Get offer from other insurance – what do I need ?

Hello, I get Monday n new car and would like to compare some insurances this time. I have been driving for 7 years. My cars have only been insured as a second car on my father until now, but I was registered as a driver. If I now go to another insurance company, what do I have to take with me or does he need nothing at all and makes me an individual offer ? Because I have seen so no own SFK. Thanks already
