# How do I find a company’s CIK?

Canonical: https://sec-api.dev/questions/how-to-find-a-company-cik

> Search the ticker or company name: GET /api/v1/companies?query=TSLA returns the matching ticker, name and ten-digit CIK. On SEC.gov the same lookup is EDGAR company search. Each company page on sec-api.dev, for example /companies/tsla, also states the CIK in its first sentence.

Choose the row whose ticker exactly matches your input rather than the first partial match. An empty result means the current ticker file has no match, not that the entity never filed.
