Results from Phone # on T-Shirt for LLC?

[Alex T.]

I'm currently wholesaling and always looking for new avenues of marketing. I currently have a professional collared shirt for my LLC when I go to appointments. Now I'm deciding to make a T-Shirt with the logo in the front and the back will say "We Buy Houses" in big letters.

The question becomes...Should I add my google voice number on the back of the shirt or not? and if you've done it or know someone that has done it in the past, please share on the experiences.

Any help is greatly appreciated!
