If you lost your Avant Credit Card, then call Avant customer service at (855) 752-7012 to report the lost card. They will request some security information in order to verify your identity before sending a replacement.
How to Report a Lost Avant Credit Card
- Call Avant customer service at (855) 752-7012.
- Inform the customer service representative that you’ve lost your credit card.
- Provide any requested information, such as your date of birth or the last four digits of your SSN.
- Ask the Avant representative to cancel your old credit card and send a replacement.
You should receive a replacement card within 10-15 business days. When you receive your replacement card, you’ll need to activate it before you can make purchases. You can do that online or by calling (855) 752-7011. If there are any recurring charges linked to the old Avant Card, make sure to update those accounts with your new card information.
Finally, it’s important to note that your Avant Card is covered by $0 fraud liability, which means that you will not be held responsible for unauthorized purchases made with your card while it’s lost. That said, you should still report any unauthorized charges as soon as you notice them on your billing statement.
