You may have seen other sites offering free geocoding for exact addresses instead of postal codes and place names.
So what is the point in providing geocoding on postal codes and place names?

The answer is simple. The services working on exact addresses are for the US and some other countries only.
We want to offer geocoding for many more countries, in particular for European countries, and have to use postal codes and place names for our service as there is not enough free data available for a free address based geocoding service.

In short :

US, Cananda => address based free geocoding
most other countries => postal code or place name geocoding.
