An ACH debit block is a fraud prevention tool offered by banks to protect bank accounts from unauthorized debits.

ACH Debit Block Extended Definition

When you have an ACH debit block in place on your bank account, you whitelist a company’s originating IDs so that they can withdraw money from your bank.

For example, you would whitelist your payroll company’s originating ID to withdraw money for direct deposit.
