@boriquaboy115 FOG is an opensource project. AFAIK there is no physical location where The FOG Project exists. One of the developers might know for tax reasons if there is a specific mailing address.
As I said, The FOG Project is an opensource project with developers around the world. The senior developer that approves releases is based in the USA.
If you need this information for federal regulatory submission reasons, you may have a hard time getting opensource software approved for use.
