There is some ZIP-code information available but it does not fit the Index criteria.

Latvia Post has a ZIP-code index page ("Pasta indeksu grāmata") containing a number of XLS files in unstructured / semi-structured form. It shows the relation between locations (towns, streets, etc.) and relevant ZIP-codes but does not contain lat/long coordinates nor is there another service where one could resolve ZIP-codes to geo-coordinates.

Note: the URL of the ZIP-code index page had changed since we last checked it in July 2014.

Reviewer comments

I did see that the map centre has part of the data - lon/lan data formats. Therefore data exist, but not in one uniform datasets, but two. I changed the data accordingly.
