Until recently Chicago didn't have to dial all 10 either. But they added a new area code and now we do. I no longer live in the city, but still have my 773 area code. But those in the outlying areas can dial in their own area code using just 7 digits. I know the TP set the area code, but I just deleted it. I don't know about the TP2, because it is no longer and option. All numbers I dial must be 10.
