Your routing number is the first (left-most) set of numbers printed along the bottom of your check. It’s always nine digits long and appears before your account number and check number on that same line.
Exactly Where to Look
Flip your check over so the front faces you. Along the very bottom, you’ll see a line of numbers printed in a special magnetic ink. This is called the MICR line, and it contains three separate numbers reading left to right:
- Routing number (first): Nine digits, starting at the far left. This identifies your bank.
- Account number (second): The middle set of digits. This identifies your specific account. Account numbers vary in length depending on your bank.
- Check number (third): The shortest number, at the far right. It matches the check number printed in the upper-right corner of the check.
On most checks, small symbols that look like vertical lines or colons separate these three groups. The routing number sits between the first pair of these symbols, making it easy to isolate visually.
How to Confirm You Have the Right Number
Count the digits. A routing number is always exactly nine digits, no exceptions. If the number you’re looking at is longer or shorter, you’ve likely grabbed the account number by mistake. Account numbers can range from eight to twelve digits or more, so length is the quickest way to tell the two apart.
The nine digits of a routing number break down into three internal components: the first four digits identify a Federal Reserve district and processing center, the next four identify your specific bank, and the final digit is a mathematical check digit used to verify the number is valid. You don’t need to memorize any of that, but knowing the structure helps if you ever need to double-check that you copied it correctly.
What the Routing Number Is Used For
Your routing number is essentially your bank’s address within the U.S. financial system. You’ll need it whenever money moves electronically to or from your account. Common situations include setting up direct deposit with an employer, paying bills online, linking external bank accounts for transfers, and filing your tax return to receive a refund by direct deposit.
One thing to watch: the routing number printed on your checks works for ACH transactions (direct deposits, automatic payments, electronic transfers between banks), but your bank may use a different routing number for domestic wire transfers. If you’re sending or receiving a wire, log in to your bank’s website or call to confirm the correct wire routing number rather than assuming it matches what’s on your check.
Finding Your Routing Number Without a Check
If you don’t have a checkbook handy, there are several other ways to find your routing number. Most banks display it prominently when you log in to online banking or open the mobile app. Look for an “account details” or “account information” link near your checking account balance.
You can also find it on your bank’s website by searching for “routing number” in the help section. Many banks list their routing numbers publicly since the number identifies the bank itself, not your personal account. If your bank operates in multiple regions, make sure you select the routing number that matches the state where you opened your account.
Calling your bank’s customer service line or visiting a branch will also get you the number quickly. A bank representative can confirm both the ACH routing number and the wire routing number if you need both.
