Provider Websites

So I've been looking at the websites for various providers in the showcase area and I've come across several that require a registration of some kind before you are granted acess. It's not the type of registration that costs. They are supposedly free. However, when I try to to the site after resistering a window pops up and says I need to enter the pin number or a code number to get final acess. Trouble is there was no pin number or code number in any of the registration process. Can someone tell me if you have had the same problem and how or if you solved it?

Thanks
