Merchant handling

Actions to be taken

Do not infer a merchant action from this reserved value. Use the exact acquirer or processor specification that assigned the code before continuing the transaction.

This is conservative merchant guidance derived from the published response meaning. Current scheme, acquirer, processor, merchant advice, and transaction-specific rules take precedence.
