Where the account number sits on your check

Your account number is the second set of digits printed along the bottom of your check, positioned between the routing number on the left and the check number on the right. The bottom of a check contains three distinct groups of numbers separated by vertical lines, and knowing which group is which matters when you need to provide banking details to someone else.

The layout is always the same: routing number, then account number, then check number. The account number is typically 10 to 12 digits long, though this varies by bank. It appears in the same position on every check you have from that account, so once you locate it on one check, you know where to find it on all the others.

Key Takeaways

  • Your account number is the middle set of digits at the bottom of your check, between the routing number and check number.
  • Account numbers are usually 10 to 12 digits long and are printed in the same position on every check from your account.
  • The routing number comes first (9 digits), the account number comes second, and the check number comes last on the bottom line.
  • You need your account number when setting up direct deposit, authorizing automatic payments, or receiving wire transfer instructions from your bank.

Reading the three-number sequence at the bottom

The bottom of your check shows three separate numbers in this order: the routing number (9 digits), the account number (10 to 12 digits), and the check number (usually 4 to 5 digits). Each is separated by a vertical line or symbol that looks like a colon with extra marks. The account number is always in the middle position.

If you are looking at a check and see "123456789" on the far left, that is the routing number. The longer string of digits in the middle is your account number. The short number on the far right is the check number, which also appears in the top right corner of the check in regular print.

Some banks print the account number in a slightly different font or color to make it stand out, but not all do. The position is what matters — if it is the middle set of digits at the bottom, it is your account number.

Why banks print it this way

The routing number tells the banking system which bank holds your account. The account number tells that bank which specific account within their system is yours. Together, they form a complete address for your money. The check number is just a reference for you and your bank to track which physical check was used for a particular transaction.

This three-part system has been standard since checks became the primary way to move money between accounts. The order and position never change, which is why you can find these numbers on any check from your bank without having to ask.

What to do if the numbers are hard to read

If the numbers at the bottom of your check are faded, smudged, or printed too lightly to read clearly, you have other ways to find your account number. Your bank statement shows your account number at the top or in the account information section. Your debit card may also have your account number printed on it, though not all banks do this.

The fastest option is to log into your online banking account or mobile app — your account number is always visible in the account details or settings section. You can also call your bank's customer service line and provide your name and Social Security number to confirm your account number over the phone.

When you need to give out your account number

You will need your account number when setting up direct deposit for paychecks or government payments, when authorizing automatic bill payments, or when receiving wire transfer instructions from someone paying you. You may also need it when opening a new account at the same bank or when your bank asks you to verify your identity.

Your account number is not secret in the way a password is — it is printed on every check you write, which means anyone who receives a check from you already has it. However, you should not share it with people you do not trust, because combined with your routing number, it can be used to set up unauthorized automatic payments from your account.

Account number versus routing number

The routing number identifies your bank. The account number identifies your specific account at that bank. You need both pieces of information to complete most banking transactions, but they serve different purposes. Your routing number is the same for everyone at your bank, while your account number is unique to you.

If someone asks for your "banking information" or "account details," they typically want both numbers. If they ask specifically for your account number, they already have your routing number or do not need it. When in doubt, ask what they plan to use the information for — that will tell you whether you should provide one number or both.

Frequently Asked Questions

Is my account number the same as my debit card number?

No. Your debit card number is different from your account number. The card number is what appears on the front of your card and is used for purchases and ATM withdrawals. Your account number is printed at the bottom of your checks and is used for bank transfers and direct deposits.

Can someone use my account number to steal money?

Your account number alone is not enough to steal money, but combined with your routing number, it can be used to set up unauthorized automatic payments or ACH transfers. This is why you should not share your account number with people you do not trust, even though it appears on every check you write.

What if I cannot find my account number on my check?

Check your bank statement, which displays your account number in the account information section. You can also log into your online banking account or call your bank's customer service line to confirm your account number. Your debit card may also show it, depending on your bank.

Do I need both the routing number and account number for direct deposit?

Yes. Direct deposit requires both your routing number and account number so the employer's bank knows which bank to send the money to and which account within that bank should receive it. Both numbers appear at the bottom of your check in the same line.
