How to Find Your Bank Routing Number (ABA Number Explained)

Your bank’s routing number is one of the most important pieces of information you’ll use when moving money. It ensures that funds go to the right bank, whether you’re setting up direct deposit, paying bills, or wiring money.

What Is a Routing Number?

A routing number is a 9-digit code that identifies your bank in the U.S. financial system. It is issued by the American Bankers Association (ABA), which is why you might also hear it called an ABA number. Both terms mean the same thing.

Which Is the Routing Number?

When you look at the bottom of a paper check, you’ll see three sets of numbers:

• Routing Number – The first 9-digit number on the bottom left.
• Account Number – The second set of digits, unique to your account.
• Check Number – The last set of digits, usually matching the number at the top right of the check.

Focus on that first set of digits — that’s your routing number.

What the Digits Mean

Each routing number is structured to direct payments accurately:

• Digits 1-4: Show the Federal Reserve district and processing center.
• Digits 5-8: Identify your specific bank or credit union.
• Digit 9: Acts as a check digit to confirm the number is valid.

This design helps prevent errors and keeps money flowing to the right place.

Why You Might Need It

You may be asked for your routing number when:

• Setting up direct deposit
• Making automatic bill payments
• Sending or receiving wire transfers
• Linking to payment apps like PayPal or Venmo
• Requesting tax refunds directly to your bank account
