What is a CIK Number?
A CIK (Central Index Key) is a unique 10-digit identifier assigned by the U.S. Securities and Exchange Commission (SEC) to every company, individual, or entity that files disclosure documents. Unlike ticker symbols, which can change, a CIK number is permanent and never changes throughout a company's lifetime.
CIK numbers are essential for tracking SEC filings in the EDGAR (Electronic Data Gathering, Analysis, and Retrieval) database. They appear in all SEC filings and are used to identify the filer in regulatory documents.
