Where to find your account number on a check
Your account number appears in the bottom right section of a check, after the routing number. On a standard check, you will see three groups of numbers printed along the bottom in magnetic ink. The first group is the routing number (nine digits), the second group is your account number (typically 10 to 12 digits), and the third is the check number (usually four digits).
The account number is the longest of the three groups and identifies your specific deposit account at your bank. It is unique to you and your account—no two people at the same bank share the same account number. When you write a check, the account number tells the bank which account to pull money from when the check is cashed or deposited.
If you look at a check and the numbers are hard to read, the account number is always printed on your bank statement and in your online banking portal. You can also call your bank's customer service line and they will read it to you over the phone.
Key Takeaways
- Your account number is the middle group of numbers at the bottom of a check, typically 10 to 12 digits long, and comes after the nine-digit routing number.
- The three number groups on a check are routing number, account number, and check number, printed left to right in that order.
- Your account number is unique to your specific account and is the same on every check you write from that account.
- If you cannot read the numbers on a physical check, your bank statement, online banking dashboard, or a call to customer service will show your account number.
The order of numbers at the bottom of a check
The bottom of a check always displays three separate number groups in the same order. Learning to spot them left to right makes it simple to find what you need without confusion.
The routing number (nine digits) comes first on the left. This number identifies which bank or credit union holds your account. The account number (10 to 12 digits) comes in the middle. The check number (usually four digits) appears last on the right and is also printed in the top right corner of the check for easy reference.
All three numbers are printed in MICR ink (Magnetic Ink Character Recognition), which is the dark, machine-readable font at the bottom. This special ink allows bank processing machines to read the numbers automatically when checks are deposited or cashed. The numbers are also printed in regular ink elsewhere on the check for you to read by eye.
Why banks print your account number on checks
Your account number on the check serves a practical purpose: it tells the receiving bank exactly which of your accounts the money should come from. When someone deposits your check, their bank scans the account number to route the payment correctly. Without it, the bank would not know which account to debit.
The account number also appears on your check register (if you keep one) and on your monthly bank statement so you can track which account each check came from. If you have multiple accounts at the same bank, each one has its own unique account number, and each checkbook is printed with the correct number for that account.
This is also why you should never share your account number with someone you do not trust. While the account number alone cannot be used to withdraw money without your signature or authorization, it is still sensitive information that identifies your account.
Finding your account number if the check is damaged or illegible
Checks can fade, get wet, or become creased over time, making the numbers hard to read. If you cannot make out your account number on a physical check, several other sources will have it.
Your bank statement (paper or online) lists your account number at the top or in the account summary section. Log into your online banking portal and look for "Account Details" or "Account Information"—your account number will be displayed there. You can also look at a deposit slip or withdrawal slip from your bank; these are printed with your account number as well.
If you do not have access to any of these, call your bank's customer service number on the back of your debit card or on your most recent statement. Have your identification ready, and they will read your account number to you. Some banks also allow you to view your account number through their mobile app.
Account number length varies by bank
Most account numbers are between 10 and 12 digits long, but the exact length depends on your bank. Some banks use 10-digit account numbers, others use 11 or 12. There is no universal standard across all U.S. banks.
The length does not affect how the number works—it is still unique to your account and functions the same way regardless of whether it has 10 or 12 digits. When you provide your account number to someone (such as for a direct deposit or automatic payment), include all the digits, even if some banks use fewer or more than others.
If you are unsure how many digits your account number has, count them on your check or look at your bank statement. The account number will always be the middle group of numbers at the bottom of the check, after the routing number and before the check number.
Using your account number for direct deposits and automatic payments
When you set up direct deposit for your paycheck or automatic bill payments, you will need to provide both your routing number and your account number. These two pieces of information together tell the sending bank exactly where to send the money.
You can find both numbers on your check, or you can get them from your bank statement or online banking portal. Some employers and billers have a form where you can write in these numbers by hand. Others have an online portal where you enter them. Always double-check that you have entered both numbers correctly before confirming, because a mistake in either number can cause the payment to go to the wrong account or fail entirely.
If you are not sure whether a request for your account number is legitimate, call your bank directly using the number on your debit card or statement. Do not call a number provided by the person asking for the information, as that could be a scam.
Frequently Asked Questions
Is my account number the same on every check I write?
Yes. Every check from the same account has the same account number printed on it. If you have multiple accounts at the same bank, each account has its own unique number, and each checkbook is printed with the correct number for that account.
Can someone use my account number to steal money from my account?
Your account number alone cannot be used to withdraw money. A thief would also need your signature, a PIN, or other authorization. However, do not share your account number with people you do not trust, as it identifies your account and could be used in combination with other information to commit fraud.
What if I write down my account number wrong when setting up direct deposit?
If you enter the account number incorrectly, the payment will either fail or go to a different account. The sending bank will usually notify you that the transaction failed. Check your entry against your check or bank statement and resubmit with the correct number.
Do I need to memorize my account number?
No. You can always look it up on your check, bank statement, or online banking portal. Most people do not memorize it. Write it down and keep it in a safe place if you need to reference it often.
Is the account number printed in the same place on every bank's checks?
Yes. All U.S. banks print the routing number, account number, and check number in the same order at the bottom of checks in MICR ink. The account number is always the middle group, after the routing number and before the check number.
