What is a CIK (Central Index Key)?
A CIK is the unique number the U.S. Securities and Exchange Commission assigns to every entity that files with it. It is the backbone of the EDGAR system: every 10-K, 10-Q, 8-K, and Form 4 is indexed by the filer's CIK. Unlike a ticker, a CIK is permanent — it survives ticker changes, rebrands, and mergers — which makes it the most reliable key for pulling a company's filings.
CIK lookup FAQ
What is a CIK number?
A CIK (Central Index Key) is the unique, permanent identifier the SEC assigns to every filer — companies, funds, and individuals — in its EDGAR system. It never changes, even if a company changes its ticker or name.
How do I find a company's CIK?
Search the company on SEC EDGAR, or pick a company from the directory below — each links to a page showing its CIK instantly. You can also visit /cik/[ticker] directly, e.g. /cik/aapl.
Is a CIK the same as a ticker or CUSIP?
No. A ticker is an exchange trading symbol and a CUSIP identifies a specific security. A CIK identifies the SEC filer. One company has exactly one CIK but may have several tickers or CUSIPs over time.
