GeoNames webservice and data download

GeoNames Data Access

You can either download a daily database export or use our webservices to directly access our data.
See the feature codes list for explanation on the feature codes used by GeoNames.

GeoNames is using ISO-3166 alpha2 country codes.

In case of questions or troubles you might find help in our forum.

GeoNames is mainly using REST webservices.
Important:
* Don't forget to url encode string parameters containing special characters or spaces. (Faq entry on url encoding)
* Use the JSON services if you want to use GeoNames from javascript, as most browsers do not allow to call xml services from ANOTHER server.
