I hate VBV in general - I consider it security theatre and the only thing I have ever seen it do is make it difficult or impossible to allow me to use my card.

That said, my understanding is that Chase used a different implementation of VBV and you can not register for it using Visa's site like you can for other cards.

That said, I haven't had issues with this on UA.com - probably since it was CO.com where I did have issues in the past. I also had issues with many sites when I was living in India where it did very similar things to where you are discussing. In India, they also use a technology called 3D secure, which I think in many cases is incompatible with VBV. For a couple of vendors, I was able to avoid the problem by giving Chase the info. and them specifically allowing it and it seemed to work afterwards. For others, some local sites wouldn't actually accept US or foreign-issued cards (unlikely an issue with UA.com). For others, they claimed they should accept it, but I could never get it to work.
