I've got the same situation as potatoboy. Never had a physical from anyone at his office, but have gotten plenty of referrals. When I need to get something routine taken care of (cough, cold, etc.) I go to Urgent Care.
I think the OP's just want the PCP info so they can seem like they're one more specialist treating you. Like the PCP is the one who is really taking care of you, and they are just one more health care provider for you.
