Hi michiabendanarroco! After you've entered your GCash American Express Virtual Pay details on your PayPal account, you should send an email to firstname.lastname@example.org and ask for your 4-digit PayPal code. Don't forget to state your full name, the mobile number you registered with GCash, and your GCash American Express Virtual Pay card number. They'll send you your 4-digit code within 48 to 72 hours. After inputting said code, you will now have the PayPal Verified status.
Thank you verymuch TJ
