Our database contains multiple methods for making connections between companies and instruments described on sanctions lists, and asset information.
International Securities Identification Numbers (ISINs) are not the native language of the sanctions world: the vast majority of sanctioned companies are private, and do not issue tradeable securities. Instead, companies are more commonly identified by their name, jurisdiction and registration number on sanctions lists. The US Treasury does identify a very small set of ISINs/ticker symbols directly (see: search result, 238 at time of writing).
OpenSanctions expands the government-published sanctions lists with data from other sources. This way, we include securities definitions (and ISINs) from the following sources:
We hope to add more sources to the system in the near future. If you wish to suggest a relevant dataset which we can legally include in OpenSanctions, please get in touch.
To simplify this, we are publishing a CSV table export of all sanctioned companies (using the lists published by the US, EU, UK and Switzerland) with their securities identifiers - LEI, ISINs, RICs and PermIDs inlined for easier analysis.
We're happy to generate a other representations of this data upon request.
