What is a WKN Number

There have been several changes in the WKN definition:

  • WKN were switched from numeric to alphanumeric on 21st July 2003
  • The first 2–4 Letters may show the issuer of the Instrument
  • Many years ago, the WKNs were divided into different number ranges that represented different types of securities (e.g., stocks, warrants, funds, etc.). However, this number range system representing different classes of securities have been abandoned long ago.

WKNs may be obsolete in future, since they may be replaced by International Securities Identification Numbers (ISIN).

ISIN can assist with getting your WKN.
