Most online shopping carts have a security measure in place to verify the “billing address” and name associated with the credit or debit card. When your card was purchased, your address and/or name may not have been assigned to the card. To update this information:
Go to omnicard.com/cards and select “Register Card” from the options. You will need to enter the 16-digit card number and the 3-digit CVV/CVN from the back of the card and then select the “Register Card” button. Then follow the instructions to input your home address.
Contact Customer Service at 1.877.357.4975.
Then when using the card online, make sure to use the address you registered the card under as the Billing Address in the shopping cart.
