Please be patient. Your code is probably valid, but it will not give you access to purchase your badge(s) until the Priority Registration Period opens on 1/10/2022 @ 12 PM PST. If it still does not work once the presale window opens, then submit a support ticket and remember to include both your name, email address, and the code you were issued so we can assist you.
Also, if you already used your code to place an order, then your code is now expired and you will need to wait until the public sale opens on 1/24/22 to purchase additional badges. Your access code only allows you to place a single (1) order, but you are able to purchase up to 4 badges per order.
