Hi Support,

What **BC** means in Mautic’s official documentation

Consulting information about contact tracking in the official documentation of Mautic I see that reference is made to “BC” in terms of cookies but I am not clear what **BC** refers to.

It means **backwards compatibility** - so in those cases the cookie value was used in older Mautic versions and we still have it in the docs, in case there might still be old data using those values.
