Where to find your account number right now
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 fastest way to see it. The account number is usually 10 to 12 digits long, though the exact length varies by bank.
If you don't have a check, your bank's website or mobile app will show it. Log in, go to your account details or account summary page, and look for "Account Number" listed alongside your account type and balance. Most banks display it in full, though some mask the first 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's website — and a representative will read it to you after verifying your identity. This takes a few minutes but requires no login.

Using your online banking portal
Log into your bank's website using your username and password. Once you're in, look for a section labeled "Accounts," "Account Details," "Account Information," or "My Accounts" — the exact name depends on your bank. Click on the account you need the number for if you have multiple accounts.
Your account number should appear on the main account page, usually near the top alongside your account type (checking, savings, money market) and current balance. Some banks also show it in a section labeled "Account Summary" or under a dropdown menu for each account. If you can't find it on the main page, check under "Settings" or "Account Preferences."
If your bank's website masks part of the number for security, you may see something like "****5678" — only the last four digits visible. In that case, you'll need to call the bank or check a physical check to see the full number.
Finding it on your debit card and statements
Your debit card does not print your account number on it — only your card number, which is different. The card number is the 16-digit number on the front of the card, but that's not what you need for bank transfers or direct deposits.
Your monthly bank statement, whether printed or digital, includes your account number at the top or in a header section. If you receive paper statements in the mail, look at the top right corner or the top center of the first page. If you view statements online through your bank's portal, the account number usually appears above the transaction list or in a dropdown showing which account the statement covers.
Older statements work just as well as current ones, so if you have a statement from several months ago, the account number on it is still correct.
What to do if you can't locate it
If you've checked your checks, your online account, and your statements and still can't find the number, call your bank directly. Have your Social Security number, date of birth, and the last four digits of your Social Security number or debit card ready so the representative can verify who you are. They'll provide your full account number over the phone.
Some banks also allow you to text or email customer service with this request, though phone calls are usually faster. If you're at a branch in person, you can ask a teller to write it down for you — bring your ID and debit card.
Do not search for your account number by emailing your bank from an email address they don't have on file, and do not respond to emails or texts claiming to be from your bank asking for account verification. Legitimate banks will never ask you to confirm your account number via email or unsolicited text.
Keeping your account number secure
Your account number is safe to share with people and organizations you trust — your employer for direct deposit, your landlord for rent payments, your utility company for automatic bill pay. These entities need it to deposit money into your account or withdraw payments you've authorized.
Do not share your account number with anyone who calls or emails you unsolicited, even if they claim to represent your bank, the IRS, or a government agency. Real banks and government offices will never ask you to confirm your account number this way. 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.
If you believe someone has your account number and may misuse it, contact your bank immediately. They can monitor for unauthorized activity and, if needed, close the account and open a new one with a different number.
Account number vs. routing number
Your account number and routing number are two different things, and both are needed for certain transactions. Your account number identifies your specific account at your bank — it's unique to you. Your routing number identifies your bank itself and is the same for all customers at that bank.
Both appear on the bottom of your checks in this order: routing number first (leftmost), then account number (middle), then check number (rightmost). When you set up direct deposit or authorize an automatic payment, you'll usually need to provide both numbers so the money goes to the right bank and the right account within that bank.
If you need your routing number, it's also on your checks, in your online banking portal, or available by calling your bank. Your bank's website often has a "Routing Number" lookup tool if you know your state and branch location.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16-digit number printed on the front of your debit or credit card. Your account number is different and appears on your checks or in your online banking portal. Some people have multiple cards linked to the same account, so the card number and account number are separate identifiers.
Can I see my account number on my bank's mobile app?
Yes. Open your bank's mobile app, log in, and navigate to your account details or account summary. The account number should appear there, though some apps mask part of it for security if you're on a shared device. If you can't find it in the app, the website version usually shows it more clearly.
What if my bank doesn't show the full account number online?
Call your bank's customer service line or visit a branch in person with your ID. A representative can provide the full number after verifying your identity. You can also find it on any check you've written or on a printed bank statement.
Do I need my account number to check my balance?
No. You only need your username and password to log into online banking and check your balance. Your account number is needed when you're setting up deposits or payments, not for viewing your account.
Is it safe to text my account number to someone?
Text is not secure, so avoid sending your account number via text message. If you need to provide it to someone you trust, use a phone call or meet in person. For online transactions with established companies, use their secure website or app rather than email or text.
