What is a Routing Number?

A routing number (also known as ABA which stands for American Bankers Association or RTN which stands for Routing Transit Number) is a nine-digit number that is used by banks or other financial institutions to identify where your account was opened in order to send or receive money.

Each bank will have its own specific routing number assigned to them to reduce the chances of miscommunication. In cases where the wrong routing number was provided during the transfer, it can cause your transaction to be delayed, or denied, and if it was approved, it could be transferred to the wrong account.
