You need to notify Commonwealth Bank (CBA) immediately if your credit card is lost or stolen or if your PIN is divulged. To report a card lost or stolen, call anytime on:
131 576 (within Australia)
+61 13 1576 (reverse charges from overseas).
You can call CBA 24 hours a day, 7 days a week. It's important that you notify the bank as soon as possible. If you do not notify the bank within a reasonable time, you may be liable for unauthorised transactions.
What happens next?
CBA will place a stop on your lost or stolen credit card and issue you with a new credit card. You will receive a new credit card within 3 to 5 business days, which will have a new credit card account number. If you are overseas when your card is lost, CBA will organise to have your new card and PIN couriered to your overseas address at a cost of $50.
