Free Batch Geocoder

This free web app is a batch geocoder retrieving latitude and longitude of multiple adresses, using OSM.

However, It will only geocode if your input fully matches underlying OSM database entries. OSM does not provide "spelling correction" like Google Maps. So, omitting city may increase the number of geocoded records (if you are not sure how it is spelled due to foreign characters).

Alternatives

Download geocoding files from www.geonames.org, import data into Excel, VLOOKUP latitudes/longitudes.
Use Batch Geocoder: extremely fast, including "spelling correction" (Google Maps API based, fee applicable).

YOUR INPUT - semicolon separated or tab separated
Record_number;City;Postal_code;Street_name_and_number;Country*

* You may specify country and postal code only, or leave out street number. But the more correct address data provided, the more accurate the geocodes will be.
