What is Anonymous Profile ID?

If your AddThis code contains a profile ID that starts with xa- you’re using what we call an Anonymous Profile ID. These are generated when an unregistered user visits one of our code generation pages. We use these so we can collect analytics for you in the event that you choose to register for an account.

To get access to analytics collected with the anonymous profile ID first register for an AddThis account at and then send an email to with the subject “Anonymous Profile ID” and, the anonymous profile ID, and the email address you used to register. We’ll apply the analytics to your account and let you know when they’ll be available.
