Validating an American Express Credit Card Number

Validating an American Express credit card number is crucial for ensuring the accuracy and legitimacy of the card during transactions.

2. Verify that the first two digits are either 34 or 37. These prefix numbers are unique to American Express cards.
3. Proceed to check the remaining digits, excluding the check digit. These digits consist of the issuer identification number (BIN) and the cardholder’s account number.
4. Apply the Luhn algorithm, also known as the Mod 10 algorithm, to the remaining digits. This algorithm verifies the validity of the card number by performing a series of calculations.
5. double each alternate digit starting from the rightmost digit (excluding the check digit). If the result of doubling a digit exceeds 9, sum the individual digits of the product.
6. Add up all the digits, including the doubled digits and the undoubled digits.
7. If the total sum is divisible by 10, the credit card number is valid. If the sum is not divisible by 10, the card number is likely to be incorrect or invalid.
8. Always double-check the validity of the card number and cross-reference it with the cardholder’s information to ensure accuracy and prevent fraudulent activities.

Validating an American Express credit card number using the steps mentioned above can help detect any potential errors or discrepancies in the card number.
