Address verification (AVS)
To prevent fraudulent charges to your account, most e-commerce sites use address verification system provided by card processors.
Your bill to address has two numerical portion: street number and zip code. They are used to verify card holder info.
One of these two must match with your monthly billing statement address, most likely your home or business address, in order for your credit card to proceed and your lollicupstore.com order to complete.
C V V is the three or four digit code on the card that is also used to verify you. This acts as a pin for online transaction. Merchants (including lollicupstore.com) do not save this code, thus you must enter every time you purchase.
C V V must match for order to complete. Wrong C V V will always result in decline of order.
