Central Index Key (CIK)

What is a central index key?

A CIK, central index key, is equivalent to an account number to identify the EDGAR filer. Using the correct CIK is critical for a filing to be associated with the correct EDGAR filer. The CIK is available to the public and cannot be changed. However, when two companies merge, or a company changes their name, the CIK of the surviving/new entity can be associated with the new name by updating the company profile in the EDGAR database, which is a computer system for the receipt, acceptance, review and dissemination of documents submitted in electronic format to the Commission.
