Started from November 1st all of a persons' first names was synchronized to SUKAT (before only the first first name was synchronized). Ladok gets its data from The Swedish Population Register (Skatteverket). If you have more than one first name registered and don't want all of them shown in SUKAT you can register a given name (tilltalsnamn) with Skatteverket. If you do so only your chosen given name "tilltalsnamn" will end up in Ladok and consequently in SUKAT. It's very easy to make this change, it takes a couple of minutes and is free of charge.
