I just have two accounts ;one for me and one for my aunt who lives in Arkansas. They're both in my name and I didn't get any discount because I already had the receiver so I just installed it and turned it on , on my second account. I pay both bills and my Aunt sends me the money once a month. Well she sends me 15.00 and I pay the 1.94 . She only has locals and no base package. She doesn't want to deal with a sat company , so I do it.
IF you want your dad to have the install in his name then they will require his social security number to check his credit . You can pay for it no problem; just set up his billing address as your own and use your credit card . You might see if they will let you do an install on the digital home advantage plan. Then you could just lease your dad's receiver at your dad's address and you keep it in your name all the way . Just list the service address as your dad's and your billing address as your own.
