Where to find your account number right now
Your bank account number is printed on the bottom left of every check you write. If you have checks, look at the second set of numbers on the bottom of any check — that is your account number. The first set is your routing number; the account number comes after it.
If you do not have checks or cannot find them, log into your bank's website or mobile app. Your account number appears on the account summary page, usually near the top where your account name and balance are shown. Most banks also display it when you click "Account Details" or "Account Information."
You can also call your bank's customer service line — the number is on the back of your debit card or on your bank statements — and ask a representative to read it to you. Have your Social Security number or card number ready to verify your identity.
Key Takeaways
- Your account number is on the bottom left of any check you own, printed as the second series of numbers after your routing number.
- Log into your bank's website or app and look for "Account Details" or "Account Information" to see your account number on screen.
- Call your bank's customer service line and ask them to provide your account number after you verify your identity.
- Your account number is unique to that specific account at that specific bank — do not share it with people you do not trust.
- If you have multiple accounts at the same bank, each one has its own account number.
Finding your account number on paper statements
If you receive paper bank statements in the mail, your account number is printed at the top of every statement. Look for a line that says "Account Number" or "Acct #" followed by a series of digits — usually between 8 and 17 digits long, depending on your bank.
The statement also shows your routing number, usually near the account number. Some banks print both numbers together in a box labeled "Banking Information" or similar. If you are unsure which number is which, the routing number is always shorter — typically 9 digits — and the account number is longer.
Keep old statements in a safe place. If you lose access to your online account or cannot reach your bank by phone, a statement from the past few months will have the information you need.
Retrieving your account number from online banking
Open your bank's website or app and sign in with your username and password. Once you are logged in, look for a page labeled "Accounts," "My Accounts," or "Account Summary." This page usually displays all your accounts at that bank, along with their balances.
Click on the specific account you need the number for. A details page will open showing your account number, routing number, account type (checking or savings), and other information. Some banks require you to click a separate link or button labeled "View Account Details" or "Account Information" to see the full account number.
If you cannot find it on the main account page, look for a section called "Transfer Funds," "Wire Money," or "Payment Information" — these pages often display your account number because you need it to set up transfers. You can also search the bank's help section for "find account number" to see step-by-step instructions specific to that bank's website layout.
What to do if your bank does not show the number online
Some banks, particularly smaller regional banks or credit unions, do not display the full account number in their online banking system for security reasons. If you log in and cannot find it, call the customer service number on the back of your debit card or on a recent statement.
Have your identification ready — the bank will ask for your Social Security number, date of birth, or the last four digits of your card to confirm you are the account holder. Once verified, a representative can read your account number to you over the phone. Ask them to spell it out or repeat it so you can write it down correctly.
You can also visit a branch in person with a photo ID. A teller can print your account number for you or write it on a piece of paper. This is often the fastest option if you need it immediately.
Understanding account numbers across different banks
Each bank assigns account numbers independently, so the same person can have different account numbers at different banks. If you have a checking account and a savings account at the same bank, each one has its own account number. If you have accounts at two different banks, those numbers are completely separate.
Account numbers are not standardized in length — some banks use 8-digit numbers, others use 12 or 17. The length does not matter; what matters is that the number is correct for the specific account and bank you are using it for.
Your account number stays the same for as long as you keep that account open. If you close an account and open a new one at the same bank, you will receive a new account number. The old number cannot be reused for a certain period, so do not try to use an old account number if you have closed that account.
Keeping your account number safe
Your account number is sensitive information. Do not share it with anyone unless you are setting up a direct deposit, wire transfer, or other legitimate transaction. Scammers can use your account number along with your routing number to attempt unauthorized withdrawals or transfers.
When you provide your account number to set up direct deposit (for paychecks or refunds) or automatic payments, make sure you are giving it to a trusted organization — your employer, the government agency sending a refund, or a company you have an established relationship with.
If you suspect someone has your account number and may use it fraudulently, contact your bank immediately. They can monitor your account for suspicious activity and issue you a new account number if necessary, though this usually requires closing the old account and opening a new one.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies your bank; your account number identifies your specific account at that bank. On a check, the routing number is the first set of numbers on the bottom, and the account number is the second set. Both are needed to set up direct deposit or wire transfers.
Can I use my debit card number instead of my account number?
No. Your debit card number is different from your account number. Some transactions require your account number specifically — direct deposit, wire transfers, and ACH payments. Your debit card number is for card purchases and ATM withdrawals.
What if I have multiple accounts at the same bank?
Each account has its own account number. When you log into online banking, you will see all your accounts listed separately, each with its own number. Make sure you use the correct account number for the transaction you are setting up.
Do I need my account number to check my balance?
No. You can check your balance by logging into online banking or calling your bank's automated phone line using just your debit card number or username. You only need your account number when setting up transfers, direct deposits, or wire payments.
What should I do if I think someone has my account number?
Call your bank immediately and tell them you believe your account number has been compromised. They will review your account for unauthorized activity and can issue you a new account number if needed. Monitor your account closely for the next few weeks for any transactions you did not authorize.
