Many friends have lost their credit cards, or the cards are worn out and can't be used normally, so they will reissue a new card. After getting a new card, many people will have various questions, such as whether the new card needs to be reactivated after the replacement, whether to set a password, etc. Here is a brief introduction. do I need to reactivate my credit card after it has been replenished? As we all know, in order to ensure the safety of using the card, the new cards sent by the bank are not activated, and the cardholder needs to activate them himself. No matter whether the card is issued for the first time or the new card is reissued, it is the same, so that others can be prevented from stealing the card, so the credit card needs to be reactivated after being replenished. The activation method is very simple. You can use the reserved mobile phone number to call the service hotline of the issuing bank and complete the activation step by step according to the voice prompt. Or through the credit card official website channel, find the credit card activation option, enter the activation page, enter the card number and cardholder ID card, and get the verification code to activate. After the reissued new card is activated, the old card will be invalid immediately. Even if it does not expire, the card can no longer be used. The accounts, points and limits of the old card will be automatically transferred to the new card. If the credit card has outstanding debts, you can transfer the money to the old card number or the new card number. Anyway, the old and new cards can receive repayment normally. Some friends will ask if it is necessary to reset the password after the credit card replacement card is activated. This is not necessary. The new card uses the password of the old card. If the old card had a query password and a transaction password before, the new card does not need to be reset. Of course, if the cardholder feels unsafe, he can call the service hotline of the issuing bank to transfer the manual service and change the password with the help of customer service. The above is the introduction of "Is it necessary to reactivate the credit card after it is replenished?" I hope it will help the crackdown.
