A 4-digit PayPal code is generated using the instructions above link and a 1.95 USD [or 100 PhP] charge usually appears on the credit/debit card statement 5 business days after, depending on the card-issuing bank. If you do not have online access to your credit/debit card statement, you have the option to look for the code on the printed statement in the mail.
Your 4-digit PayPal code will be printed next to the word "PayPal", in the item description section of your credit/debit card statement. The code sequence appears as PayPal*1234CODE or PP*1234CODE. You will need the first 4 digits. We will return the 1.95 USD [or 100 PhP] charge back to your card once you confirm the latter using the 4 digit PayPal code.
