When I try registering a Mos Card, I get the following error: "Please try entering the correct Mos Card information again at a later time."

You cannot check out using a Mos Card that another customer has already added to their account. In addition, the same Mos Card also cannot be added to multiple Mos Net Order accounts with different email addresses, even if they all belong to the same person. Please either check out using the account that the Mos Card has already been added to or remove the card from that account from the official Mos Burger websitethen use a new account to check out again with the Mos Card.

If you are still unable to check out using the Mos Card, please contact Customer Support.
