Improved Postalcode Coverage in France and Spain

We’ve added tens of thousands of postalcodes from Eurostat, filling in coverage gaps in France and Spain.

One of the many hats we wear as maintainers of a geocoding service is that of data hunter. We scour the internet and open data portals worldwide to look for just the right datasets to add to our collection. High quality, clear licensing, and fitting perfectly into a gap in our existing coverage.

The best datasets bring in data that’s consistent, but also cover a wide area. That’s why we’re pleased to now include postalcodes in Spain and France from Eurostat. These postalcodes will fill in a few gaps in our existing, but not quite perfect, French coverage. In Spain, we offered no postalcode coverage at all, and we now have close to, if not exactly, 100% coverage.

Postalcodes are a bit of an oddity in location data: they often don’t have an officially defined location at all, and pitfalls abound when using them directly for geospatial analysis. Nonetheless, they’re an extremely important shorthand for a rough geographic area, so we know they’ll be useful to many of you using our service.

Eurostat, being the statistics department of the entire European Union, publishes postalcode data for many more countries, not just France and Spain. We’ll be evaluating and no doubt adding more soon. If you’re looking for postalcodes for one country in particular, please shoot us a (virtual) letter to let us know, no postage required.
