Merchant handling

Actions to be taken

Do not provide the goods or services on this authorization. Ask the cardholder for another payment method or follow the acquirer’s instructions; do not automatically retry from the response code alone.

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