ISIN (International Securities Identification Number) is a unique code, a mandatory attribute of the security that distinctly identifies the security. 

The ISINs issued by KELER and the basic securities data can be queried on the website of KELER.


Service details

Each securities series (including physical and dematerialized series) is distinctly identified with an ISIN. The ISIN (International Securities Identification Number) is a 12-character alpha-numerical code that serves to uniformly identify securities series or other exchange traded products. The first two characters of ISINs issued by KELER are “HU”.

The securities in the same series have identical ISIN. Based on the ISIN Order the issuer is required to apply for ISIN in the following cases:

  • issue of new securities series,
  • if there is a change related to the existing (earlier identified) securities series in terms of
    • format of production (e.g. physical → dematerialized)
    • nominal value or currency
    • related rights and obligations
  • if the securities within the same securities series, issued at different points in time, represent non-identical rights temporarily (e.g. fraction dividend)   or
  • in the case of issuing securities in the same series where already listed securities exist and the securities issued later are listed at the same exchange at a time other than the time of issue.

 There is no need to apply for a new ISIN:

  • if there is a change in quantity (increase or decrease) of the securities in the series that already has ISIN,
  • if there is a change in the data of the issuer (e.g. issuer name, registered office, trade register number, etc.) of the series that already has ISIN.

KELER issues the ISIN at the request of the issuer. In line with the ISIN Order the ISIN can be applied for as follows:

  1. electronically at the interface operated by KELER (eISIN) or
