Your checking account number is printed on the bottom left of your checks, in the second set of numbers after the routing number
The easiest place to find your account number is the bottom of any check you have. Look at the numbers printed along the bottom edge. You will see three separate groups of numbers. The first group (usually nine digits) is your routing number. The second group is your account number, typically between 10 and 12 digits. The third group is the check number itself.
If you do not have checks in front of you, your account number appears in several other places. Your bank statement—whether you receive it by mail or view it online—displays your full account number at the top or in a summary section. Your debit card does not show your account number, but your online banking portal will. Log in to your bank's website or mobile app, go to account details or account information, and your account number will be listed there.
Some banks print your account number on deposit slips or on correspondence they send you about your account. If you opened your account recently, check the welcome packet or the email confirmation you received—many banks include this information there.
Key Takeaways
- Your account number appears on the bottom of your checks, in the middle group of numbers between the routing number and the check number.
- Your bank statement and online banking portal both display your full account number if you need to find it without a check.
- Account numbers are typically 10 to 12 digits long, though this varies by bank.
- You will need your account number and routing number together when setting up direct deposit, wire transfers, or automatic payments.
Reading the numbers on the bottom of a check
The bottom of a check contains three distinct number sequences, and they appear in a specific order from left to right. The first nine-digit number is always your routing number—this identifies which bank or credit union holds your account. The second number sequence is your account number. The third sequence is the individual check number, which appears in the upper right corner of the check as well.
The numbers are printed in a special magnetic ink called MICR (Magnetic Ink Character Recognition), which allows bank machines to read them automatically during processing. This is why the numbers look slightly different from regular printed text—they are designed to be machine-readable as well as human-readable.
If you have multiple checking accounts at the same bank, each one has its own account number. The routing number stays the same, but the account number changes. This matters when you are setting up payments or transfers—using the wrong account number will send money to the wrong account, even if the routing number is correct.
Finding your account number online or on paper statements
Log into your bank's website or open the mobile app and navigate to your account overview or account details page. Most banks display your account number prominently in this section, sometimes with the last four digits masked for security on the main dashboard but the full number visible when you click into account settings. Some banks require you to click a "show account number" button or link for security reasons.
Paper statements print your account number in the header section, usually near your name and address. It appears on every statement your bank sends you. If you have older statements, the account number will be the same on all of them—account numbers do not change unless you close and reopen the account.
If you have a savings account at the same bank, it will have a different account number from your checking account, even though both use the same routing number. Make sure you are looking at the statement or account details for the correct account type.
What to do if you cannot locate your account number
Call your bank's customer service line—the number is on the back of your debit card or on your most recent statement. Have your identification ready. The bank will verify your identity by asking for your Social Security number, date of birth, or answers to security questions you set up when you opened the account. Once verified, they will provide your account number over the phone.
You can also visit a branch in person with a photo ID. A teller can print your account number for you or write it down. This is useful if you need the number when ready and do not have online access set up yet.
Some banks allow you to retrieve your account number through their automated phone system without speaking to a representative. Call the number on your debit card and follow the prompts for account information. The system will read your account number aloud or give you the option to have it sent to your email address on file.
Why you need both your account number and routing number
Your routing number and account number work together as a complete address for your account. The routing number tells the financial system which bank to send money to. The account number tells that bank which specific account within that bank should receive the money. Without both numbers, a transfer or direct deposit cannot reach the right place.
When you set up direct deposit for your paycheck, your employer needs both numbers. When you arrange a wire transfer, the receiving bank needs both. If you are paying a bill by bank transfer, the biller needs both. Using only one number will cause the transaction to fail or be delayed while the bank tries to figure out which account you meant.
The routing number is the same for all accounts at your bank, but your account number is unique to you. This is why you can safely share your routing number—it does not identify your specific account. Your account number, however, should be treated like sensitive financial information. Share it only with people or organizations you trust to receive payments or deposits into your account.
Account numbers for different account types at the same bank
If you have a checking account, a savings account, and a money market account all at the same bank, each one has its own account number. The routing number remains the same across all three accounts. This means when you are moving money between your own accounts at the same bank, you need to use the correct account number for the destination account, even though the routing number is identical.
Some banks allow you to link multiple accounts in their online portal, which makes it easier to see all your account numbers in one place. Others require you to navigate to each account separately. If you have trouble finding a specific account number, your bank's customer service can confirm which number belongs to which account type.
This matters most when you are setting up automatic transfers between your accounts or when you are reconciling your records. Using the wrong account number will send money to the wrong place, even within the same bank.
Frequently Asked Questions
Is my account number the same as my debit card number?
No. Your debit card number and your account number are different. Your debit card number is printed on the front of your card and is used for purchases and ATM withdrawals. Your account number is used for bank transfers, direct deposits, and bill payments. You can find your account number on your checks or in your online banking portal.
Can I use just my account number without the routing number?
No. Both numbers are required for transfers and direct deposits. The routing number identifies your bank, and the account number identifies your specific account within that bank. Without both, the transaction cannot be processed correctly.
What if I see different account numbers on different documents from my bank?
Double-check that you are looking at the same account type. If you have multiple checking accounts or a checking and savings account, each one has its own account number. If the numbers appear on documents for the same account type, contact your bank to clarify—this is unusual and may indicate an error.
Is it safe to write my account number down?
It is safer to keep your account number private, but writing it down for your own records is acceptable if you store it securely. Do not leave it in plain sight or share it with people you do not trust. Treat it similarly to how you would treat your Social Security number—necessary to share with legitimate financial institutions, but not for casual conversation.
How many digits should my account number have?
Most account numbers are between 10 and 12 digits, but this varies by bank. Some banks use shorter or longer account numbers. The exact length depends on your bank's system. If you are unsure whether you have copied your account number correctly, count the digits and compare them to what your bank shows in their online portal.
