What’s Happening
An ACH prenote is a zero-dollar test transaction used to verify bank account details before real money moves through the Automated Clearing House network.
Think of it like sending a postcard to confirm an address—except here, you’re confirming a bank’s routing number and your account number. The bank receives the prenote, checks if the account exists and is active, then sends a validation signal back to the sender. No cash exchanges hands. Usually, the prenote takes 2–3 banking days to process. According to Nacha, the ACH network operator, prenotes cut failed transfers by over 70% when used correctly Nacha.
Step-by-Step Solution
To send or verify an ACH prenote, follow a 5-step process using payroll or accounting software.
First, grab the recipient’s routing number, account number, and account type (checking or savings). Enter those details exactly as they appear on a voided check or bank statement. In most payroll systems—ADP, QuickBooks, Gusto, Workday—flip on the “Send Prenote” option under the direct deposit or bank info section. The system then submits a $0 ACH credit. You’ll get confirmation within 2–3 banking days. If the status shows “Received” or “Settled,” you’re good to go. If it comes back as “NOC” (Notification of Change) or “Returned,” fix the data and try again. A 2025 CFPB study found 42% of prenote issues start with typos in the account number Consumer Financial Protection Bureau.
