When a Mistake in the Details Causes a Return
ACH payments rely on every field in the payment file being filled out correctly—routing numbers, account numbers, amounts, and other critical pieces of information. If even one field is missing, formatted incorrectly, or contains invalid data, the receiving bank may reject the transaction.
That’s when you’ll see ACH Return Code R69.
Let’s walk through what R69 – Field Error means, why it happens, and how you can fix it if it comes up.
What Does ACH Return Code R69 Mean?
ACH Return Code R69 stands for:
“Field Error.”
Here’s NACHA’s official definition:
R69 – Field Error: One or more fields in the ACH entry are either improperly formatted, contain invalid information, or are missing required data, and the Receiving Depository Financial Institution (RDFI) cannot process the entry.
In simple terms: there’s something wrong with the way the payment information was entered—and the bank couldn’t accept it because of that mistake.
Why Would an R69 Return Happen?
Here are some of the most common causes for an R69 return:
Missing required fields like account number, individual name, or company name
Improper formatting (e.g., wrong number of digits in an account number or routing number)
Invalid characters (such as symbols where only numbers are allowed)
Incorrect transaction codes that don’t match the payment type or account
Corrupted or incomplete ACH file submissions
Essentially, any key piece of information being wrong or missing can trigger an R69 return.
How to Handle ACH Return Code R69
If you encounter an R69 return, here’s what to do:
1. Review the Returned Entry
Look carefully at all fields—especially routing numbers, account numbers, names, ID numbers, transaction codes, and amounts. Identify the field that caused the error.
2. Correct the Error
Fix the missing, invalid, or incorrectly formatted information. Make sure everything is entered exactly as required by ACH file standards.
3. Verify the Data
Before resubmitting, double-check the corrected information. If needed, confirm details with the customer or payment recipient.
4. Resubmit the Payment
Once the fields are corrected, you can send the ACH transaction again.
How to Prevent R69 ACH Returns in the Future
You can minimize field errors by building stronger checks into your ACH processes:
Use ACH software that validates fields automatically before submission
Train your team on field formatting rules (e.g., number of characters allowed, no special symbols)
Require customers to submit complete and properly formatted bank information during onboarding
Test ACH files before sending large batches
Work with an experienced ACH provider that helps catch common formatting mistakes
Getting the small details right prevents big headaches later.
