Your account number is printed at the bottom of your check, in the middle section between two sets of numbers
The bottom of a check contains three separate groups of numbers, each serving a different purpose. Reading from left to right, you'll see the routing number first (nine digits), then your account number (typically 10 to 12 digits, though this varies by bank), and finally the check number on the right. The account number is the longest group in the middle.
Your account number identifies which specific account at your bank the check is drawn from. If you have multiple accounts at the same bank—a checking account and a savings account, for example—each one has its own account number. The routing number tells the receiving bank which bank to send the money to; the account number tells that bank which account within your bank to deposit it into.
The numbers are printed in a special magnetic ink called MICR (Magnetic Ink Character Recognition) so that check-processing machines can read them automatically. This is why the font looks different from the printed text elsewhere on the check.
Key Takeaways
- Your account number appears at the bottom center of the check, between the routing number on the left and the check number on the right.
- Account numbers are typically 10 to 12 digits long, though the exact length depends on your bank.
- The account number identifies your specific account; the routing number identifies your bank.
- If you have multiple accounts at the same bank, each account has a different account number but shares the same routing number.
How to read the numbers in order
Start at the bottom left of the check. The first nine digits you encounter are your routing number. After a small space, the next group of digits—usually longer—is your account number. At the far right, you'll see a shorter number, which is the check number (this also appears in the top right corner of the check for easy reference).
Some checks print these numbers more clearly than others. If the numbers are hard to read because of fading, damage, or poor printing quality, you can find your account number through other means: your bank statement, your online banking portal, or by calling your bank's customer service line.
Why you might need your account number
You'll need your account number when setting up direct deposit for paychecks or government payments, arranging automatic bill payments, or providing banking information to a third party who needs to send you money. Insurance companies, employers, and government agencies often request both your routing number and account number together to process refunds or payments electronically.
When you provide this information, you're giving someone the details they need to deposit money directly into your account without using a check. This is faster and more reliable than waiting for a paper check to arrive and then depositing it yourself.
What if the numbers are unclear or damaged
If your checks are old, worn, or printed poorly, the numbers at the bottom may be faded or hard to read. In this case, don't guess—contact your bank directly. You can call the customer service number on the back of your debit card or log into your online banking account, where your account number is always displayed clearly.
If you've ordered new checks and they haven't arrived yet, your bank can provide your account number over the phone or through your online portal. You don't need a physical check in front of you to access this information.
The difference between account number and check number
These two numbers serve different purposes and appear in different locations on the check. Your account number is at the bottom center and identifies your account. Your check number appears both at the bottom right (in MICR format) and in the top right corner (in regular print) and identifies that specific check within your account.
When you write a check, the check number helps you and your bank track which specific check you wrote. The account number ensures the money comes from the right account. If you write multiple checks from the same account on the same day, each check has a different check number, but they all share the same account number.
Finding your account number without a check
You don't need a physical check to find your account number. Log into your online banking account—most banks display it prominently on the dashboard or account summary page. You can also find it on your monthly bank statement, usually near the top. If you have a debit card, call the customer service number on the back and ask; the representative can read it to you over the phone.
Some banks print your account number on statements but not on debit cards for security reasons. If you're having trouble locating it, visiting your bank in person or calling during business hours is the fastest way to get the information you need.
Frequently Asked Questions
Is my account number the same on all my checks?
Yes. Every check from the same account has the same account number printed at the bottom. If you order new checks, they will have the same account number as your old checks. The only number that changes is the check number, which increments with each new check.
Can someone use my account number to steal money from my account?
Your account number alone is not enough to withdraw money. A thief would also need your routing number and typically additional verification like a PIN or signature. However, you should still treat your account number as sensitive information and not share it with people you don't trust. Only provide it to employers, government agencies, and financial institutions you've contacted directly.
What if I can't find the account number on my check?
Check the bottom center of the check again—it's the longest group of numbers between the routing number and check number. If it's still unclear, contact your bank by phone or through your online account portal. They can provide your account number immediately without requiring a check.
Do I need both the routing number and account number to receive a payment?
Yes. Most organizations that send money electronically—employers, insurance companies, government agencies—require both numbers. The routing number directs the payment to your bank; the account number directs it to your specific account within that bank. One without the other won't work.
