Credit Card Checker
Our credit card checker is used to validate credit card numbers. You can use it to see if a card number is valid or not. There are many different reasons why you may want to check a CC number. You could be looking to make a purchase online and you may 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 in order to validate the credit cards that your users enter in check-out forms.
Credit card numbers have to be written in a specific method. They have to fulfill a particular algorithm called the Luhn algorithm. Our CC 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 cc checker to see if your credit card numbers are valid.
- Enter the CC number 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
It provides detailed information about the entered credit card. You can see the MII (Major Industry Identifier), bank name, bank country, BIN number, PAN number, and so on. All of these details can help you learn more about the card that you are verifying.
2. Quick processing
Our credit card validator works very fast. You can check cc numbers in a matter of seconds. All you have to do is 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 yet another excellent feature that 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 CC checker, you can verify card numbers from a number of different issuers, such as VISA, MasterCard, American Express, etc. We support all of the popular card issuers and banks situated around the globe.
If you want to give this a try, you can generate random CC numbers using our free credit card generator and test them with the credit card checker.
Understanding the Luhn Algorithm in Detail
In order to verify whether the provided credit cards are valid or not, our credit card checker uses the Luhn algorithm.
The Luhn algorithm involves calculating/computing a provided string of numbers and then 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 string is valid in terms of the Luhn algorithm.
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 double digit so it will be added together like 1 + 2. The same goes for 16 and 14.
- After the doubling and adding is done, all the modified digits will take the place of 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
- If the final sum is divisible by 10, then the number is valid in terms of the Luhn algorithm. If the final sum is not divisible by 10, like 73, then the number is not valid.
Frequently Asked Questions
What is a credit card validator?
A credit card validator or checker is an online tool that verifies whether a credit card number is valid/genuine or not.
How does a cc checker work?
It works by checking the card number against the Luhn algorithm. This algorithm computes the number and the checksum (the last digit) to satisfy a particular condition. If the condition is fulfilled, the number is considered valid; otherwise, it is not.
Why is it important to use a credit card checker?
It is important to use a CC checker live because it can help you see if a particular card number is fraudulent or genuine. If someone gives you a credit card to initiate a purchase or if you are using a dummy number for testing purposes, you can test its authenticity using a credit card number checker.
Is it safe to enter my credit card information into a credit card verification tool?
Yes, it is completely safe to enter a credit card number into our card validator. We don’t save your details or use them in any way. The validator is only designed to check the validity of the number and nothing else.
What is the difference between a credit card checker and a credit card generator?
A credit card checker verifies the details of a CC by using the Luhn algorithm. While a credit card generator, on the other hand, is a tool that creates random credit card details. These details are realistic and can be validated with a CC checker but they don’t actually exist.
