It says, Account is not verified and not authenticated.

How do I verify it AND make it authenticated?

Thanks

Add a banking account, I think that's how you do it

How do you add a banking account?

Also, whenever I try to enter my VISA credit card number, it's not valid. How do I make it valid?

By putting a billing address, and making sure it is right.
you get a banking account by going to a bank and make one.
You must be 18+ to have one though, that's how you get checks

Thanks, made already.

I searched it in google, how to verify your paypal account.

It says, one of the ways are to add and confirm a bank account.

Well, how do I confirm a bank account and use it to verify my paypal account?

Go to a bank and make a bank account with that bank
Then you can deposit your money into your bank account, and it will show up on paypal

Thanks, but, I don't wanna do that.

Is there alternate way?
