Use of affiliate ID on mutiple sites

Hi, I'm thinking of joining the ebay affiliate program. If I obtain an affilliate ID for my current website am I free to use the same ID on other websites I may develop in the future without any kind of reregistration?

Thanks much!!

 

I have been able to without any problems

 

You could use the same affiliate id for more than one site but it is best to add all your sites to your profile so you can get a tracking id for each and then you can see which sites are making money and which aren't.
