ISO Standards at a Glance

We Maintain and Update the ISO Currency Codes

Currency Codes of the International Standard ISO 4217 are important in any information technology application related to trade, commerce and banking, as well as in the public sector. 

At SIX, we continually update these codes to reflect all global economic and political changes. We maintain and update this code, ensuring that you always have access to the latest and most accurate data.

SIX is the official Maintenance Agency of these currency codes under ISO 4217 and as such the only recognized, authoritative source on currency code designations. 

SIX provides these currency code service on behalf of the International Organization for Standardization (ISO) and its Swiss member SNV (Swiss Association for Standardization). We maintain the code lists, update them and make them available online and free of charge.

We Maintain and Update the CFI Code

The ISO 10962 Classification of Financial Instruments (CFI) is a globally recognized standard for describing all financial instruments, including traditional securities, derivatives, and innovative products.

The six-letter code describes the structure and function of each financial instrument in a consistent way. The code defines when a financial or referential instrument is issued and remains unchanged during its entire life. However, events such as the changing of voting rights or ownership restrictions decided at a stockholders' meeting can cause a CFI code to change.

As the maintenance agency for the CFI code, SIX manages updates and enhancements. We publish these updates in various formats like spreadsheets, CSV, JSON-LD, and TTL.
