To get a voided check online, log into your online banking account and look for an option like “Direct Deposit Forms” or “Voided Check Request.” Various banks have downloadable versions that contain your account and routing numbers in actual check format. If you don’t have this option with your bank, then ask for a direct deposit authorization form with your bank info on it. Alternatively, get in touch with customer support. Always make sure the downloaded or printed document is secure and clearly marked as “VOID.”
