What Is the Account Number on a Debit Card?
According to the 2021 Diary of Consumer Payment Choice released by the Federal Reserve Bank of Atlanta, U.S. consumers make 60% of their transactions with payment cards (debit, credit, or prepaid). Despite the popularity of these payment methods, many users are not familiar with card-related terminology, including the meaning of numbers on payment cards.
One of the most common questions card users ask is—“What is the account number on a debit card?”.
This guide will explain the meaning behind all the numbers on your debit card. You will also learn about the safety measures necessary to protect your cards when shopping online.
What Is a Debit Card Account Number?
The account number on a debit card technically refers to the 16-digit primary account number (PAN), the unique card identifier located on the front of the card. However, PAN is not a common term in consumer circles. Users typically call it the debit card number, and it is used to make purchases online or at point-of-sale (POS) terminals.
Card numbers identify the card issuer and the associated user account. The table below presents what each sequence of the debit card number means:

Is the Debit Card Number the Same as the Bank Account Number?
While a debit card number is associated with your checking account, it is not your bank account number.
A bank account number is a unique sequence of digits (can be alphanumeric) assigned to any user opening an account with the bank. It generally consists of 8–12 digits, but an Automated Clearing House (ACH)-enabled bank can issue account numbers of up to 17 digits[1]. Below is the standard account number length for different banks:
A bank account number acts as the principal identifier that tells processing algorithms to extract or deposit money for a specific customer. While digits 7–15 on a debit card are linked to your bank account number and help move funds when requested, these numbers are independent of each other.
A debit card is linked to one bank account, but you can typically request more than one debit card attached to a single checking account. The following table summarizes the differences between debit card and bank account numbers:
Is the Bank Account Number on the Debit Card? Where Can You Find It?
Debit and credit cards typically don’t display the user’s account number for security reasons. You can locate this piece of info by:
- Checking your bank statement—Your bank account number may appear on bank statements (including e-statements) under an appropriate label (like Account Number, Customer ID, or similar). It’s usually toward the top-right, before the main table outlining withdrawals and deposits.
- Logging in to the bank’s website or app—If you have enabled internet or mobile banking, log in to your customer account to check your account number. Depending on the platform, the number can be displayed on the homepage or accessible under tabs such as Account Information, Settings, or similar.
- Checking the paper checks (if provided)—Most paper checks display three sets of numbers at the bottom[3]: The nine digits to the left are your bank routing number, the middle set of digits is your bank account number, and the digits to the right represent the check serial number.
- Contacting your bank—Considering the sensitive nature of the request, be prepared to provide a government-issued ID or answer some security questions first.

Protecting Your Bank Account and Debit Card Numbers—Risks and Solutions
Protecting bank and card data has become increasingly complicated with time as criminals have developed new and advanced ways to hack into users’ accounts.
According to a 2022 report released by the Federal Trade Commission, customers lost almost $8.8 billion to fraud throughout the year—a 30% jump from 2021 figures. Out of the 2.4 million fraud reports, 1.1 million were related to identity theft.
Below are the most frequently used techniques to extract bank account and debit card numbers:
- Phishing schemes—Phishing is a common social engineering tactic used by scammers to trick you into revealing your financial data. The fraudsters may pretend to be a bank representative over the phone and ask you for your card number or security code. They may also send emails or texts pretending to be a trusted or familiar organization and prompt you to share your bank account information.
- Gaining access to your online account using malware—Malware is typically distributed via email and may compromise your personal, business, and financial data if downloaded on your device. For example, Xenomorph[4], a newly created Android malware, can help criminals steal one-time codes and access your funds remotely. You should exercise caution online and never download suspicious files or attachments from a website or email you don’t trust.
- Buying your card data from the dark web—Stolen payment card data went for anywhere between $20 and $120 on the dark web in 2021. The information is typically acquired by breaching e-commerce websites that store users’ personal and financial data.
To mitigate the risk of your debit or credit card numbers being stolen by hackers, start masking your real payment information with virtual cards.
Use Virtual Cards and Protect Your Banking Information Online
Virtual cards are unique, randomly generated 16-digit numbers with their own expiration dates and CVV codes. They are connected to an actual funding source (such as your bank account or debit card) but hide your real card or bank information from the merchant. In case of a security breach on the merchant's website, the hacker can only access your virtual card number while your real card or bank data remains protected.
Virtual cards can be for one-time or multiple use, depending on your virtual card provider. While many banks and independent providers offer virtual cards, you should choose a service that enables extensive control of your finances, like Privacy.
