Feature
As of April 14, 2024, Visa is assigning an enabler verification value (EVV) to payment enablers. Merchants who use a payment enabler for requesting authorization and OCT services must use the enabler ID value.
The EVV is an optional five-character hexadecimal value that Visa assigns to identify the payment enabler that processes requests for authorization and OCT services. If the wrong enabler ID is used in a transaction, the transaction is still accepted. If the enabler ID character string is longer than five characters, the transaction is declined.
The agent unique ID data is still supported in the TC 33 capture file in the first five positions:
  • Record: CP12 TCR1
  • Position: 138-148
The five positions that follow the agent unique ID in CP12 TCR1 are used for the EVV. The final position is reserved for 0. Except for the first digit which is fixed, CP12-TCR1 positions 138-148 () now occupy all of ISO field 126.18.
Merchants
When merchants use a payment enabler, this field must be included in an authorization or OCT request.
