I’m looking for a service to get a latitude/longitude dynamically by zip/postal code.
I also need this service to give me an address (city/state/country) by providing an IP Address.
I will be using this service on my website and don’t want to download and maintain a database.
I looked at a few services, some too expensive and some free with a max amount of daily/monthly lookups.
What are some good free services and what are some good paid services (Not too expensive) that allow for a large amount of queries?
I am using asp.net c# with MS SQL Server 2008 or later.
Thanks in advance.
For lat/long: Google and Yahoo allow for several thousand queries per day, at least the last time I used them.
For GeoIP lookup, I can’t say. In the past, I’ve used aggregate data from Google AdWords. This may be true of other advertising networks, or some may give you info per user.
