There are databases with much higher accuracy. I once had a pizza delivery website I had never before used pre-populate the complete address for my location (on a desktop PC with no GPS).

Retailers buy and sell customer data as part of "data cleanup" efforts, that data can be correlated with geo-IP and third-party cookies, etc.
