How To Identify Credit Card and Debit Card by Number (2024)

In 2021, the Federal Reserve reported that about 84% of adults in the U.S. owned a credit card, and the total number of users is showing an upward trend. According to the Nilson Report, the number of payment cards used worldwide is expected to reach 28 billion by 2027.

Despite the widespread popularity of payment cards, users may not know much about the cards they use on a daily basis—and few people actually know that the numbers stand for something, let alone what that is.

What Numbers Are on a Credit Card?

A credit card typically contains the following numbers:

‍

This specific sequence and location of numbers are the standard worldwide, but there can be some minor exceptions. For example, American Express^® cards typically have 15 digits, while Visa^®, Mastercard^®, and Discover^® use a 16-digit format.

Besides these elements, a credit card contains:

• The cardholder’s name
• The bank’s logo
• The payment network’s logo
• A smart chip
• A magnetic stripe
• Your signature
• A hologram
• The bank's contact details

The Sequence of the Digits in Credit Card Numbers

The card digits and the card number order are strategically chosen and placed. They reveal crucial information about the card, the cardholder, and the card issuer. Discover what they mean in the table below:

Note that not all credit card numbers follow this exact structure. For example, the checksum on a Visa might be digit 13 instead of the last digit.

The Meaning Behind the Bank Identification Number

The Bank Identification Number (BIN), also known as the Issuer Identification Number, is the first 4–8-digit sequence at the beginning of the card number. As you can see in the table above, the BIN contains the industry identifier and indicates the financial institution that issued the card.

The BIN system was established by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). Its primary purpose is to increase the efficiency and security of payments.

The Bank Identification Number helps merchants evaluate transactions and detect fraudulent or stolen cards. When initiating a transaction, you need to enter your card number, expiration date, and CVV or CVC. The issuer then receives a request to verify the account, the availability of the funds, and the compliance with national law. The BIN gives merchants all they need to validate the information and process the transaction.

All U.S. cards have a BIN. Here are the starting numbers that correspond to the four most common card networks:

1. American Express—3, particularly 34 or 37
2. Visa—4
3. Mastercard^®—5
4. Discover—6
   ‍

The digits that follow these can indicate the card’s type, level, and the issuing bank’s location.

Do Credit and Debit Card Numbers Differ?

Debit card numbers work on the same principle as their credit card counterparts. The first 4–8 digits represent the BIN, while the remaining ones include the account number and checksum. As with credit cards, the order is subject to change depending on the issuer.

You can’t tell whether a card is associated with a debit or credit account based on numbers alone. Still, you can usually find that out by looking at the card as most of them have a “credit” or “debit” label somewhere on the card.

The Importance of Protecting Your Credit and Debit Card Information

Card numbers can fall into the wrong hands and become misused, so protecting your data during transactions is crucial.

According to Security.org, 65% of U.S. citizens were victims of credit card fraud at least once in their lifetime. In 2022, 44% of credit card users had to deal with two or more unauthorized charges, a significantly higher number than the previous year (35%).

Fraudsters use an array of tactics, such as phishing, pagejacking, and skimming, to steal cardholders’ personal information. Technological advancements enable fraudsters to constantly develop new and more intricate techniques.

After acquiring the victim’s financial and personal information, the perpetrators can take advantage of it in multiple ways. They can make fraudulent transactions, withdraw funds, open new accounts, or apply for credit. These actions cause the victim financial loss and affect their creditworthiness, often resulting in long-term consequences.

On the upside, technology has also brought about more robust and accessible security measures that help protect sensitive information—and no solution is as versatile as the virtual card.

How Virtual Cards Help Prevent Card Fraud

A virtual card is one of the best ways to safeguard your financial information when shopping online. It’s an auto-generated, unique 16-digit number with its own security code and expiration date that’s connected to your bank account, debit card, or credit line.

You can use a virtual card to make purchases without exposing your actual card number and other financial information at checkout.

Among many benefits that using virtual cards brings, the most obvious are:

1. Security and privacy—As it stays hidden, your bank and card information is protected even if a data breach occurs.
2. Spending restrictions—This feature helps control your spending and keep it within a budget.
3. Merchant-locking—Some virtual card issuers allow you to tie the card to a specific merchant, which means it can’t be used elsewhere even if a hacker gains access.
4. Instant card pausing or closing—You can typically pause and close the virtual card instantly without affecting the status of your real card or bank account.

Reinforce the Security of Your Data With Privacy Virtual Cards

Privacy Virtual Cards enable you to shop online and enhance the security of your transactions, fortifying your defense against the ever-present risk of identity theft.

While some banks offer virtual cards to registered account holders, Privacy gives you more freedom as you can request and generate Privacy Cards with your existing account, irrespective of the associated bank. After creating a card, you can lock it to a specific merchant or have it automatically close after a single purchase, minimizing the damage in case of a data breach.

You can set a spending limit on every card or transaction and minimize the risk of getting overcharged. Privacy will automatically deny transactions that go over the designated limit. This can be beneficial for keeping your subscription services under control and ensuring merchants don’t charge you more than you’ve agreed to.

You can also pause and unpause Privacy cards at any time. If you notice any suspicious transactions on your virtual card, you can close it instantly without worrying that it will affect your actual card or bank account. This feature is also convenient for preventing unwanted subscription charges. Once you pause or close the virtual card, Privacy will block all further charge attempts. Note that you still have to reach out to the merchant and cancel the subscription directly.

Privacy is BBB®-accredited, PCI-DSS compliant, and includes various safeguards to protect users’ data.
