🇩🇪 WKN German Securities

Wertpapierkennnummer (WKN) is a 6-character identifier used for German securities. Unlike other identifiers, WKN uses only numbers and letters but excludes I, O, and vowels to avoid confusion. Siemens' WKN is 723610, making it easily recognizable in German markets. WKNs are essential for trading on German exchanges like XETRA and Frankfurt Stock Exchange.
