History and procurement rules
The securities identification number was introduced in 1955. Originally WKNs were divided into two so-called number ranges. You could WKN view directly whether they referred to an annuity ( WKNs 100000-499999 ) or for a share or an " equity-like title " - for example, an equity fund - is ( WKNs 500000-999999 ). This scheme was abolished in March 2000.
On 22 April 2003, the WKN was officially by the twelve-digit ISIN ( International Securities Identification Number) replaced in order to identify and international securities unambiguously. For practical and technical reasons, the WKN but is used in parallel. In a new registration of a security in Germany today (2007) both WKN and ISIN one will be awarded. Generally, there are at any ISIN most a German WKN.
On 21 July 2003 alphanumeric WKNs were admitted (capital letters only, without " O " and "I " to avoid confusion with the numbers 0 and 1). Before, the WKN only numbers. Since 19 January 2004 the WKN contain an abbreviation of the security issuer. The issuer shortcuts are then the first 2-4 letters, completed by a digit.
WM- data service has made the following rules: If the first and second digit of the WKN contains letters, it is an issuer WKN (see examples in the table). From the third point then numbers or letters follow. Alphanumeric WKN however, that are not issuer - WKN, begin with a letter (either an A or an F for normal securities for futures); Second place is for a digit. For example A0A000 was the first ever awarded alphanumeric WKN ( bond of Rhineland Funding Capital Corp., due 2004). Depending on the sort can also be regarded as the first A0AAAA alphanumeric WKN; this is a 2005 ruined Spain bond.
Alphanumeric WKN series A0xxxx were awarded from July 2003 until about October 2009. Since then, the alphanumeric WKN begin A1xxxx (April 2013). In November 2013, the A1Zxxx series was complete; since alphanumeric WKN with a digit in third place ( A10xxx, A11xxx etc. ) have been awarded so far mainly for derivatives ( eg A10750 WKN ISIN CH0223836633 for, it is a call to the Twitter shares of Bank Vontobel ).
Such a series such as A0xxxx can about 1.3 million WKN included ( 24 letters plus 10 digits, high 4 ). From the specified time period ( 2300 days) we can estimate that an average of just under 600 WKN be reassigned per calendar (plus Issuer WKN).
So far, nearly 180 different issuer abbreviation for the WKN were used by AA0000 for products of ABN Amro Bank to ZDWT01 or ZDWT02 for (normal or disabled ) shares ZhongDe (April 2013). The latter is currently also the last valid WKN in the alphabet.
Exceptions to the Rules on Procurement

All other WKN (including issuer WKN ), however, contain at least one digit.
The WKN H1111A (ISIN DE000H1111A6 ) is the only previously assigned Issuer ISIN, in which the abbreviation of the issuer has only one letter. It is a bond due 2007 of Bayer. Hypo-und Vereinsbank.
