CIK Lookup

Dec. 8, 2009

The Central Index Key (CIK) is used on the SEC's computer systems to identify corporations and individual people who have filed disclosure with the SEC.

To find a CIK for a company, fund, or individual type in as much of the company name as you know. For example: "Bank of" would find both "Bank of New York" and "Bank of Boston."


NOTE: The name may be listed differently than expected.
  • the (fictitious) "John Smith" might be "Smith John"
  • "ABC Company" may well be abbreviated as "ABC CO" (with no period at the end)

Search Tips

  • The search will return as many as 100 records that match your keyword(s), but after that it will truncate (cut off) the list. If this happens, it means that you need to be more specific.
    Example:   If you wanted the CIK for "Putnam Global Growth Fund" and found your search truncated when you searched on "Putnam" then you might try searching on "Putnam Global" instead.
  • Not all companies that offer stock for sale must file electronically: for example, certain small companies may be granted exemptions from regular SEC reporting.
  • Additional information about companies that file (such as the SIC code) is also available on the site.
  • You may also search for recently issued CIKs on This page makes public most CIKs the business morning after they are issued. It is in addition to the CIK Lookup at the top of this page, which allows you to find CIKs with associated public filings.
