ACH Payments with Nacha Compliance

The ACH payments industry has accepted Nacha's new rule regarding 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 fundamental rule. The rule has been extended to include account validation for WEB ACH payments. Previously, Nacha mandated that all merchants who accept ACH have a commercially reasonable method to validate customers’ identity and routing numbersStarting 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, and 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 accepts ACH entries.

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


ACH Payments Account Validation: Purpose and Methods

Account validation goes a step further than just routing numbers in 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 helps ACH debit originators avoid mistakes right out of the gate, whether 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, increasing customer retention. Nacha does not prescribe a specific method for accounting validation but merely advises that the technique be commercially reasonable.


Options for Validating Customer Accounts


Microdepositing is the practice of depositing a small amount into the customer’s account. The customer will acknowledge the receipt of the amount, and the account will be considered validated. This method takes two to three days, dependent on the customer, for the completion of the validation process. The account cannot be validated if the customers fail to complete the process.


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. Still, Nacha rules require the merchant to wait a minimum of three days to submit actual payment information after sending the prenotification. The ACH payment delay remains an issue, just like microdeposits, owing to Nacha three-day rule.

Third-Party Validation

Merchants prefer this method since it eliminates customer dependency and payments delay. Third-party validation services have access to a pool of information 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 was identified in 2012 and has been a topic of discussion ever since.

Since originators are the point of initiation of a WEB debit transaction, the responsibility of account validation rests with them.
