What is a CIK Number?
A Central Index Key (CIK) is a unique identification number assigned by the U.S. Securities and Exchange Commission (SEC) to every entity that files documents through the EDGAR system. CIK numbers are used to identify publicly traded companies, mutual funds, and individual filers in the SEC's database. For example, Apple Inc. has the CIK number 0000320193. Our free CIK lookup tool allows you to search by CIK number to instantly find the associated ticker symbol, company name, exchange, and currency details for any U.S. publicly traded company.
