FINRA Rule 4511 — Books and Records Requirements

Overview

FINRA Rule 4511 is the general obligation rule requiring all FINRA member firms to make and preserve books and records as required under FINRA rules, the Securities Exchange Act of 1934, and the rules thereunder (primarily SEC Rules 17a-3 and 17a-4). While SEC rules specify the details of what records must be created and how long they must be kept, Rule 4511 establishes the overarching FINRA obligation and extends it to records required by FINRA-specific rules.

The rule has been at the center of FINRA's enforcement wave against off-channel communications, with billions of dollars in combined regulatory penalties since 2021 for failures to capture and retain business communications conducted through unauthorized platforms.
