Your routing number is the nine-digit code at the bottom left of your checks

The routing number is printed on every check you write, positioned to the left of your account number. It identifies which bank or credit union holds your account. When someone sends you a direct deposit—a paycheck, tax refund, insurance payment, or government benefit—they need this number to route the money to the correct financial institution and then to your specific account.

The routing number stays the same for your account as long as you keep it at the same bank. If you switch banks, you get a new routing number. The number itself is always nine digits and appears in a specific order on your checks: routing number first (far left), then account number, then check number (far right).

Key Takeaways

  • Your routing number is the nine-digit code printed on the bottom left of your checks, before your account number.
  • You need your routing number whenever you set up direct deposit for paychecks, tax refunds, or government payments.
  • The routing number identifies your specific bank or credit union, not your individual account.
  • If you do not have checks, you can find your routing number by calling your bank, visiting their website, or logging into your online banking portal.

How to read the numbers on your check

The bottom of a check contains three separate codes in this order: routing number, account number, and check number. The routing number always comes first on the left side. It is printed in a special magnetic ink that machines can read, which is why it appears slightly raised or darker than regular printing.

The routing number is always nine digits with no letters. Your account number follows immediately after and is typically 10 to 12 digits long. The check number appears on the far right and is usually shorter. If you are unsure which is which, the routing number is always the leftmost set of nine digits.

Finding your routing number without a check

If you do not have checks or cannot locate one, your bank can provide the routing number in seconds. Call the customer service number on the back of your debit card, and they will read it to you over the phone. You can also log into your online banking account—most banks display the routing number in the account details or settings section, sometimes labeled "bank routing number" or "ABA number."

Visit your bank's website and look for a section on direct deposit, wire transfers, or account information. Many banks publish their routing number publicly on their site. If you bank at a large national chain like Chase, Bank of America, Wells Fargo, or Citibank, you can search "[bank name] routing number" online and find it within seconds. Credit unions typically have routing numbers listed on their member portal or website as well.

Why you need it for refunds and payments

When you are waiting for a tax refund, insurance refund, or government payment like a stimulus check or Social Security deposit, the paying organization needs your routing number to send the money to the correct bank. Without it, they cannot complete the direct deposit, and your payment may be delayed or sent to the wrong account.

The IRS, state tax agencies, insurance companies, and federal benefit programs all use direct deposit as the fastest payment method. If you provide the wrong routing number, the money may go to a different bank entirely, and you will have to contact the organization to correct it and resubmit. Providing the correct routing number the first time prevents delays and confusion.

Routing number versus account number

These two numbers work together but serve different purposes. Your routing number identifies your bank or credit union—it is the same for all customers at that institution. Your account number identifies your specific account within that bank. Think of the routing number as the address of the bank building and the account number as your mailbox inside that building.

When you set up direct deposit for a refund or payment, you must provide both numbers. The routing number tells the payer which bank to send the money to, and the account number tells the bank which account within that bank should receive it. If either number is wrong, the deposit will not reach you.

What to do if you cannot find your routing number

If you have tried calling your bank and checking online without success, ask to speak with a representative in person at a branch. Bring your debit card or a piece of mail from the bank showing your account number. They can print your routing number on the spot or write it down for you.

If you are waiting for a refund and need the routing number immediately, do not delay. Call your bank first thing during business hours. Most banks can provide this information within minutes. If you are setting up direct deposit for a paycheck or benefit payment, the organization you are working with can usually wait a day or two while you track down the number—but having it ready speeds up the process.

Frequently Asked Questions

Is my routing number the same as my bank's main routing number?

Usually yes, but some large banks have multiple routing numbers for different regions or branches. If you are having trouble, call your bank and tell them which branch you use. They will confirm the correct routing number for your specific account.

Can I use someone else's routing number if we bank at the same place?

Yes. The routing number identifies the bank, not the individual account. If you and a family member both bank at Chase, you both have the same routing number. Your account number is what makes the deposit go to your account instead of theirs.

What if I give the wrong routing number to the IRS or a government agency?

Contact the agency immediately and provide the correct routing number. They can usually update your information and resubmit the payment. The process takes a few extra days, but the money will reach you once the correction is made. Do not wait—call as soon as you realize the mistake.

Do I need my routing number to receive a check by mail instead of direct deposit?

No. Routing numbers are only for direct deposit and electronic transfers. If you choose to receive a refund or payment by check, you only need a mailing address. Direct deposit is faster, but a check is an option if you do not want to provide your banking information.
