Check your checks or debit card first
Your bank account number is printed on the bottom left of every check you have. Look at the string of numbers on the bottom of the check — the first set (usually 9 digits) is your routing number, and the second set is your account number. The account number is typically 10 to 12 digits long, though this varies by bank.
If you do not have checks handy, your debit card statement or the back of your debit card itself may also show the last few digits of your account number, though usually not the full number for security reasons. Your bank statement — whether you receive it by mail or view it online — will always display your complete account number at the top or in the account details section.
Key Takeaways
- Your account number appears on the bottom of every check you write, printed as the second set of numbers after your routing number.
- Online banking portals show your full account number in the account summary or details section, accessible 24/7 from any device.
- Calling your bank's customer service line is the fastest way to get your account number if you have no checks or online access.
- Your bank may require you to verify your identity with personal information before revealing your account number over the phone.
- Mobile banking apps typically display your account number in the account information or settings menu.
Log into your online banking account
Most banks let you view your account number by signing into their website or mobile app. Once you are logged in, look for a section labeled "Account Details," "Account Information," or "My Accounts." Your full account number will be displayed there, usually near your account type (checking or savings) and current balance.
If you have never set up online banking, you can register on your bank's website using your debit card number, Social Security number, and other identifying information. The registration process typically takes a few minutes, and you will have immediate access to your account information once it is complete.
Call your bank's customer service line
Every bank publishes a customer service phone number on its website, on your statements, and on the back of your debit card. When you call, have your Social Security number, date of birth, and the last four digits of your debit card ready. The representative will verify your identity before providing your account number.
Customer service lines are usually open during business hours, Monday through Friday, and many banks now offer 24/7 phone support. Wait times vary depending on the time of day and how busy the bank is, but you should expect to reach someone within 5 to 15 minutes during peak hours.
Visit your bank branch in person
Walk into any branch of your bank with a photo ID and ask a teller for your account number. This is the most straightforward method if you prefer face-to-face interaction or if you do not have online access. The teller can print out a statement showing your account number or write it down for you on the spot.
Bring your ID and debit card to speed up the process. If you do not have either, the teller may ask for additional information to confirm your identity, such as your Social Security number or answers to security questions you set up when you opened the account.
Check your bank statements
Paper statements mailed to your home display your account number prominently, usually in the top section under your name and address. If you have switched to paperless statements, log into your online banking portal and download a recent statement as a PDF — your account number will appear in the same location.
Statements typically arrive monthly, but you do not have to wait for the next one. Most banks let you view and download statements from the past 12 to 24 months through their online portal, so you can retrieve your account number immediately without waiting for mail delivery.
Use your bank's mobile app
If you have downloaded your bank's official mobile app, open it and navigate to the account information or settings section. The app will display your account number alongside your account type and balance. Some banks show the full number, while others display only the last four digits for security — if you see only partial digits, use one of the other methods above to get the complete number.
Make sure you are using your bank's official app, not a third-party financial app. Download directly from the Apple App Store or Google Play Store, or visit your bank's website and click the link to their official app to avoid downloading a fraudulent version.
Frequently Asked Questions
Is my account number the same as my routing number?
No. Your routing number identifies which bank you use (usually nine digits), while your account number identifies your specific account at that bank (typically 10 to 12 digits). Both appear on the bottom of your checks, with the routing number first and the account number second.
Can I see my full account number on my debit card?
Most debit cards show only the last four digits of your account number for security reasons. To see your full account number, check a paper check, log into online banking, call customer service, or visit a branch in person.
What if I do not have checks or online banking set up?
Call your bank's customer service line with your Social Security number and date of birth ready. A representative will verify your identity and provide your account number. You can also visit a branch with a photo ID and ask a teller to provide it.
Is it safe to share my account number?
Your account number alone cannot be used to withdraw money or open new accounts without additional information like your routing number and personal details. However, only share it with trusted sources like your employer for direct deposit, your bank, or verified financial institutions you are doing business with.
How long does it take to get my account number if I call the bank?
Once you reach a customer service representative and verify your identity, you will receive your account number within one to two minutes. The wait to reach a representative varies from 5 to 15 minutes depending on call volume and time of day.
