What Is Credit Card Verification?
Credit card verification confirms that a card number conforms to standardized rules and formats without contacting the issuing bank. By leveraging algorithms like Luhn’s checksum test, our tool instantly determines whether a number is potentially valid and provides associated card data.
How Our Validator Works
Using the Luhn Algorithm and industry databases, our validator performs several checks:
- Luhn Algorithm Check: Validates the card’s checksum digit.
- Major Industry Identifier (MII): Identifies the issuing industry from the first digit.
- Bank Identification Number (BIN/IIN): Verifies the first six digits against known issuer records.
- Card Network: Determines Visa, MasterCard, AmEx, Discover, etc.
- Primary Account Number (PAN): Confirms the unique account segment.
- Expiration Date Check: (if provided) Ensures date format and future validity.
If all checks pass, you’ll see a confirmation message: "Your credit card is valid." Otherwise, an error will indicate why the card failed validation.
How to Read Your Validation Report
Understanding each element helps you quickly act on the results:
- MII (Major Industry Identifier): The first digit, ranging from 0–9, which categorizes the card issuer’s industry (e.g., 4 = Banking & Finance).
- BIN/IIN: The first six digits that uniquely identify the issuing bank.
- Network: Shows the payment network (Visa, MasterCard, etc.) and any special program (e.g., corporate or prepaid).
- PAN Length: Confirms card number length (commonly 13–16 digits, depending on issuer).
- Checksum Result: Indicates whether the Luhn test passed or failed.

About the Luhn Algorithm
Also known as the MOD 10 algorithm, the Luhn test is the industry standard for verifying card numbers’ integrity. By doubling alternating digits, summing individual digits of the products, and comparing the final checksum to the last digit of the card, it determines validity in milliseconds.
Extended FAQs
- Can I validate multiple cards at once?
- Yes, you can enter multiple card numbers separated by commas or line breaks to batch-process validations.
- Is my data saved?
- No. All card numbers are processed client-side and never stored on our servers.
- Can I use this for production payments?
- No. This tool is for format and integrity checks only. For live transactions, always integrate with a certified payment gateway.
