Find your company ID number

This article applies to:AvaTax

When you create a company in Avalara, it's assigned a unique ID number to differentiate it from every other company created by users of Avalara. Avalara Support or other Avalara teams may ask you for a company ID when they're troubleshooting problems or researching issues on your behalf.

To find a company ID number:

  1. Select Switch company and choose the company that you want to find the ID for.
  2. Examine the web address after Avalara has finished loading.
    Your Avalara homepage web address is something like "" The ten digits following "a/" are your Avalara account number, and the four to seven digits following "c/" are the ID number of the currently active company.
