Look up an Address:Enter a US address or intersection, e.g. 1600 Pennsylvania Ave, Washington, DC. For best results please use a comma between the street and the city, and add the zip code if possible. Free lookups are throttled by your IP address to one request every 15 seconds.

How can I help?
You can make improvements to the source code and send patches for inclusion in future releases. You can also donate via PayPal to help defray the cost of developing and hosting this free public service. Any amount is appreciated!
Oct 15, 2012 Server load this morning was through the roof. Checking the log files it is largely because of people using the free service, but not respecting the 15 second throttle. Please, if you are going to use the free service please try to space your requests out a bit. Thank you!
Recent News and Notes
July 27, 2012 Service outage and restoral. We are so sorry but Geocoder.us was down. We appear to have restored all functionality. Please let us know if there are continuing issues. We are sorry for this!
If you are dependent on geocoding for mission critical services than you might consider having us install an instance of the geocoder system on your own server. Depending on the customization and support required we can do this for around $2,500.
Feb 2, 2012We are working to expand the geocoder.us product offerings. Please Email email@example.com if you have product/service requests. Additional data? Mapping services? Census data? Proximity/nearest neighbor? Spatial database/consulting services? Throw us your ideas!
Oct 26, 2011Please don't be a creep. Pretty please. If you are using the free service please don't make more than one request every 15 seconds. The throttle code will spit out a 503 errror, so you won't get your address, but it appears that dealing with all those requests is slowing the server for everyone.
Sept 2, 2011 The site has not been updated for a while because frankly for the most part 'it just works.' Behind the scenes Geocoder.us now has three people working on it, Jay Longson and Molly Gibson have taken over most operations, and Rich Gibson (who has been primarily running it for years now) is available to them as needed. Schuyler Erle is doing awesome work all over the place, but he is still available when the questions get really hard :-)
September 16, 2010 I've created a new Geocoder.us blog, please help me put the common questions in the blog. Also, I (Rich) have been out of town, and backlogged with fires to fight. I am working to catch up to my backlog. If you have an important issue please email me again, thank you for your patience and support!
April 8, 2010 Geocoder.us is run primarily as a public service by Rich Gibson and Schuyler Erle.
Schuyler Erle, creator of Geocoder.us, spent time in Haiti doing mapping work in support of the relief efforts. Schuyler, John Crowley, and Jeffrey Johnson spoke about Crisis Mapping at the Where 2.0 conference on April 2nd, 2010. Watch their talk here.
The key quote to me (Rich) is 'Open Street Map saved lives in Haiti.'
