1 is transformed into the auth_tran_typevalue in the Authorization Events messages.

TRANSACTION CODE values

This table shows how the value in DE003SF1 is transformed into the TRANSACTION CODE value in the Authorized Transactions RDF.
