Why no postal directory appears here
The GeoNames postal download and the GeoNames general Gazetteer are separate products. This country has no rows in the active postal snapshot, so ZipCodeGlobe will not invent or derive a postal code from place coordinates. Gazetteer places remain useful for geographic discovery after they are imported.
