Picking the right transaction code is the first decision in every Form 4. The guidance for it sits in three places at once: the SEC’s General Instructions, the EDGAR schema, and whatever a practitioner remembers from the last unusual filing.
We have pulled it into one place. Form 4 Transaction Codes ranks every code by how often it was actually filed in 2025. Each of the common codes then has its own page: what the code reports, when to use it, the columns EDGAR expects, and what a footnote on that code typically has to explain. The rarely used codes share a single page.
