Credit cards will be invalid if they are not activated for 3-5 years. Every credit card has a validity period, usually 3-5 years after it is issued. During the validity period of the credit card, the credit card is not activated and will not automatically expire. If the activation of the credit card is not completed within the validity period, it means that the card is invalid, but it does not mean that the credit card will be cancelled. If the card is no longer needed, you still need to cancel the business.

The validity period of a credit card is generally printed under the card number on the front of the card, and the four numbers are separated by "/",with the month in front and the year behind.
