Your account number is on your checks, your bank statement, and your online banking portal
Your bank account number is a string of digits unique to your checking or savings account. It appears in multiple places, and the fastest route depends on what you have in front of you right now. If you have a check, look at the bottom left — the account number is the second set of numbers, after the routing number. If you have a recent statement or online access, both show it clearly. You do not need to visit your bank in person.
You will need this number when you set up direct deposit for tax refunds, receive insurance payouts, or authorize electronic transfers. Having it on hand saves time when you are on the phone with a government agency or financial institution.
Key Takeaways
- Your account number appears on the bottom left of every check, after the routing number and before the check number.
- Bank statements — both paper and digital — display your full account number near the top or in the account summary section.
- Online banking portals show your account number on the dashboard or in account details without requiring a phone call.
- If you have no checks or statements, call your bank's customer service line with your ID ready, and they will read it to you in under a minute.
Reading the numbers on a check
The bottom of a check contains three separate numbers in this order: routing number, account number, check number. The routing number is nine digits and identifies your bank. The account number comes next and is typically 10 to 12 digits, though this varies by bank. The check number is the shortest and appears on the right side as well.
If you are looking at an old check, the account number is still valid even if the check itself expired. Banks do not change account numbers when you order new checks. Write down the account number from any check you have, and it will work for direct deposit and electronic transfers.
Finding it on your bank statement
Paper statements mailed to your home print the account number in the upper left or upper right corner, usually near your name and address. Digital statements you download or view online show it in the same location or in a dedicated account details section. The number appears in full, not masked or abbreviated.
If you receive statements from multiple accounts at the same bank — a checking account and a savings account, for example — each statement shows only that account's number. Make sure you are looking at the statement for the specific account you need. Statements from the past year are equally valid; the account number does not change.
Accessing it through online banking
Log into your bank's website or mobile app and navigate to your account dashboard or account details. Most banks display the account number prominently on the main page after you log in. Some require you to click an "Account Information" or "Account Details" link. The number is shown in full and can usually be copied to your clipboard with one click.
Online banking is the fastest method if you have internet access and remember your login. You do not have to wait for mail or dig through old documents. If you have forgotten your password, use the "Forgot Password" link on the login page — the bank will send a reset link to your email or phone.
Calling your bank directly
If you have no checks, statements, or online access, call the customer service number on the back of your debit card or on your bank's website. Have your Social Security number, date of birth, and a form of ID ready. The representative will verify your identity and read your account number to you over the phone. This takes less than five minutes.
Some banks also allow you to retrieve your account number through their automated phone system without speaking to a representative. When you call, listen for a menu option like "Account Information" or "Account Details." If the automated system does not offer this, press 0 or say "Representative" to speak to someone.
What to do if you cannot locate it
If you have lost access to all statements and checks, and you cannot reach your bank by phone, visit a branch in person with a photo ID. A teller can look up your account number in seconds. Bring your ID and be prepared to answer security questions about your account, such as recent transactions or your address.
If you are trying to set up direct deposit for a refund and need the account number immediately, online banking is your fastest option. If that is not available, the phone call to customer service is the next fastest route. In-person visits are reliable but require travel time.
Protecting your account number
Your account number is not a secret in the same way a password is — it appears on every check you write and on statements you may share with accountants or employers. However, do not post it on social media or send it to unknown numbers or email addresses. Legitimate banks and government agencies will never ask for your account number via unsolicited email or text.
When you provide your account number to set up direct deposit for a tax refund or insurance payout, you are giving it to a known organization through a secure channel. That is safe. If someone calls you claiming to be from the IRS or your bank and asks for your account number, hang up and call the organization directly using the number on your official documents.
Frequently Asked Questions
Is my account number the same as my routing number?
No. The routing number identifies your bank; the account number identifies your specific account at that bank. On a check, the routing number comes first (nine digits), and the account number comes second (usually 10 to 12 digits). You need both for direct deposit.
Can I use an account number from an old check?
Yes. Your account number does not change when you order new checks. A number from a check you wrote five years ago is still valid for direct deposit and electronic transfers today.
What if my bank does not show the full account number online?
Some banks mask the account number on their app for security and show only the last four digits. If this happens, call customer service or visit a branch with ID. They will provide the full number.
Do I need my account number to open online banking?
No. You set up online banking using your Social Security number, date of birth, and other identifying information. Once you log in, the account number is displayed. If you already have online access, you can find it there without calling the bank.
