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 United Airlines Holdings, Inc. changed its ticker or name, its CIK (0000100517) 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 United Airlines Holdings, Inc. is indexed under CIK 0000100517.

CIK vs ticker — what is the difference?

  • Ticker (UAL) — exchange trading symbol; can change or be reused.
  • CIK (0000100517) — SEC filer ID; permanent, one per filer, used across all EDGAR filings.
  • Leading zeros are optional: 0000100517 and 100517 refer to the same filer.
