How long a credit card can last depends on two factors. First of all, the age of applying for a credit card is generally required to be between 18-65 years old, but the age requirements for applying for a credit card master card and a supplementary card are different, and different banks have different regulations. Secondly, credit cards have a certain validity period, ranging from three to five years. If the validity period of the credit card is exceeded, the cardholder can continue to apply for the credit card within the age range specified by the bank.
