Credit Card Number Validator is a free utility to help you check validity of a credit or debit card number. Credit Card Number Validator verifies credit or debit card numbers right on your PC without going on-line or transmitting sensitive information from your PC. Credit Card Number Validator uses LUHN formula (Mod 10) for validation of primary account number.
Credit Card Number Validator can only validates the integrity of the number combination, not the credit or debit card itself.
Credit Card Number Validator detects and displays credit or debit card type early depending on the first digits of the card number. It only verifies whether or not a credit or debit card checksum is valid; it does not validate the credit or debit card account. In order to verify a credit or debit card account, you will need software that can access credit and debit card networks, and, typically, submit authorization request on the card account.
FEATURES
- Validates credit or debit card numbers
- LUHN10 (MOD10) checksum algorithm
- First digits verification
- Automatically determines type of the credit card
- Validates any Visa, MasterCard, AMEX, Discover, or Diners Club credit card numbers

CVVs, CVV2s, CVCs, and Indent CVCs are 3-digit Card Verification Values or Card Verification Codes that are all calculated using the same CVV algorithm. These values are required by payment systems such as Visa and MasterCard to authenticate their credit or debit cards. Different names are used to refer to the values depending on the particular payment system, the location of the value on the card, and the parameters passed to the CVV algorithm. To calculate a 3-digit CVV, the CVV algorithm requires a Primary Account Number (PAN), a 4-digit Expiration Date, a 3-digit Service Code, and a pair of DES keys (CVKs). Besides the obvious CVV variations provided by different PANs and expiration dates, most card issuers will use different CVKs for different batches of cards. Cards can be grouped by bank, by ATM network, or by other means of identifying a certain group of cards. Cards in the same batch will often use the same service code. This service code to the CVV algorithmis usually non-zero. One CVV variant, now commonly called CVV2 (Visa), or Indent CVC (MasterCard), uses '000' as the service code parameter to the CVV algorithm. Sometimes a card will have both a traditional CVV and a CVV2. Another variation to the CVV algorithm can be introduced by changing the format of the expiration date. While the date is always the concatenation of the 2-digit month (MM) andlast 2 digits of the year (YY), it can be in either YYMM or MMYY formats. For instance, Visa CVV2s are usually calculated using the YYMM format
