Credit Card Validator

Credit Card Checker

Our credit card checker is used to validate credit card numbers. You can use it to see whether a card number is valid. You may want to check a CC number for many different reasons. You could be looking to make a purchase online and want to ensure that your card number is valid. Or, you may want to use a CC checker as an integrated API for your e-commerce website to validate the credit cards that your users enter in check-out forms.

Credit card numbers have to be written using a specific method. They have to fulfill a particular algorithm called the Luhn algorithm. Our validator quickly checks the provided number to see if it satisfies the Luhn algorithm or not.

How to Use Our CC Checker?

Here is how you can use our tool to see if your credit card numbers are valid.

• Enter the CC number (Upto 5 numbers) in the provided space
• Click on the “Validate Now” button
• View/download the results

And that’s it.

Features of Our Live CC Checker

Here are some of the features that you can enjoy with our card validator.

1. Provides Detailed Information

Our CC checker provides detailed information about the entered credit card number. You can see the MII (Major Industry Identifier), bank name, bank country, BIN number, PAN number, etc. These details can help you learn more about the card you are verifying.

2. Quick Processing

Our credit card validator works very fast. You can check cc numbers in a matter of seconds. You must enter the number in the provided space and press the button to start the process. After that, it takes a second, and all the information for the card is provided (if it is valid).

3. Downloadable Results

This is another excellent feature you can use with our CC checker. After you check the results, you can download them to your device. This can help you share them with another person if needed. The credit card check results can be downloaded in JSON, XML, and CSV.

4. Easy to Use

Our CC number validator has an intuitive and easy-to-use interface. You don’t have to go through any confusion when using it. All you need to do is enter the number in the field that is clearly provided at the top of the interface.

5. Supports a Wide Number of Card Issuers

With our credit card checker, you can verify card numbers from several issuers, such as VISA, MasterCard, American Express, etc. We support all of the popular card issuers and banks globally.

If you want to try this, you can generate random CC numbers using our free credit card generator and test them with this checker.

Understanding the Luhn Algorithm in Detail

Our credit card checker uses the Luhn algorithm to verify whether the provided credit cards are valid.

The Luhn algorithm involves calculating/computing a provided string of numbers and verifying the final checksum to see if it passes a particular condition. The string of numbers is specifically computed and then added up to a particular checksum. If the checksum is divisible by 10, then the Luhn algorithm validates the string.

Here is an example. Take this number: 1234 5678 9123 4567

These steps are taken to compute it:

• Starting from the left, every 2nd digit is taken and doubled. In this case, the numbers would be 2, 4, 6, 8, 1, 3, 5, 7. When doubled, the numbers would become 4, 8, 12, 16, 2, 6, 10, 14
• All the numbers that are in double digits are added together. For example, 12 is a double-digit so that it will be added together like 1 + 2. The same goes for 16 and 14.
• After doubling and adding, all the modified digits will replace the original ones in the first string.
• The final string becomes 1438 5377 9226 4165
• All of these numbers have to be added together. 1 + 4 + 3 + 8 + 5 + 3 + 7 + 7 + 9 + 2 + 2 + 6 + 4 + 1 + 6 + 5 = 73
• The number is valid for the Luhn algorithm if the final sum is divisible by 10. If the final sum is not divisible by 10, like 73, then the number is not valid.
