Hello, the validity period of credit cards is generally 5 years and 8 years. Cardholders can check the validity period of the card through the two sets of numbers under the credit card number. It should be reminded that users cannot check the validity period of China Merchants Bank credit cards through customer service and self-service channels. One month before the standard validity period on the CMB card, the bank will conduct an audit on the cardholder's card usage records. If the card is in good condition, the China Merchants Bank Credit Card Center will automatically issue a new card.
