In its capacity as Spain's National Numbering Agency (ANCV: Agencia Nacional de Codificación de Valores), the Comisión Nacional del Mercado de Valores's goal is to identify all Spanish securities and financial instruments with an international code (ISIN : International Securities Identification Number) and to make those codes available to users so that they may be used in systems for settling securities trades and, generally, in all back-office processes.
Whereas the ANCV assigns codes only to Spanish issues, the only ones under its responsibility, it also acts as a point of access to all the securities codes assigned worldwide. To that end, the ANCV is constantly in contact with all the officially-established National Numbering Agencies and exchanges information about issues with them so that Spanish users can have identification information about both domestic and foreign securities.
The ANCV is governed by two items of legislation that date from 2010:
- Comisión Nacional del Mercado de Valores Circular 2/2010, of 28 July, on securities and other instruments of a financial nature that may be numbered and the procedures for numbering.
- Comisión Nacional del Mercado de Valores Technical Standard 1/2010, of 28 July, in connection with its functions of numbering tradeable instruments and other financial instruments, regarding the structure of codes.
The ANCV is a full member of the Association of National Numbering Agencies (ANNA) and is linked to the ANNA Service Bureau, a service created by ANNA to enable National Numbering Agencies and other users to access information on all ISIN codes assigned worldwide. The ANCV participates actively in ANNA's work to harmonise financial instrument numbering practices in the various countries, and it is a member of many of ANNA's working groups.
