The Central Index Key (CIK)

The Central Index Key or CIK is a 10-digit number assigned by the Securities and Exchange Commission (SEC) to identify corporations and individuals who have filed disclosure with the SEC.

It can be used to search for company or fund filings on EDGAR, the Electronic Data-Gathering, Analysis, and Retrieval system of submissions by companies and others who are required by law to file forms with the SEC.

The CIK is often used as part of regulatory reporting, for example, credit rating agencies publish the CIK as one of the unique identifiers associated with their credit ratings.

The CIK identifier is available via the Alacra Authority File and they are also available via our Concordance service.
