Wertpapierkennnummer

[1]The Wertpapierkennnummer, (WKN, WPKN, WPK or simply Wert), is a German securities identification code. It is composed of six digits or capital letters (excluding I and O), and no check digit.

For other subjects, see WKN (disambiguation).

Changes in format

There have been several changes in the WKN definition:

  • WKN were switched from numeric to alphanumeric on 21 July 2003[2]
  • The first 2–4 Letters may show the issuer of the Instrument[3]
  • 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 has been abandoned long ago.

The WKNs and DE-ISINs are provided by WM-Datenservice.

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

Spelling and meaning

Like most very long German words, Wertpapierkennnummer is a compound word: Wert-Papier-Kenn-Nummer, if translated literally, means value–paper–to know–number (Wertpapier = financial security; Kennnummer = identity number).

Before the German spelling reform of 1996 the correct spelling was Wertpapierkennummer with only two consecutive n’s, since the orthography rules allowed the same consonant three times in a row only under special circumstances. Since the reform, the spelling has been Wertpapierkennnummer with three consecutive n’s.

gollark: Also, the 100 shards/week cap.

gollark: Stupid CB egg cooldown...
