Oftentimes, you will see a transaction come through with a final status of CORRECTION instead of FUNDED. The money has funded, but there was something incorrect on the account info entered, so you will need to send the next transaction with the correct account info or it will come back as an X code.
The corrected information will display within the details of the PDC reporting. Usually this occurs when a bank has bought out another bank and is transitioning the account to the new bank's routing number info and/or account info.
C01 Incorrect Account Number
C02 Incorrect Routing Number
C03 Incorrect Routing and Account Number
C04 Incorrect Account Name
C05 Incorrect Trans Code
So, if you receive an ACH transaction with the status of CORRECTION, and for example in the transaction details, Status Description, it has C01XXXXXX, all the numbers behind C01 are the updated account number that should be used next time.
