Check truncation entry return is a process that allows financial institutions to return check transactions that have already been processed. This can happen when there are issues with the check, such as insufficient funds or a stop payment.
The check truncation entry return process typically involves the return of the original check to the originating bank. This can be done through a physical return of the check or electronically.
A key benefit of check truncation entry return is that it helps to reduce the risk of fraud and errors in the check processing system. By returning checks that have issues, financial institutions can prevent further processing and potential losses.
Check truncation entry return can be initiated by either the originating bank or the receiving bank, depending on the specific circumstances of the transaction.
R11 Reasons
R11 Reasons are used to classify errors in the CTER process. The most common types of R11 reason codes are Duplicate Transaction, Incorrect Account Number, Incorrect Routing Number, Incomplete Information, and Unauthorized Transaction.
A Duplicate Transaction occurs when the same transaction is submitted to the CTER system. This can be prevented by ensuring that the same transaction is not submitted twice.
Incorrect Account Numbers and Routing Numbers can be corrected by updating the information in the CTER system. This is a common mistake that can be easily fixed.
Incomplete Information can be corrected by providing additional information. It's essential to ensure that all necessary details are entered into the CTER system.
Unauthorized Transactions can be prevented by implementing security measures to ensure that only authorized users can submit transactions. This helps to maintain the security and integrity of the CTER process.
Here are the most common types of R11 reason codes:
- Duplicate Transaction
- Incorrect Account Number
- Incorrect Routing Number
- Incomplete Information
- Unauthorized Transaction
Check Truncation Errors
R11 reason codes are used to classify errors in the CTER process, including duplicate transactions, incorrect account numbers, and unauthorized transactions.
The most common types of R11 reason codes include duplicate transactions, incorrect account numbers, incorrect routing numbers, incomplete information, and unauthorized transactions.

To correct R11 reason codes, update incorrect account numbers and routing numbers in the CTER system, provide additional information for incomplete information, prevent duplicate transactions by ensuring unique submissions, and implement security measures to prevent unauthorized transactions.
Here are the most common types of R11 reason codes:
- Duplicate Transaction – This code is used to identify the same transactions submitted to the CTER system.
- Incorrect Account Number – This code is used to identify wrong account numbers entered into the CTER system.
- Incorrect Routing Number – This code is used to identify wrong routing numbers entered into the CTER system.
- Incomplete Information – This code is used to identify incomplete information entered into the CTER system.
- Unauthorized Transaction – This code is used to identify unauthorized transactions submitted to the CTER system.
Mandatory Field Error
A Mandatory Field Error occurs when there's erroneous data or missing data in a mandatory field. This can happen when incorrect or incomplete information is provided.
This type of error can be frustrating for both businesses and customers. It's essential to understand the causes of Mandatory Field Errors to prevent them in the future.
Reviewing the types of errors that can occur in the Check Truncation Entry Return (CTER) process is crucial. This includes incorrect account numbers, routing numbers, incomplete information, duplicate transactions, and unauthorized transactions.
By understanding the type of error that has occurred, you can take steps to resolve the issue and prevent it from happening again. This includes reviewing your data and processes to ensure accuracy and completeness.
The ACH Return Code R26 specifically addresses Mandatory Field Errors. It's essential to familiarize yourself with this code and how it applies to your business.
R01 Insufficient Funds
If you're experiencing an R01 Insufficient Funds error, it's likely because the available and/or cash reserve balance is not sufficient to cover the dollar value of the debit Entry.
This error can be frustrating, but there's a solution. Try the transaction again up to two times within 180 days of the original authorization date.
R30 RDFI Not in Check Program
You've received an ACH return code R30, which is a pretty straightforward issue. The RDFI, or Receiving Depository Financial Institution, doesn't participate in a check truncation program.
This means they don't have the necessary systems in place to handle electronic check truncation. The good news is that this is a relatively easy fix.
To resolve the issue, you'll need to contact the RDFI and let them know they need to participate in a check truncation program. This will allow them to receive and process electronic checks more efficiently.
Once they're on board, you can resubmit the payment and it should go through without any issues.
R32 RDFI Non-Settlement

R32 RDFI Non-Settlement is a common issue that can occur during check truncation. The RDFI (Receiving Depository Financial Institution) is not able to settle the Entry.
This can happen when the RDFI is unable to verify the authenticity of the check or the account information. The RDFI is essentially saying, "I don't trust this transaction, so I'm not going to settle it."
The ACH Return Code R32 is a clear indicator that the RDFI has declined the transaction. It's essential to investigate the reason behind the decline to resolve the issue and prevent future occurrences.
In some cases, the RDFI may request additional information or verification to settle the transaction. This can cause delays and additional processing time.
Correcting Errors
Correcting errors is crucial in the check truncation entry return process to prevent delays and ensure security. Incorrect account numbers and routing numbers can be corrected by updating the information in the CTER system.
To correct incomplete information, you'll need to provide additional details. This can help prevent errors from occurring in the first place.
Duplicate transactions can be prevented by ensuring that the same transaction is not submitted twice. This is a common mistake that can be avoided with proper monitoring.
Unauthorized transactions can be prevented by implementing security measures, such as limiting access to authorized users. This will help keep your transactions secure and prevent unauthorized activity.
Once the errors have been corrected, it's essential to monitor the CTER system to ensure that the mistakes don't occur again. This will help you catch any new errors before they cause problems.
