What is a CIK number?

A CIK (Central Index Key) is the unique, permanent identifier the U.S. Securities and Exchange Commission assigns to every filer — companies, funds, and individuals — in its EDGAR system. Unlike a stock ticker, a CIK never changes: even if FREEPORT-MCMORAN INC changed its ticker or name, its CIK (0000831259) would stay the same.

That stability is why the CIK is the most reliable way to pull a company's filings programmatically. Every 10-K, 10-Q, 8-K, and Form 4 for FREEPORT-MCMORAN INC is indexed under CIK 0000831259.

CIK vs ticker — what is the difference?

  • Ticker (FCX) — exchange trading symbol; can change or be reused.
  • CIK (0000831259) — SEC filer ID; permanent, one per filer, used across all EDGAR filings.
  • Leading zeros are optional: 0000831259 and 831259 refer to the same filer.
