chosen: Generally, the first four digits of a credit card number are predetermined by the credit card issuer, based on the account holder's billing address. However, as a general rule, the first 4-6 digits are never predictable and will always vary from card to card. It is also not possible to reliably determine the rest of a credit card number based on just the first few digits.
