If you need a one off solution  you can try  https   addresstolatlong com   I ve used it for a long time and it has worked pretty well for me

User · Answer

Thought I would add one more to the list   Texas A amp M has a pretty decently priced service here  http   geoservices tamu edu Services Geocode   A good option if you have a pretty large set of addresses to geocode and don t want to pat 10k to Google or Microsoft   We still ended up using the returned data in a Google Map

Nothing much new to add  but I have had a lot of real-world experience in GIS and geocoding from a previous job  Here is what I remember   If it is a  every once in a while  need in your application  I would definitely recommend the Google or Yahoo Geocoding APIs  but be careful to read their licensing terms   I know that the Google Maps API in general is easy to license for even commercial web pages  but can t be used in a pay-to-access situation  In other words you can use it to advertise or provide a service that drives ad revenue  but you can t charge people to acess your site or even put it behind a password system   Despite these restrictions  they are both excellent choices because they frequently update their street databases  Most of the free backend tools and libraries use Census and TIGER road data that is updated infrequently  so you are less likely to successfully geocode addresses in rapidly growing areas or new subdivisions   Most of the services also restrict the number of geocoding queries you can make per day  so it s OK to look up addresses of  say  new customers who get added to your database  but if you run a batch job that feeds thousands of addresses from your database into the geocoder  you re going to get shutoff   I don t think this one has been mentioned yet  but ESRI has ArcWeb web services that include geocoding  although they aren t very cheap  Last time I used them it cost around 1 5cents per lookup  but you had to prepay a certain amount to get started  Again the major advantage is that the road data they use is kept up to date in a timely manner and you can use the data in commercial situations that Google doesn t allow  The ArcWeb service will also serve up high-resolution satellite and aerial photos a la Google Maps  again priced per request   If you want to roll your own or have access to much more accurate data  you can purchase subscriptions to GIS data from companies like TeleAtlas  but that ain t cheap  You can buy only a state or county worth of data if your needs are extremely local  There are several tiers of data - GIS features only  GIS plus detailed streets  all that plus geocode data  all of that plus traffic flow direction speed limits for routing  Of course  the price goes up as you go up the tiers   Finally  the Wikipedia article on Geocoding has some good information on the algorithms and techniques  Even if you aren t doing it in your own code  it s useful to know what kind of errors and accuracy you can expect from various kinds of data sources

Having rolled my own solution for this before  I can whole heartedly recommend the Geo  Coder  US Perl module for this  Just download all the census data and use the included importer to create the Berkeley DB for your country and point the Perl script at it  Use the module s built in address parsing  and there you have it  An offline geocoding system
