When the Receiving Bank Can't Process All ACH Transactions
Most of the time, ACH transactions move money smoothly between banks in the U.S.—whether you’re handling payroll, recurring billing, or vendor payments. But not all banks are fully equipped to handle every type of ACH entry. Some financial institutions are part of the ACH network in a limited capacity.
When a receiving bank doesn’t support the type of ACH transaction you’re sending, you might see ACH Return Code R34. It’s not about account problems or customer authorization—it’s about the bank’s capabilities.
Let’s break down what R34 – Limited Participation DFI means, what causes it, and what your business can do to resolve it.
What Does ACH Return Code R34 Mean?
ACH Return Code R34 stands for:
“Limited Participation Depository Financial Institution.”
Here’s the official NACHA definition:
R34 – Limited Participation DFI: The Receiving Depository Financial Institution (RDFI) does not participate in a specific type of ACH transaction you attempted to send.
In other words, the bank receiving the payment is in the ACH system—but doesn’t handle the particular class of transaction you tried to send (for example, international ACH entries, check conversions, or corporate transfers).
Why Would an R34 Return Happen?
You may get an R34 return if:
The receiving bank does not accept international ACH transactions (IAT)
The RDFI is not set up to receive check truncation entries (XCK)
The bank doesn’t support corporate entries like CCD or CTX
The transaction used an SEC code (Standard Entry Class code) not supported by that institution
The RDFI only participates in the ACH network on a limited basis
This is more common with small or regional banks, credit unions, or special-purpose financial institutions.
How to Handle ACH Return Code R34
If your ACH transaction is returned with R34, here’s how to respond:
1. Confirm the SEC Code Used
Identify the type of transaction you attempted to send—was it a CCD, CTX, IAT, or XCK entry? This will help determine why the receiving bank rejected it.
2. Contact the Receiving Party
Let your customer, employee, or vendor know that their bank isn’t able to receive this type of ACH entry. Ask if they have an alternate account or bank that can.
3. Request Updated Payment Information
If they do have another bank account at a fully participating DFI, ask for new routing and account details—and get proper authorization to use them.
4. Reformat the Transaction (If Applicable)
In some cases, you may be able to reprocess the transaction using a different SEC code—if permitted by NACHA rules and if the customer approves.
5. Consult Your ACH Provider
If you’re unsure how to proceed, your payment processor can help determine what the RDFI does or doesn’t support and guide you through the next steps.
How to Prevent R34 Returns in the Future
While R34 errors are relatively rare, here are some tips to avoid them:
Verify the receiving bank’s ACH participation level when onboarding customers or vendors
Use bank verification tools that check for SEC code support
Flag and review returns regularly so you can spot trends with certain institutions
Educate your customers or partners on what’s required for ACH processing on their end
It’s especially important to be aware of this if you deal with government entities, non-traditional banks, or international partners.
