Chances are unless you post the actual company and someone else here happens to use it we won't be able to tell you for sure. Amex and visa will possibly have different codes, but hopefully you can argue to chase it falls under that category in the case that it doesn't automatically hit the right category.

Good news is either way you'll get the 25,000 points sign up and the 25,000 points for spending over 10k with that one spend. So either way try it out and get 50,000 points. That's still about 3.4x UR points.

I think the risk is worth the possibility to get 17k*5=85,000. Could get 135,000 points in one shot! It's fee free for a year, so try it and cancel just before the years up if it doesn't work and they aren't willing to re-code it for you.
