Credit cards have no activation period, that is, if you don't open the card and don't use it, you can activate it at any time. However, because the credit card itself is valid, that is, there is a sign similar to "09/ 16" under your card certificate, which means that this card will be invalid in September of 20 16. When the credit card expires, it must be renewed at the bank, and a new card needs to be activated.

Generally, credit cards are valid for more than three years, so they can be activated within two or three years. The card has expired. If you want to continue to use it, you should replace it with a new one. If you don't want to use it, you should remember to cancel the account.
