Hi VeronicaITS-
The use of gift cards is not recommended. PayPal uses information tied to credit / debit cards as part of the process of confirming account holders' identities and gift cards do not have that information.
For example, we may ask for a 4 digit code that appears on the credit card statement to confirm that the account holder has access to the financial records of the card. Since gift cards are not tied to a specific account holder that information is not available. Some gift cards are able to be added to a PayPal account, but there is no guarantee that you will have full functionality or even that the card will be able to be added at all.
Thanks,
Jason
