Use MCC 7322 and follow Visa's debt rules
Visa introduced MCC 7322 for collection agencies in October 2022 and made it mandatory from 15 April 2023. Its rules bar repaying debt with credit or charge cards, bar debit cards for payday loan repayments, require a written agreement with the cardholder for time-barred debt and cover overdue receivables as well as traditional debt. Build your payment page to accept only the cards these rules allow.
