Why Look Up CIK by Ticker?
When researching a public company, you often start with its stock ticker symbol. But to access SEC filings programmatically or search the EDGAR database efficiently, you need the company's CIK (Central Index Key).
This tool bridges that gap instantly. Enter any ticker symbol and get the company's permanent SEC identifier.

FAQ
How do I find a company's CIK from its ticker?
Enter the stock ticker symbol (like AAPL or TSLA) in the search box above. The tool will return the company's CIK number, full legal name, and a link to all their SEC filings.
What if a ticker has multiple CIKs?
Some tickers may be associated with multiple entities. The tool returns the primary company associated with that ticker. Browse the company's filings to find related entities.
Can I look up delisted stocks?
Yes. Even if a company has been delisted or its ticker has changed, the historical association is preserved. The CIK number remains permanent regardless of listing status.
