Your routing number is the first set of nine digits printed at the bottom left of your checks
The routing number appears as the leftmost group of nine digits on the bottom of any check you write. It comes before your account number and before the check number on the right. If you are looking at a physical check, start at the bottom left corner — that nine-digit code identifies which bank or credit union holds your account.
The routing number stays the same for every check from the same account. It does not change when you order new checks, and it does not vary by branch. It is tied to the financial institution itself and the region where your account was opened, not to you personally.
You need this number when you set up direct deposit for paychecks, arrange automatic bill payments, receive wire transfers, or file tax returns that expect a refund by bank deposit. Government agencies, employers, and insurance companies all ask for it when they need to send money into your account.
Key Takeaways
- The routing number is always the first nine digits at the bottom left of your checks, printed before your account number.
- Your routing number identifies your specific bank or credit union and does not change between checks or accounts at the same institution.
- You will need your routing number to receive direct deposits, tax refunds, insurance payouts, and wire transfers.
- If you do not have checks, your bank's website, customer service line, or a deposit slip will show your routing number.
- The routing number is public information — sharing it alone does not put your account at risk, but never share it with your account number together.
How to read the numbers at the bottom of a check
The bottom of a check contains three separate groups of numbers in this order: routing number, account number, check number. All three are printed in a special magnetic ink that machines can read quickly. The routing number always comes first on the left, and it is always exactly nine digits long.
The account number follows the routing number and is usually longer — often ten to twelve digits. The check number appears on the far right and is typically four or five digits. If you hold the check horizontally and read left to right along the bottom, you will encounter them in that sequence every time.
The same routing number appears on every check from your account, even if you order new checkbooks years apart. The account number and check number change with each individual check, but the routing number remains constant.
Finding your routing number without a check
If you do not have checks on hand, your bank's website is usually the fastest place to find your routing number. Log into your online banking account, look for a section labeled "Account Information," "Account Details," or "Routing and Account Numbers," and your routing number will be listed there alongside your account number.
You can also call your bank's customer service line — the number is on the back of your debit card or on your bank's website. A representative can tell you your routing number in under a minute. Some banks also print the routing number on deposit slips, savings account statements, or loan documents.
If you bank at a credit union, the same methods apply. Your credit union's website or a call to their member services line will provide your routing number. Credit unions use routing numbers just like banks do, and the process for finding yours is identical.
Why banks and government agencies ask for your routing number
Your routing number tells the sending institution exactly which bank to send money to. When you provide it along with your account number, the sender can deposit funds directly into your account without writing a check or using a wire service. This is how tax refunds reach your account when you file electronically, how employers set up direct deposit, and how insurance companies send claim payouts.
Government agencies use routing numbers to deliver stimulus payments, tax refunds, and benefit payments. The IRS, Social Security Administration, and state tax agencies all ask for your routing number when you want money deposited directly. Insurance companies use it the same way when they owe you a refund or settlement.
The routing number is also used for automatic bill payments and recurring transfers between accounts. When you set up a payment to come out of your checking account automatically each month, you are providing your routing number so the biller knows which bank to pull the money from.
The difference between routing number and account number
Your routing number identifies your bank or credit union. 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. Together, they tell a sender exactly where your money should go.
The routing number is the same for all customers of the same bank in the same region. Thousands of people may share your routing number if they bank at the same institution. Your account number, by contrast, is unique to you — no one else has that combination of digits at your bank.
This is why it is safe to share your routing number alone. Sharing it with your account number together is different — that combination can be used to set up unauthorized payments or transfers. If someone asks for both numbers, make sure you trust them and know why they need the information.
Routing numbers for different types of accounts
Your checking account has one routing number. If you also have a savings account at the same bank, it uses the same routing number — the routing number belongs to the bank, not to the individual account. Whether you are receiving a deposit into checking or savings, you provide the same routing number.
If you have accounts at multiple banks, each bank has its own routing number. A checking account at Bank A and a savings account at Bank B will have different routing numbers because they belong to different institutions. Make sure you are using the correct routing number for the specific bank where you want the money to go.
Some large banks have multiple routing numbers depending on the state where your account was opened or the type of account. If you have moved or opened your account a long time ago, double-check your bank's website or call customer service to confirm you have the correct routing number for your current account.
What to do if you cannot find your routing number
Start with your bank's website. Most banks have a dedicated page or section that lists routing numbers by state or account type. Search for "routing number" on the site or look in the customer service or account information section.
If the website does not help, call your bank's customer service number. This number is on your debit card, your bank statements, or the bank's website. Have your account number ready when you call, and a representative will provide your routing number immediately.
You can also visit a branch in person with your ID and ask a teller for your routing number. This takes longer than a phone call or website search, but it works if you prefer to handle it face-to-face. Bring your debit card or a recent statement to speed up the process.
Frequently Asked Questions
Is the routing number the same on all my checks?
Yes. Every check from your account has the same routing number printed at the bottom left. The only numbers that change from check to check are the check number on the right and sometimes the account number format, depending on your bank's printing.
Can someone steal money from my account if they only have my routing number?
Not with just the routing number alone. They would also need your account number to access your account. Sharing your routing number is generally safe — it is public information. Never share your routing number and account number together with someone you do not trust.
Do I need my routing number to receive a tax refund?
Yes, if you want your refund deposited directly into your bank account. You provide your routing number and account number on your tax return so the IRS knows which bank to send the money to. Without it, you can still receive a refund by check, but direct deposit is faster.
What if my bank has multiple routing numbers?
Some large banks use different routing numbers for different states or account types. Check your bank's website or call customer service to confirm which routing number applies to your specific account. Using the wrong one may delay your deposit.
Does my routing number change if I move to a different state?
Usually not. Your routing number is based on where your account was originally opened, not where you live now. If you move and want to confirm your routing number has not changed, check your bank's website or call customer service.
