Hi @asfia545
Welcome to the PayPal Community.
When you add your card to your PayPal account, we will ask you to confirm this card.
PayPal will make a small charge to your card. After the card is confirmed, we will immediately refund the card. Your card issuer will credit your card balance within 30 days from the date of the refund.
The charge appears on your card statement with a 4-digit code and the word PAYPAL. If you view your card statements online, you can check for the code in a few days. Otherwise, check for the code when you receive your next statement in the mail.
For more help on this, see: How do I confirm a debit or credit card that I've linked to my PayPal account?
I hope this helps, have a lovely day!
