Your bank account number is printed on the bottom left of your checks, shown in your online banking portal, and available by calling your bank's customer service line.
If you have checks, look at the bottom of any check. You will see three sets of numbers separated by colons or vertical lines. The middle set is your routing number. The last set, which is usually 10 to 12 digits long, is your account number. This is the fastest way to find it if you have a check in front of you right now.
If you do not have checks or prefer not to use them, log into your bank's website or mobile app. Most banks display your account number prominently on the dashboard or account summary page. Some banks require you to click into a specific account to see the full number — they may show only the last four digits on the main screen for security.
You can also call your bank's customer service number, which is on the back of your debit card or on your bank statements. Have your identification ready. A representative will confirm your identity and read your account number to you over the phone.
Key Takeaways
- Your account number appears on the bottom left of any check you have, as the last set of numbers after the routing number.
- Log into your bank's website or app to view your account number on your account summary or dashboard page.
- Call your bank's customer service line and ask for your account number — they will verify your identity first.
- Your account number is different from your routing number; you need both for wire transfers and direct deposits.
- Never share your full account number with anyone except your employer, your bank, or a business you are sending money to intentionally.
Finding your account number online
Most banks make this straightforward. Open your bank's website or app, sign in with your username and password, and look for a section labeled "Account Summary," "Account Details," or "My Accounts." Your account number will be listed there, usually near the account type and balance.
Some banks hide the full number by default and show only the last four digits (for example, ****5678). If you see this, look for a button or link that says "Show Full Account Number" or "View Full Details." You may need to enter your password again or answer a security question before the full number displays.
If you cannot find it in your account summary, check your recent bank statements. Statements sent by mail or email usually print your account number at the top or in a header section. This is reliable because statements are official bank documents.
Reading your account number from a check
Look at the bottom of any check. You will see a series of numbers printed in a special magnetic ink font. These numbers are arranged in groups, usually separated by colons or vertical lines.
The first group on the left is your routing number (nine digits). The middle group is your account number (typically 10 to 12 digits). The last group on the right is the check number. Your account number is the one you need for direct deposits, wire transfers, and setting up automatic payments.
If the numbers are hard to read because the check is old or worn, order new checks from your bank or a check printing service. Your bank can also confirm the number by phone or through your online portal.
Getting your account number by phone
Call the customer service number on the back of your debit card, on your bank statements, or on your bank's website. Have your Social Security number, date of birth, and a form of identification ready.
When you reach a representative, explain that you need your account number. They will ask security questions to confirm you are the account holder. Once verified, they will read your account number to you. Write it down or ask them to repeat it so you have it correct.
This method works even if you do not have online access or checks. It is also useful if you need to verify that the number you found elsewhere is correct.
Account number versus routing number
These are two different numbers, and you need both for many transactions. Your routing number identifies which bank or credit union you use. Your account number identifies your specific account within that bank.
Think of it this way: the routing number is like your bank's address, and the account number is like your apartment number inside that building. When you set up direct deposit with your employer, you provide both numbers so the money goes to the right bank and the right account.
You can find both numbers on the bottom of a check, in your online banking portal, or by calling your bank. Some banks print them on statements as well.
What to do if you cannot find your account number
If you have tried checking your checks, your online portal, and your statements and still cannot locate it, call your bank. This is the most reliable option. Customer service representatives have access to your account and can provide the number immediately.
Have your identification and account information ready before you call. If you do not remember your username or password for online banking, ask the representative to help you reset it during the same call. Once you regain access, you can view your account number anytime in the future.
If you are trying to set up direct deposit or make a payment and need the number urgently, calling is faster than waiting for a new statement or ordering checks.
Keeping your account number safe
Your account number is sensitive information. Do not share it with anyone except your employer (for direct deposit), your bank, or a business you are intentionally sending money to. Scammers sometimes call or email pretending to be from your bank and ask for your account number — legitimate banks never do this.
When you provide your account number online, make sure you are on your bank's official website, not a phishing site. Check the URL in your browser's address bar to confirm it matches your bank's real web address.
If you suspect someone has your account number without permission, contact your bank immediately. They can monitor your account for unauthorized activity and issue you a new account number if necessary.
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 your card and is different from your account number. Your account number is on the bottom of your checks or in your online banking portal. They are separate numbers that serve different purposes.
Can I find my account number on my debit card?
No, your debit card does not display your account number. The number on your card is your card number, which is used for purchases and ATM withdrawals. To find your account number, check a check, log into online banking, or call your bank.
What if I have multiple accounts at the same bank?
Each account has its own account number. If you have a checking account and a savings account, they will have different account numbers. When you log into online banking, you can see all your accounts listed separately, each with its own number. Make sure you use the correct account number for the transaction you are making.
Do I need my account number to use an ATM?
No. You only need your debit card and PIN to use an ATM. Your account number is needed for direct deposits, wire transfers, setting up automatic payments, and other banking transactions where you need to identify a specific account.
Can I change my account number?
You cannot change your existing account number, but you can open a new account with a new number if you want. Most people keep the same account number for years. If you are concerned about security, contact your bank to discuss your options.
