Frequently Asked Questions

We try to answer the most common questions about the OpenSanctions project, the dataset it produces and our content policies.

What is OpenSanctions?

OpenSanctions brings together sanctions lists, lists of politically exposed persons (PEPs), and parties excluded from government contracts in different countries. This data is otherwise difficult to query because it is published in a multitude of semi-structured formats across dozens of government websites. OpenSanctions collects the data and converts it into a well-defined and expressive format for easy use and integration into third-party systems.

Does OpenSanctions contain only sanctions lists?

No, we are just bad at naming things. The project includes sanctions lists, lists of politicians, ban lists used in government procurement, lists of known terrorists and other data sources relevant to journalistic research and due diligence. See our inclusion criteria for details.

Who is this for?

OpenSanctions is a resource for journalists and civil society who need to perform due diligence-style tasks (e.g. searching for persons of interest in a leak or open dataset), and for companies in the fintech/regtech space that need to perform basic know-your-customer checks.

OpenSanctions is an open project, anyone is invited to use the datasets, the code base used to generate it, or to contribute additional information.

Where does the data come from?

Our preferred sources are official datasets published by governments and other authorities all over the world; including commonly used sanctions and ban lists. In the future, we hope to also include information from media reporting, Wikidata and Wikipedia and litigation.

How frequently is OpenSanctions updated?

Most data sources are updated daily and published in the early morning (CET). You can inspect the public data pipeline and see a list of any errors or warnings each dataset has generated.

For data sources that require screen scraping rather than publishing structured data, a HTTP response cache with a maximum age of ten days is used to avoid running into rate limiting errors.

Is there an API for matching entity lists against OpenSanctions?

We're focussed on offering plain data downloads. Running an API would be expensive, and raise a set of legal and administrative issues. It would also make us a competitor to many of the organisations that we hope can become OpenSanctions users.

If you provide an API that allows matching against OpenSanctions data, we’d love to hear about it and link to it from this site.

In the future, we might consider a project to provide a matching API server as free software, e.g. as a Docker container with the latest OpenSanctions data bundled inside it that users can run on their own premises.

Can I contribute a new data source?

Yes, we’re open to contributions. We're particularly keen to add sources that include information from criminal cases, and family and associates of politically exposed persons. Learn more about contributing data...

Can I use this data for commercial purposes?

Please be our guest. If you use OpenSanctions for your business, please consider becoming a sponsor to guarantee the continued development and operation of the project.

What is a politically exposed person (PEP)?

Politically exposed persons (PEP) is a term from the banking industry to describe individuals who have been entrusted with a prominent public function. This might include a members of cabinets, parliaments, senior public servants or people that run state-owned companies.

The concept is important because PEPs and members of their family should be the subject of enhanced public scrutiny. This is also mandated by financial crime laws in many countries.

OpenSanctions includes a PEPs collection that combines lists of politicians from multiple origins.

What is a collection?

A collection is a bundle of entities (people, companies, etc.) from multiple data sources. These sources might have a similar topical focus (e.g. international sanctions, or procurement bans) that sets the theme of the collection. Data users usually pick a relevant collection when integrating data into an upstream application.

OpenSanctions is an effort to acquire relevant data from a large array of online sources and to bundle it into more useful, synthetic entity lists for our users. To provide transparency and choice, we also re-publish the entities from each data source separately.

Please note that entities from different data sources are not yet de-duplicated in collections. If two source lists mention the same individual or company, they will be included twice. De-duplication will become available in Q4/2021.

Will you delete data about me?

OpenSanctions, by its nature, includes data about many individuals - particularly those mentioned on international sanctions lists, those holding a public office, and those included in published criminal databases. We believe that processing and publishing this data is in the public interest.

If information about you is included in this site and you would like to see it removed, please contact the initial publisher of the information, e.g. the authority publishing the sanctions list, the law enforcement body etc. to discuss the removal of your information.

Once that removal has been processed, please allow for up to one week for the information to disappear from OpenSanctions.
