Yes, we believe the ACH return code R20 is the most appropriate for an external transfer to or from an account that prohibits external transfers. R20 is the designated ACH return code for payments sent to non-transaction accounts as defined in Regulation D, which includes “an account against which transactions are prohibited or limited.” Even though this interest-bearing checking account is a transaction account under Regulation D (since it allows unlimited internal transfers — unlike non-transaction accounts which permit no more than six internal or external transfers), we believe that return code R20 “most closely approximates the reason for [r]eturn,” since the return is being made due to transaction limitations on the account.
Regarding external paper checks and remotely created checks (RCCs) processed through the check collection system, we recommend reviewing return code Q in the Specifications for Electronic Exchange of Check and Image Data adopted by the Federal Reserve (DSTU X9.37-2003). We believe that return code Q may be used for unauthorized items.
