The fastest way to find your account number
Your bank account number is printed on the bottom left of every check you write — it's the middle set of numbers between the routing number and the check number. If you have checks on hand, that's the quickest place to look. The account number is usually 10 to 12 digits long, though the exact length varies by bank.
If you don't have checks or prefer not to dig through a checkbook, 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 type and balance are shown. Most banks display it in full, though some mask the last few digits for security on shared devices.
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 a representative will read it to you over the phone. Have your Social Security number and a form of ID ready, as banks verify your identity before sharing account details.

- The account number is typically 10 to 12 digits, but length varies by bank and account type.
Finding it on your bank statements
Paper statements mailed to your home address print your account number near the top, usually just below your name and address or next to your account type. If you've switched to paperless statements, log into your online banking portal and download or view your most recent statement as a PDF. The account number location is the same whether you're looking at paper or digital.
Older statements work just as well as recent ones — the account number doesn't change unless you close and reopen the account. If you've misplaced recent statements, you can request copies from your bank, though some banks charge a small fee for statements older than a certain period (often seven years).
Using your debit card or ATM card
Your debit card itself does not print your account number — the card number and account number are separate things. However, the back of your debit card has your bank's customer service phone number. Call that number, verify your identity, and a representative will provide your account number.
ATM cards work the same way. If you have an ATM-only card (no debit function), the back still carries the bank's phone number. Some ATMs also display your account number on the receipt after a transaction, though not all machines do this — it depends on your bank's settings.
What to do if you can't locate it
If you've lost access to statements, checks, and your online account, the most direct route is a phone call to your bank. Have your Social Security number, date of birth, and a government-issued ID number ready. The bank will verify your identity before sharing the account number — this is a security measure, not a barrier.
If you're locked out of your online account, use the "Forgot Password" or "Unlock Account" link on your bank's website to regain access. Most banks send a reset link to your email or phone number on file within minutes. Once you're back in, your account number is visible immediately.
Visiting a branch in person is another option if you have a local location. Bring a government-issued ID, and a teller will print your account number for you or write it down on a slip of paper. This takes about five minutes and requires no advance notice.
Account numbers for different account types
Checking and savings accounts at the same bank usually have different account numbers, even though they share the same routing number. If you have multiple accounts — a checking account, a savings account, and a money market account, for example — each one has its own unique account number. You'll need to identify which account you're looking for before you search.
When you log into your online banking, the account summary page typically lists all your accounts with their numbers. If you're calling the bank, tell the representative which account type you need the number for, and they'll confirm the right one before reading it aloud.
Joint accounts have one account number shared between all account holders. If you're a joint owner, you and the other owner(s) use the same account number for deposits, withdrawals, and transfers.
Why you need your account number and where it goes
Your account number is required for direct deposits (like paychecks or tax refunds), automatic bill payments, wire transfers, and ACH transfers between banks. When you set up a direct deposit for a refund or payment, you'll enter your routing number and account number together — they work as a pair to direct money to the correct account at the correct bank.
You may also need it to link your bank account to a third-party app or service, such as a budgeting tool or investment platform. These services use your routing and account numbers to verify that you own the account before connecting it.
It's safe to share your account number with trusted sources like your employer, the IRS, or your bank itself. However, be cautious about sharing it with unfamiliar websites or people who contact you unexpectedly — scammers sometimes pose as banks or government agencies to collect account information.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number is printed on the front of the card and is different from your account number. The account number is what's printed on checks or shown in your online banking. Both are needed for different purposes — the card number for purchases and the account number for direct deposits and transfers.
Can I find my account number on a mobile deposit receipt?
Some banks print the account number on mobile deposit receipts, but not all do. Check your most recent receipt — if the account number appears, it will be near the top or bottom. If it doesn't, use one of the other methods listed above.
What if my bank merged with another bank?
Your account number typically stays the same after a merger, though your routing number may change. Check your most recent statement or log into your online account to confirm both numbers are current. If you're unsure, call the bank and they'll provide the updated routing number and confirm your account number hasn't changed.
Do I need both the routing number and account number together?
Yes. For direct deposits, wire transfers, and ACH transfers, you need both numbers. The routing number tells the system which bank to send the money to, and the account number tells it which account within that bank. One without the other won't work.
Is it safe to text my account number to someone?
Avoid texting your account number to anyone, even if they claim to be from your bank. Banks and government agencies will not ask for your account number by text or email. If someone contacts you asking for it, hang up or delete the message and call your bank directly using the number on your debit card or statement.
