Which banks or credit card companies only pull credit worthiness from Transunion in Texas?:)

Call transunion and ask them. Really no way to know this. If you are trying to find out something that relates to your credit or if you have been denied credit recently you should go get your free report from each of the three services. Transunion, Equifax, Experian. Directions on each site or call them. It is the law your are entitled to one free reoprt every 12 months. Not sure why you would be asking this question though need more details.
