What if they purchased that key word internationally. If they did that would take up every area code I am going to try pizza later to see if I get the same co.
Agree, Pizza Hut or Dominos would be a good one to use as a trial, they are wide spread and could have a number that you initially are connected to at which point could be redirected to a franchise in your zip code.
I had the same experience when texting Pizza in my area.
I see the biggest potential with larger corporations with this capability already in place.
The info-commercial/shopping channel type could also be an area of focus to utilize the service.
Hope this is being pursued, I'm sure it has been thought of before.
