Do you have a bank account linked and confirmed ?? If yes, you can use that to tranfer funds to your PayPal account balance (or Wallet). You don't need any code to buy online - depending on how the merchant is setup, assuming they offer PayPal, you choose that option, login to your account and pay.
PayPal will first check your PayPal balance to see if there is enough money to cover the payment.
If you have enough money in your balance, PayPal will use it to make the payment.
If you have some money in your PayPal balance but not enough, PayPal will use that balance plus another payment method linked to your account.
If you don’t have any money in your PayPal balance, PayPal use another payment method linked to your account.
When you don’t have a PayPal balance or don’t have enough in your PayPal balance, PayPal will use your bank account as the default payment method unless you select a different way to pay.
To make sure you’re using the payment method you want, check the Review Your Payment page.
Additional Notes:
You will be able to select a preferred funding method for payments made through the regular checkout process as well as Goods and Services via Send Money. You will also have the option to select a different preferred method for online purchases vs. in-store purchases.
If you have PayPal Smart Connect, PayPal Plus MasterCard, PayPal Extras MasterCard, PayPal Debit MasterCard, or eBay MasterCard, you can make that your default payment method. Once a payment has been sent to another PayPal account, the funding source cannot be changed.
