SEC Form Types

Reference guide for all SEC filing form types and their descriptions

The SEC EDGAR database uses standardised form codes for every type of filing that public companies are required to submit. This reference table explains what each form type means, from the common ones like 10-K (annual report) and 10-Q (quarterly report) to specialised filings like S-1 (IPO registration) and Form 4 (insider trading). Understanding these codes helps you interpret the filings returned by the SEC search tools on this site.
