When you add a biller in the Bill Pay system, you will have the option of searching for them in the Bill Pay database, or entering their information manually to receive a check by mail. Only billers found in the database are registered with Bill Pay to receive electronic payments. Manually added billers will receive a check by mail.
Note: Selecting a registered biller does not guarantee electronic payment. For various reasons, your payment may be sent as check instead of ACH and vice versa. Payment method decisions are made after payment processing begins and can neither be set nor switched by humans (you or us).
