On Westpac Mastercard® and our prepaid cards, you'll find the security code on the back of your card - it's the last three digits on the right hand edge of your signature panel.

This three digit security code is known as a CVC (Card Verification Code) or CVV (Card Verification Value).

If you can't read your code, call our Cards team on 0800 888 111 (Monday to Friday 7am to 8pm and Saturday and Sunday 8am to 5pm), or from overseas call +64 9 912 8000 (international toll charges apply), and we can let you know what it is.
