What is this?
This is project is solving the problem of postalcode lookups. There are many services that do a great job geocoding street or city names. Something that is missing is good postal-code level geocoding. Some industries heavily rely on partial postalcodes to manage their business. Yet, there are no possibilities to look-up these postal codes and geocode them.
What are your data sources?
Currently, the postalcodes and coordinates are based on the geonames.org database.
