+# Swedish postcodes and their coordinates
+
+This data is a list of address coordinates along with the address postcode. The data has been extracted from the dataset [Belägenhetsadress Nedladdning, vektor](https://geotorget.lantmateriet.se/geodataprodukter/belagenhetsadress-nedladdning-vektor-api) from the APIs of the Swedish mapping, cadastral and land registration authority (*Lantmäteriet).
+All other metadata has been removed.
+
+Thanks to the EU High Value Datasets directive and despite the resistance of Swedish government agencies, this data is now available free of charge, albeit with a few hurdles.
+It can hopefully lead to the end of the monopoly of [Postnummerservice Norden AB](https://postnummerservice.se). Postnord gave exclusive rights to sell postcode data to this private company back in 2005.
