Registration of numero d'activite for formation professional


Are there any trainers in this group who offer open courses and have obtained a numero d'activite for formation professional?

I had previously had a number when training in corporates however this has long gone and I wish to register again however it seems the rules have tightened up and you need a contract from an organisation in order to register. This would imply that you can not register if you offer open courses? As the courses I run will be attractive for people using their DIF allocation this is important for me.

any help/advise would be really welcome.
