Your name, permanent address, age and/or an ID is the only thing you need to tell/show the police if they don't have a warrant in my state, I assume the laws are similar in your area. If they want anything else you can tell them to go pack sand. By the way if they are at your front door step, step outside and close your door to talk to them, same if you ever get pulled over. Lots of people accidentally consent to a house/car search by forgetting this one when the police are intimidating them. And if you don't want them to search, (aka "look around") always flat out tell them you do not consent to any searches. Its amazing how many people don't know their own basic rights in this country, trust me folks its very beneficial for you to go do a little research.
