Who do I contact at Avalara to get my Authentication code for the state website?


You need your Authentication code for the state website.


Avalara Returns


  • Have an Account Admin or Company Admin level user contact Support, for urgent requests please call

    • To see a list of Account Admin and Company Admin users go to Settings > Manage Users > Role lists the user role

  • We will send any information sent to us on your behalf to an authorized user

  • NOTE: Starting in 2019, authorization codes are being set up with an email address. This email address allows both the Avalara Returns team, and any Account Administrator role in AvaTax to receive authorization codes from the states. Please check junk/spam boxes if your Account Administrator doesn't see the email in their inbox.
