Geocode database [closed]

Question

Can I download address,city,state,postalcode - latitude/longitude information, that can be loaded to a db for US alone.. Also do comment about their accuracy and coverage..

I suppose all GPS devices do this.. any pointers where I can extract this info??

I tried google maps json api.. and don't like the idea that they rate limit the number of requests per second..

Thanks, Ramya

Edit: What I am looking for is "address , city , state , postalcode, latitude/longitude" in csv or dump.. that I can query locally.. ofcourse.. free of cost (non commercial).

You're looking for something like geocoder.us?

There's also the Virtual Earth API.

Here's a nice list of other geocoder services (thanks to Christopher Klein in the comments ;-)

Edit: I don't think an online service exists that will allow unlimited requests, as this is a security measure to avoid DOS attacks and the likes...
