ACH Payments with Nacha Compliance

The ACH payments industry expected NACHA’s new rule with regards to WEB debits since it was first proposed in November 2018. The new rule went into effect on March 19, 2021. However, the rule will not be enforced until the end of one year from the effective date, provided the covered entities can prove their plans towards compliance in good faith.

Nacha’s New Rule for WEB Debits

Take heed to note that NACHA has not changed the entire rule. The rule has been extended to include account validation for WEB ACH payments.

Previously, NACHA mandated all merchants who accept ACH to have a commercially reasonable method that validates customer’s identity and routing numbers.

Starting March 19, 2021, the terms commercially reasonable method shall include, at minimum, account validation.

Note that the rule applies prospectively, not retroactively. Nacha requires account validation for WEB Debits on accounts being used for the first time or changes in an existing account number.

This means ACH recurring payments will require validation only for the first time the payment is processed.  This rule change will not require validation for subsequent transactions.

Remember, though, that the ownership of the account is not required to be validated. NACHA requires an originator to, at minimum, confirm that the account is open, and the account accepts ACH entries.

While this change may possibly involve re-tooling the fraud detection systems for most ACH originators, it brings several benefits. These include reduction in the volume of invalid or fraudulent transactions, limiting the effect of fraud events, and improved front-end fraud detection capabilities.

ACH Payments Account Validation: Purpose and Methods

Account validation goes a step further than just routing numbers in the process of validating payments. Validating an account offers the originator an insight into the account’s current standing.

Account validation enhances accuracy by mitigating errors in the account, transit, and routing numbers which otherwise cost the company and damage the brand. Validating accounts help ACH debit originators avoid errors right out of the gate, whether they are accidental or fraudulent.

Verification of checks and accounts in this manner improves relationships with employees, vendors, and customers. It also reduces the volume of help desk calls, thereby increasing customer retention rates.

NACHA does not prescribe a specific method for accounting validation but merely advises that the method be commercially reasonable.

Let’s look at our available options  validating customer accounts.


A small amount transfers to the customer’s account. The customer will acknowledge the receipt of the amount, and the account will be considered as validated.

This method takes two to three days, dependent on the customer for completion of the validation process. If the customers fail to complete the process, the account cannot be validated.


Prenotifications eliminate the customer dependency inherent to microdeposits. Account validation with prenotifications involves initiating a $0 transaction through the ACH network.

The account confirmation may take two to three days, but NACHA rules require that the merchant wait a minimum of three days for submitting actual payment information after sending the prenotification.

The ACH payment delay remains an issue, just like microdeposits, owing to NACHA’s three-day rule.

Third-Party Validation

Merchants prefer this method since it eliminates both customer dependency and delay in payments.

Third-party validation services have access to a pool of information that they can use to understand the account’s current standing, history of fraud, forgery, NSFs, paperhanging, owner authentication, identity verification, and counterfeiting or check alterations.

NACHA’s new rule does not come as a surprise. A need for the rule had been identified back in 2012 and it had since been a topic of discussion.

This rule aims to curb the volume of fraudulent transactions before they enter the ACH Network. It protects RDFIs from posting fraudulent, incorrect, or unauthorized payments. Since originators are the point of initiation of a WEB debit transaction, the responsibility of account validation rests with them.
