Your account number is printed on the bottom left of your checks, in your bank's mobile app, and on statements mailed to you
The fastest place to look is the bottom of any check you have. The account number appears after the routing number and before the check number — it's usually 10 to 12 digits long. If you don't have checks handy, log into your bank's website or mobile app; your account number shows on the account overview or dashboard page, often labeled "Account Number" or "Account Details." You can also call your bank's customer service line, text your bank, or visit a branch in person and ask a teller to provide it.
Your most recent bank statement — whether you receive it by mail or email — also displays your account number at the top or in a section labeled "Account Information." Some banks print it on debit cards, though this varies by institution. If you're looking for a specific account (checking, savings, money market), make sure you're pulling the number from that particular account, since each one has its own number.
Key Takeaways
- Your account number appears on the bottom left of checks, right after the routing number.
- Logging into your bank's app or website shows your account number on the account overview page.
- Bank statements — mailed or emailed — display your account number in the account information section.
- Calling your bank's customer service line or visiting a branch will get you the number in seconds if you can't locate it yourself.
- Each account you hold (checking, savings, money market) has its own separate account number.
Finding it in your bank's app or online portal
Log into your bank's website or mobile app using your username and password. Once you're signed in, look for a section called "Account Overview," "Account Details," "My Accounts," or "Account Information" — the exact label depends on your bank. Your account number should appear prominently on that page, usually near your account type (checking or savings) and your current balance.
If you have multiple accounts with the same bank, each one will be listed separately with its own account number. Make sure you're looking at the correct account before you copy down the number. Some banks also let you nickname your accounts (like "Emergency Fund" or "Rent Account"), which can help you keep track of which number belongs to which purpose.
Reading it from a check or statement
The bottom of a check contains three numbers in order: the routing number (9 digits), your account number (usually 10 to 12 digits), and the check number (4 to 5 digits). The account number sits in the middle. If you're reading from left to right at the bottom of the check, skip the first set of numbers and grab the second set — that's your account number.
On a bank statement, your account number appears near the top in a section labeled "Account Information" or sometimes just printed as "Account #." Statements sent by mail and statements you download from your bank's website both include this information. If you receive statements by email, open the PDF and look at the first page; the account number is usually in the upper left or upper right corner.
Contacting your bank directly
Call the customer service number on the back of your debit card or on your bank's website. Have your Social Security number or other identifying information ready. A representative can give you your account number over the phone in under a minute. Some banks also let you text a number to retrieve account details, or you can use their chat feature if they offer one on their website.
If you prefer to speak to someone in person, visit any branch of your bank during business hours. A teller can look up your account number and write it down for you. Bring a photo ID. This option works well if you're already in the area or if you have other banking needs to handle at the same time.
Account numbers for different account types
If you have both a checking account and a savings account at the same bank, each one has its own account number. When you're looking up your number, make sure you're pulling from the correct account. Your checking account number won't work if you need to provide your savings account number, and vice versa.
Some banks also offer money market accounts, certificates of deposit (CDs), or other account types, each with its own number. If you're unsure which account you need the number for — for example, if you're setting up a direct deposit and need to know which account it goes to — contact your bank and tell them the purpose. They can confirm which account number you should use.
What to do if you can't find your account number
If you've looked in all the usual places and still can't locate it, the fastest solution is to call your bank. You don't need to have your account number to call; you can identify yourself with your Social Security number, date of birth, or the phone number on file. A representative will pull up your account and provide the number immediately.
If you've lost access to your online banking and don't have recent statements or checks, visiting a branch is your most reliable option. Bring a photo ID and explain that you need your account number. You'll have it in minutes. If you're locked out of your account due to a security issue, the bank will verify your identity through additional questions before providing sensitive information.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number and account number are different. Some banks print the account number on the debit card itself, but most do not. Your account number is what you use for direct deposits, wire transfers, and ACH payments. Your debit card number is for purchases and ATM withdrawals.
Can I use my account number to make purchases online?
No. Your account number is not a payment method. You need your debit card number, credit card number, or a digital wallet to make online purchases. Your account number is used for bank-to-bank transfers, direct deposits, and setting up automatic payments to bills.
What if I see multiple account numbers listed?
Each account you hold has its own number. If you see several numbers, they belong to different accounts — checking, savings, money market, or other account types. Make sure you're using the number for the specific account you need. If you're unsure which is which, your bank's app usually labels each account by type.
Do I need to memorize my account number?
No. You can look it up whenever you need it. Most people write it down or take a screenshot for reference when they're setting up direct deposits or making transfers. Keeping it in a secure place at home is fine; you don't need to carry it with you.
Will my account number change if I close and reopen an account?
Yes. If you close an account and later open a new one at the same bank, the new account will have a different account number. The old number becomes inactive and cannot be used.
