Your account number is the long string of digits printed on the front or back of your debit or credit card, usually between 13 and 19 digits long
The account number identifies your specific bank account or credit line to the financial institution that issued the card. When you make a purchase, transfer money, or set up automatic payments, this number tells the merchant or payment processor which account to charge. It is different from your routing number — the routing number identifies your bank, while the account number identifies you within that bank.
Most cards print the account number on the front, below the cardholder's name. Some cards, particularly older ones or certain credit cards, print it on the back. The number may be embossed (raised) or printed flat. If you cannot find it on the physical card, you can also locate it on your bank statement, in your online banking portal, or by calling your bank's customer service line.
Key Takeaways
- Your account number is the 13- to 19-digit number on your card that identifies your specific account to your bank or credit card company.
- The account number is printed on the front of most debit cards and the back of many credit cards, though location varies by issuer.
- You need your account number to set up direct deposits, automatic bill payments, wire transfers, and online purchases.
- Your account number is not the same as your routing number; the routing number identifies your bank, while the account number identifies your account within that bank.
- If your card is lost or stolen, contact your bank immediately to freeze the account; a new card will have a different account number.
Where account numbers appear on different card types
Debit cards typically print the account number on the front, below or next to the cardholder's name. The number is usually embossed so it can be read by older card readers, though many newer cards print it flat. Credit cards more often place the account number on the back, near the signature strip or security code, though some print it on the front as well.
The exact placement depends on the card issuer. If you have multiple cards from the same bank — a debit card and a credit card, for example — they will have different account numbers because they connect to different accounts. A replacement card issued after yours is lost or damaged will also have a different account number, even though it connects to the same underlying account at the bank.
When you need to provide your account number
You provide your account number when you set up automatic bill payments, such as for utilities, insurance, or loan payments. You also need it to arrange direct deposit of paychecks or government payments like tax refunds or Social Security. Wire transfers, both sending and receiving money, require your account number along with your routing number.
Online purchases do not require your account number if you are using the card itself — the merchant reads the number from the card. However, if you are paying by bank transfer or ACH (Automated Clearing House) rather than card, you will need to provide both your account number and routing number. Some merchants also ask for your account number when you call to place an order by phone.
How account numbers differ from routing numbers
Your routing number identifies the bank or credit union itself — it is the same for all customers of that institution. Your account number identifies your specific account within that bank. Together, they form a complete address for your money: the routing number says "go to this bank," and the account number says "put it in this account."
A routing number is nine digits; an account number is typically 10 to 12 digits for bank accounts, though credit card account numbers can be longer. You can find your routing number on the bottom left of a check, in your online banking portal, or by calling your bank. Your account number appears on checks as well, usually to the right of the routing number.
What to do if your card is lost or stolen
Contact your bank or credit card company immediately by phone. Most institutions have a 24-hour fraud line number on the back of your card or on your statement. Report the card lost or stolen, and the bank will freeze that account number to prevent unauthorized use. Transactions made after you report the card are typically not your responsibility.
Your bank will issue a replacement card with a new account number. This can take 7 to 10 business days for standard delivery. If you have automatic payments or direct deposits set up using the old account number, you will need to update them with the new number once the replacement card arrives. Some banks allow you to update these online; others require a phone call or a visit to a branch.
Finding your account number if you do not have the card
Log into your online banking portal or mobile app — your account number is usually displayed on the account overview page or in account settings. Check a recent bank statement; the account number appears at the top or in the account information section. You can also call your bank's customer service number, which is on your statement or online, and a representative can read it to you after you verify your identity.
If you have checks from your account, the account number is printed on the bottom center of each check, between the routing number on the left and the check number on the right. Some banks also print it in the upper right corner. If none of these options are available to you, visit a branch in person with a photo ID and ask a teller to provide your account number.
Keeping your account number secure
Treat your account number like you would your Social Security number — do not share it with people you do not trust, and do not write it down in places where others can see it. When you provide it over the phone, make sure you initiated the call and that you are speaking with a legitimate representative of your bank or a known merchant.
Be cautious about account number requests via email or text message. Your bank will never ask you to confirm your account number by email. If you receive an unsolicited request, do not respond; instead, call your bank directly using the number on your statement or card. Scammers sometimes pose as banks to collect account numbers for fraud.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 16-digit number printed on the front of a credit or debit card. Your account number is the number associated with your bank account or credit line. They are related but different — the card number is tied to the card itself, while the account number is tied to the account the card draws from.
Can someone use my account number to steal money?
Your account number alone is not enough to steal money, but it is a piece of information a scammer would want. Combined with your routing number, it can be used to set up unauthorized ACH transfers or bill payments. This is why you should not share your account number with unknown callers or in unsecured emails. If you suspect fraud, contact your bank immediately.
Do I need my account number to check my balance?
No. You can check your balance by logging into your online banking portal or mobile app using your username and password, by calling your bank's automated phone line, or by visiting an ATM. You do not need to provide your account number for these actions — your login credentials are enough.
What happens to my account number if I close my account?
Once you close an account, that account number becomes inactive and cannot be used for new transactions. If you have automatic payments or direct deposits set up with that account number, they will fail. Before closing an account, update any recurring payments or deposits to a new account number or payment method.
Can I request a new account number without closing my account?
Most banks do not issue a new account number for an existing account unless the account has been compromised by fraud. If you are concerned about security, contact your bank to discuss your options. In most cases, the bank will recommend monitoring your account closely rather than changing the number.
