The fastest way: check your checks or online banking

Your bank account number appears on the bottom left of every check you write, printed after the routing number. If you have a checkbook in front of you, open it and look at the first check — the account number is the second set of digits on the bottom line, usually 10 to 12 digits long.

If you do not have checks or prefer not to dig them out, log into your bank's website or mobile app. Your account number is almost always visible on the main dashboard or account summary page, sometimes labeled "Account Number" or "Account ID". Most banks show it in full; some mask it with asterisks for security and require you to click to reveal the complete number.

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 for your account number. Have your ID ready. A representative will confirm your identity and read it to you.

Key Takeaways

  • Your account number is printed on the bottom left of your checks, after the routing number.
  • Log into your bank's website or app to see your account number on the account summary or dashboard.
  • Call your bank's customer service line and ask; they will confirm your identity before providing it.
  • Bank statements mailed to your address also display your account number, usually near the top.
  • Never share your account number with anyone who contacts you unsolicited, even if they claim to be from your bank.

Finding it on paper statements

If you receive paper statements in the mail, your account number is printed on every one. Look near the top of the statement, usually in the upper right corner or in a section labeled "Account Information". The statement date and account number are typically grouped together for easy reference.

Older statements work just as well as recent ones — your account number does not change unless you close the account and open a new one. If you have kept statements from the past year, any of them will show the number you need.

When you cannot access your account online

If you have forgotten your online banking password or cannot log in for another reason, do not try to reset it just to find your account number. Call your bank instead. This is faster and avoids the risk of locking yourself out of your account.

Have your Social Security number, date of birth, and a form of ID ready when you call. The bank will verify your identity through these details before reading your account number to you over the phone. Write it down as they say it to make sure you have it correct.

Account numbers for different account types

If you have multiple accounts at the same bank — a checking account, a savings account, and a money market account, for example — each one has its own account number. When you log into online banking, you will see all your accounts listed separately, each with its own number.

When you need to provide an account number for a transaction, make sure you are giving the number for the correct account. If you are setting up a direct deposit to your checking account, for instance, use the checking account number, not your savings account number. The routing number stays the same across all your accounts at that bank, but the account numbers are different.

What to do if you cannot find it anywhere

If you have no checks, cannot log into online banking, and do not have recent statements, your bank can still provide the number. Visit a branch in person with your ID, or call the customer service number on the back of your debit card. Both options require identity verification but take only a few minutes.

If you have closed your account or switched banks and need the account number from an old account, contact that bank directly. They keep records of closed accounts and can provide the number if you can verify your identity. This is useful if you are tracking down an old refund or payment that was sent to that account.

Keeping your account number secure

Your account number is not as sensitive as your PIN or online banking password, but it is still private information. Do not share it with anyone who calls or emails you unsolicited. Legitimate businesses and government agencies will never ask for your account number over the phone unless you initiated the contact.

When you provide your account number for a legitimate transaction — setting up direct deposit, paying a bill, or receiving a refund — make sure you are dealing with the actual company or agency. Verify the phone number or website independently rather than using contact information from an email or text message.

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 the bank uses internally to identify your account; the card number is tied to that account but is not the same thing. You need the account number for direct deposits and bank transfers, not the card number.

Can I find my account number on a bank statement if I only have an online version?

Yes. Downloaded or printed PDF statements show your account number in the same place as paper statements — usually near the top in an account information section. If you receive statements by email, open the PDF and look for the account number there.

What if my bank uses a different name for the account number?

Some banks label it "Account ID" or "Customer Account Number" instead of "Account Number". The position and length are usually the same — a 10 to 12 digit number on checks or in your online account summary. If you are unsure which number is your account number, call the bank and ask them to confirm.

Do I need my account number to check my balance?

No. You can check your balance by logging into online banking with your username and password, calling your bank's automated line, or visiting an ATM with your debit card. You only need the account number when you are setting up a transaction that requires it, like a direct deposit or wire transfer.
