What type of transaction requires a return code of R01?

• A. Insufficient funds
• B. Account closed
• C. Invalid account number
• D. Unauthorized transaction

Answer: (C)

The appropriate transaction requiring a return code of R01 is related to insufficient funds. This specific code indicates that the item was returned due to the account having insufficient funds at the time of processing. In the context of ACH transactions, when a debit attempt is made and the account does not have enough money to cover the transaction, the financial institution will return the item with the R01 code.

Understanding this return code is essential for those involved in processing ACH transactions since it directly impacts the handling of returns and notifications between financial institutions and their customers. The R01 code not only highlights a funding issue but also provides the originator with the opportunity to rectify the situation with their customer or take further action regarding the transaction.
