How To check if the CC is dead or alive?

To use your credit card for purchases and other transactions, it must be open, active, and in good standing. Your credit card can become inactive and thereby unusable in certain circumstances.

There are a few ways your credit card can become inactive. If you haven’t used your credit card in several months, or years even, the credit card issuer may deactivate your credit card. Or, if you’ve fallen behind on your payments, your purchasing privileges may be suspended.

Call Customer Service

The simplest way to clear up any question about whether your credit card is still active is to call your credit card issuer and ask. Call the number on the back of your credit card to contact customer service and the representative will be able to give you the status of your account. While you're on the phone, customer service can reactivate an inactive credit card so you can make purchases on the card.

Try to Use It

If for some reason, you don’t want to call customer service, you can test your credit card’s status by using it to make a purchase. A declined card would be a sign that your card is no longer active, but it could also mean a number of other things, e.g. the card is expired or you've reached your credit limit.

Use a Credit Card Verifier App

With this app, you only enter the card number and it will do the work for you. It will tell you if your card is dead or alive
