An error 400 message screen may be shown in the Zip app when adding or updating a card.

This typically occurs due to a CVV code, zip code, or other card information being entered incorrectly. If you are seeing this message, please update your Zip app and try adding the information again.

If you have already tried that, please visit the [Customer Portal](http://customer.us.zip.co/) to update your payment information.
