R20: Non-Transaction Account Explained
The R20 return code can be returned on either consumer or non-consumer accounts. ACH R20 indicates that the ACH entry was directed to an account that does not support transactions — such as a savings account, money market, certificate of deposit, or loan account. The Receiving Depository Financial Institution (RDFI) must return an R20 entry within 2 banking days of settlement.

What is an ACH Return Code?
An ACH return code is a standardized code used to explain why an Automated Clearing House (ACH) transaction was returned by the receiving bank.
Codes are issued by the RDFI and maintained by Nacha, the organization that governs the ACH Network. Certain codes may apply to consumer accounts, non-consumer (business) accounts, or both. These codes help banks, payment processors, and originators understand what went wrong during an ACH transaction so they can determine the appropriate next steps, such as retrying the payment, correcting information, or contacting the customer.
What Does R20 Mean?
ACH return code R20 means that the account is open and the number is valid, but the account type is not set up to receive or send ACH transactions. The issue is not with the account holder's identity, balance, or authorization — it's with the fundamental nature of the account. ACH is specifically desinger for transaction (checking) accounts.
Account Types That Trigger R20
Below are the account types that cause ACH R20:
- Savings accounts with transaction restrictions
- Money market accounts with limited ACH access
- Certificates of deposit (CDs)
- Loan accounts and lines of credit
- Investment and brokerage accounts
- Bank-specific restricted accounts (trust, custodial, escrow)
It is important to note that each bank has its own policies on which account types accept ACH.
When a Previously Working ACH Starts Returning R20
A common and underreported scenario: a customer provided a valid checking account, the ACH worked fine for months, then R20 returns begin.
This would have happened if the customer converts their account to a money market for better interest rates. Meaning, the account number is the same, but the account type would have changed.
To prevent this, always re-verify the account type when a R20 appears on a previously healthy payment relationship.
R20 vs Regulation D
Before 2020, Regulation D limited savings account transactions to 6 per month. The Fed suspended this limit in 2020, but many banks retained internal restrictions on ACH activity in savings accounts. R20 can still occur on savings accounts even though the federal 6-transaction cap no longer applies.
How to Fix an R20 Return
Tips to fix an R20 Return:
- Contact the customer and explain that the account type can't accept ACH
- Ask specifically for a checking account number
- Request a voided check to confirm account type
- Submit a new ACH entry
- Do not re-present the original against the non-transaction account
How to Prevent R20 Returns
Key preventative tips against R20 returns:
- At payment setup, explicitly ask customers to confirm they are providing a checking account (not a savings or an investment account)
- Include the account type as a field in your enrollment form
- Use instant account verification (IAV) to confirm account type before the first ACH submission
