Your routing number is a nine-digit code that tells the banking system which bank holds your account

Every bank in the United States has a routing number, also called a routing transit number or ABA number. When you send money from your checking account to someone else—through a wire transfer, ACH payment, or direct deposit setup—that nine-digit code tells the receiving bank's computer system exactly which financial institution to pull the money from. Without it, the payment has no address.

The routing number is not secret and not unique to you. Everyone who banks at the same branch of the same bank shares the same routing number. It is printed on the bottom left of your paper checks, and you can find it online through your bank's website or by calling customer service.

You will need your routing number whenever you set up a payment that moves money out of your account—payroll direct deposit, bill pay through your employer, wire transfers, or ACH transfers to another person or business. You will also need it if someone else is sending money to you and asks for your bank details.

Key Takeaways

  • Your routing number is a nine-digit code printed on the bottom left of your checks, specific to your bank and branch but shared by all customers at that location.
  • The routing number tells the banking system which bank to pull money from when you set up a payment or direct deposit.
  • You can find your routing number on your checks, through your bank's website, by calling customer service, or through the Federal Reserve's routing number search tool.
  • Your routing number is different from your account number; you need both to complete most banking transactions.
  • Sharing your routing number is safe—it is public information and cannot be used to withdraw money without your account number.

Where to find your routing number on a check

If you have a checkbook, your routing number is printed at the bottom of every check in the leftmost position. It is always nine digits long and appears before your account number. The format looks like this: the routing number comes first, then your account number, then the check number on the far right.

The routing number is printed in a special magnetic ink that allows bank sorting machines to read it automatically. You can read it by eye just as easily—look at the bottom left corner of any check and you will see the nine digits clearly.

Finding your routing number online or by phone

If you do not have checks or cannot locate them, your bank's website has your routing number listed in the account details section. Log into your online banking portal, look for "account information," "routing number," or "bank details," and it will be displayed there. Most banks also list routing numbers on their main website under a "customer service" or "banking information" page.

You can also call your bank's customer service number—usually printed on the back of your debit card—and ask for your routing number. A representative will provide it immediately. If you do not know your bank's phone number, search online for "[Your Bank Name] customer service" and you will find the number.

The Federal Reserve also maintains a public routing number search tool at frbservices.org. Enter your bank name and state, and the system will return the routing number for that location. This tool is useful if you are switching banks or need to verify that a routing number you have is correct.

Routing number versus account number

Your routing number and account number are two separate pieces of information, and both are needed for most transactions. The routing number identifies your bank; the account number identifies your specific account within that bank. Think of it like an address: the routing number is the city and state, and the account number is the street address and house number.

On a check, the routing number appears first (nine digits on the left), followed by your account number (usually ten to twelve digits). When you set up direct deposit or a wire transfer, you will be asked for both. Providing only one without the other will cause the transaction to fail.

Is it safe to share your routing number

Yes. Your routing number is public information and cannot be used to withdraw money from your account. Someone who knows only your routing number cannot access your funds, make charges, or open new accounts in your name. They would also need your account number, and even with both pieces of information, most transactions require additional verification like a signature or PIN.

You share your routing number every time you set up direct deposit with an employer, provide banking details to a vendor, or give someone your checking account information to send you a payment. Banks expect this information to be shared and have built security around the account number and verification steps instead.

That said, you should never share your full banking information—routing number plus account number—with someone you do not trust. While the routing number alone is safe, the combination of both numbers plus your name is enough to set up certain types of transfers. Only provide complete banking details to employers, government agencies, and businesses you recognize and trust.

What happens if you use the wrong routing number

If you provide an incorrect routing number when setting up a payment or direct deposit, the transaction will either fail or be sent to the wrong bank. Most modern banking systems catch the error before the money moves and return it to you with a message that the routing number is invalid.

If the money does reach the wrong bank, it typically gets returned to your account within one to three business days. The sending bank's system will flag the mismatch and reverse the transaction. You may see a temporary hold on your account during this time, but the funds will come back.

To avoid this problem, double-check your routing number before you submit any payment or direct deposit form. Verify it against your checks, your bank's website, or a call to customer service. Taking thirty seconds to confirm prevents delays and confusion.

Routing numbers for different types of transfers

Most banks use the same routing number for all transaction types—direct deposit, ACH transfers, wire transfers, and bill pay. However, some large banks maintain separate routing numbers for wire transfers versus ACH transfers. If your bank is one of these, you will see both numbers listed on your account information page or when you call customer service.

When you set up a transaction, the form will usually specify which type of routing number you need. If it asks for a "wire routing number," use the wire-specific number. If it asks for an "ACH routing number" or just "routing number," use the standard one. Your bank's website will clearly label which is which if your bank has more than one.

If you are unsure which routing number to use, call your bank or check the instructions on the form you are filling out. Most forms include a note explaining where to find the correct routing number for that specific transaction type.

Frequently Asked Questions

Can someone withdraw money from my account if they have my routing number?

No. A routing number alone cannot be used to withdraw money. Someone would need both your routing number and your account number, plus additional verification like a signature or PIN. Even with all that information, most banks require extra steps before releasing funds. Your routing number is safe to share.

Do all banks in the same city have the same routing number?

No. Each bank has its own routing number, and large banks with multiple branches may have different routing numbers for different regions. A Chase branch in New York has a different routing number than a Chase branch in California. Your checks or online account information will show the correct routing number for your specific branch.

What if I set up direct deposit with the wrong routing number?

Your employer's payroll system will reject the deposit and return it to the payroll account. You will not receive your paycheck on the scheduled date. Contact your HR or payroll department immediately, provide the correct routing number and account number, and ask them to resubmit the deposit. Most employers can process the corrected deposit within one to two business days.

Is the routing number the same for checking and savings accounts at the same bank?

Yes. Both your checking and savings accounts at the same bank use the same routing number. The routing number identifies the bank; your account number identifies which specific account within that bank. When you set up a transfer between your checking and savings, you use the same routing number for both.

Where do I find the routing number if my bank is online-only?

Online banks display routing numbers in your account information section, just like traditional banks. Log into your account, look for "account details" or "bank information," and the routing number will be listed there. You can also call the bank's customer service line or check their website's FAQ section. Online banks are required to provide this information to customers.
