ISIN Issuance and Acceptance

ISIN Issuance

Clearstream, as National Numbering Agency for Luxembourg, issues ISIN, CFI and FISN codes for any Luxembourg-domiciled securities, according to ANNA guidelines and more specifically for Luxembourg-incorporated investment funds and companies.

ISIN (International Securities Identification Number): a twelve digit alphanumeric code which uniquely identifies a specific security. (ISO 6166).

CFI Code: Securities description code promoted by the Association of National Numbering Agencies (ANNA) which describes the characteristics defined when the concerned financial instrument is issued and remains unchanged during the whole life of the security (ISO 10962:2015).

FISN (The Financial Instrument Short Name) code has been developed to provide a consistent and uniform approach to standardise short descriptions for financial instruments (ISO 18774:2015).

Any appointed fund agent (as documented in the relevant prospectus), typically the transfer agent, registrar, fund manager or administrator can request the issuance of an ISIN code from Clearstream Banking Luxembourg (CBL).

Such a request should be sent by email to fundacceptance@clearstream.com accompanied by the following documentation:

  • Fund prospectus (and supplements if any);
    • Final prospectus for regulated funds: stamped by the Luxembourg regulator Commission de Surveillance du Secteur Financier (CSSF);
    • Final prospectus for unregulated funds: a final, non-editable, version free of editing marks and placeholders;
    • Draft prospectus if the CSSF approval for the new/updated prospectus in still pending;
  • Setup template with all mandatory fields completed (template available for download at the bottom of this page).

LU ISIN issuance requests missing any of the above mentioned information will be refused and would have to be resubmitted with all required information.

If in addition to the LU ISIN a CFI or an FISN is required this needs to be specifically mentioned in the email request.
