FINRA Email Signature Requirements

An email signature sent by a registered representative is communication with the public, so it sits inside FINRA Rule 2210 rather than outside it. In practice that means several things for firms. Titles and designations must be accurate and not imply qualifications the person does not hold, which is why unapproved credential abbreviations in signatures are a recurring examination finding. Any performance claim, guarantee, or promotional banner in a signature is subject to the same fair-and-balanced standard as any other retail communication. The firm's name and the registered broker-dealer relationship generally need to be identifiable, and firms with affiliated registered investment adviser arms commonly require language distinguishing which entity the message comes from. Signatures also fall within the retention obligations that apply to business communications under FINRA Rule 4511 and the SEC's books and records rules, which means the signature content that went out with an email needs to be reproducible later, not just the current version. Centrally managed signatures make this materially easier than per-employee installs, because the firm can prove what was deployed and when.
