WFN QUICK BRIEF · UNDER 1 MIN
The short version
MODE 2 OF 2
What the primary record establishes
FINRA Rule 4511 requires members to keep records under FINRA rules and applicable Exchange Act requirements. Its six-year minimum applies to FINRA books and records for which no retention period is otherwise specified under those rules. FINRA Rule 4511 — General Requirements ↗
What the distinction changes
These provisions illustrate why a single “all records: six years” field is not a complete retention analysis. The first task is classification and identification of every applicable requirement.
What to check before drawing a conclusion
WFN would map each record class to its source rule, retention trigger, format and retrieval process. A stored file that cannot be located when requested creates a different operational problem from a file that was never retained.

Rule 4513 separately requires written customer-complaint records and records of any action taken, with at least four years of preservation. It also addresses keeping the file or making it promptly available at the relevant supervisory office. FINRA Rule 4513 — Records of Written Customer Complaints ↗
02 · WFN EDITORIAL ANALYSIS
What the distinction changes
These provisions illustrate why a single “all records: six years” field is not a complete retention analysis. The first task is classification and identification of every applicable requirement.
Likewise, finding a four-year minimum does not automatically authorize deletion on its anniversary. A record may have other applicable obligations or be needed for an unresolved matter. A minimum is not a universal destruction instruction.
03 · REVIEW POINTS
What to check before drawing a conclusion
WFN would map each record class to its source rule, retention trigger, format and retrieval process. A stored file that cannot be located when requested creates a different operational problem from a file that was never retained.
The cited rules concern FINRA members, not every financial business worldwide. Use the current complete text and applicable requirements for the particular records; this comparison does not determine a firm’s final retention schedule.
