Credit Union Routing Numbers

The Bank Routing Number, sometime referred as ABA Number, is a 9 digit number assigned by the American Bankers Association (ABA) to uniquely identify the bank on which payment is drawn. The bank routing number is also referred as check routing number because it generally appears at the bottom of your check leaflet.

Your routing number identifies the location where your account was opened. You’ll often be asked for your checking account routing number when you’re making a payment online or by phone. It’s also referred to as an RTN, a routing transit number or an ABA routing number.

Routing Number on checks is actually a Routing Transit Number (RTN), a 9 digit code which was designed to facilitate the sorting, bundling, and shipment of paper checks back to the drawer’s (check writer’s) account. The RTN is also used by Federal Reserve Banks to process Fedwire funds transfers, and by the Automated Clearing House to process direct deposits, bill payments, and other such automated transfers. Routing numbers may differ depending on where your account was opened and the type of transaction made.
