The fastest way: look at the bottom left of your checks
Your checking account number appears on every check you write, printed at the bottom left in the second set of numbers. The format is usually three groups: the routing number (first), your account number (second), and the check number (third). If you have checks in front of you right now, that's the quickest place to look.
Not all banks print checks the same way, so the position can vary slightly, but the account number is always one of those three number groups at the bottom. It's typically 10 to 12 digits long, though this varies by bank.
Key Takeaways
- Your account number is printed on the bottom left of your checks, in the second group of numbers after the routing number.
- Your bank's website or mobile app will display your account number in the account details or settings section.
- You can call your bank's customer service line or visit a branch in person to ask for your account number.
- Your monthly bank statement lists your account number on the first page, usually near the top.
- Debit cards do not print the account number on the card itself, so you'll need to use one of the other methods.
Log into your online banking account or mobile app
Most banks display your account number prominently once you log in. Look for a section labeled "Account Details," "Account Information," or "My Accounts." The account number is usually shown in full or with the last four digits visible and the rest masked for security.
If you can't find it in the main dashboard, check the settings or profile section. Some banks hide it one level deeper. The mobile app often shows it in the same place as the website version.
Check your monthly bank statement
Your account number appears on every statement your bank sends you, whether by mail or email. It's typically printed near the top of the first page, often next to your name and address. If you receive paper statements, look at the upper right or left corner. Digital statements usually show it in the same location.
If you've deleted old emails, you can request a copy from your bank or log into your online account to view past statements. Most banks keep at least 12 months of statements available online.
Call your bank or visit a branch
Your bank's customer service team can tell you your account number over the phone. Have your ID ready—they'll ask you to verify your identity before sharing it. You can find the customer service number on your debit card, on your bank's website, or on a recent statement.
If you prefer to ask in person, any branch can print or write down your account number for you. Bring a photo ID. This takes a few minutes and requires no advance notice.
Look at your debit card paperwork
When your bank issued your debit card, they sent welcome materials that often included your account number. Check any letters or documents that came with the card. The account number may be listed on the welcome letter or on a separate sheet with your account details.
If you've thrown away the original materials, don't worry—the other methods above will get you the number faster anyway.
What your account number is used for
You need your account number when you set up direct deposit, arrange automatic bill payments, or receive a wire transfer. Employers ask for it to deposit your paycheck. Utilities and subscription services ask for it to pull payments from your account. Anyone sending you money via bank transfer will need it.
Your account number is not the same as your routing number. The routing number identifies your bank; the account number identifies your specific account at that bank. Together, they form the complete address for your account.
Frequently Asked Questions
Is it safe to give out my account number?
Your account number alone cannot be used to withdraw money from your account—a thief would also need your routing number and access to your bank's systems. It's safe to share your account number with your employer, your bank, or trusted businesses you're paying. Never share it with someone who calls you claiming to be from your bank or the government.
What if I can't find my account number anywhere?
Call your bank's customer service line or visit a branch. They can confirm your identity and provide it immediately. This is the most direct route if you've lost your checks and don't have online access set up yet.
Does my debit card have my account number printed on it?
No. Your debit card shows your card number (which is different from your account number), expiration date, and name. The account number is not printed on the card itself. You'll need to use your checks, statement, or online banking to find it.
Can I change my account number?
Most banks do not allow you to change your account number. If you're concerned about fraud or privacy, contact your bank to discuss your options. In rare cases, they may close the account and open a new one with a different number, but this is not routine.
What's the difference between my account number and my routing number?
Your routing number identifies your specific bank branch (or the bank itself for large institutions). Your account number identifies your account within that bank. Both appear on your checks in the same order: routing number first, then account number. You need both to set up direct deposit or receive wire transfers.
