What is a CIK number?

CIK (Central Index Key) is the SEC's unique identifier for every entity that files with the commission. It's a 10-digit number (zero-padded) used to access all filings, financial data, and company information on EDGAR.

Are foreign companies included?

Yes, any company that issues securities to the U.S. public and is required to report to the SEC (including Foreign Private Issuers) will be listed in EDGAR and have a CIK.

Do I need an API key for SEC lookup?

No, all data is accessed openly via SEC EDGAR endpoints. We only use a custom User-Agent to comply with their fairness policies.
