FINRA rules strictly prohibit member firms from using the FINRA name or logo in any communication that suggests FINRA endorses or approves of the member firm, its business practices, or any of its products or services. FINRA's role is that of a self-regulatory organization (SRO) responsible for oversight and regulation, not for providing endorsements. Therefore, any statement claiming or implying such an endorsement on a marketing postcard or any other communication is a direct violation of FINRA Rule 2210 and is not permissible under any circumstances.

B: While a principal must approve retail communications, their approval cannot make a prohibited statement permissible. The content itself violates the rule.

C: FINRA does not pre-approve member communications in this manner, and it would never approve a statement that violates its own rules against implying endorsement.

D: The prohibition against implying FINRA endorsement is absolute and applies to all communications, regardless of whether they discuss specific investment products.

1. Financial Industry Regulatory Authority (FINRA). FINRA Rule 2210: Communications with the Public. Section (d)(6)(A) "Use of FINRA's Name or Logo" states: "No member may use the FINRA name or logo in a manner that would suggest that FINRA endorses or approves of the member or any of its products or services." This rule explicitly forbids the action described in the question.

2. Financial Industry Regulatory Authority (FINRA). FINRA Rule 2210: Communications with the Public. Section (d)(1)(A) "Content Standards" states that all member communications must be "based on principles of fair dealing and good faith" and must not "contain any false, exaggerated, unwarranted, promissory or misleading statement or claim." Implying an endorsement is considered misleading.

3. Georgetown University Law Center. Securities Regulation (2022-2023 Course Catalog). Course materials for securities regulation, such as those taught by Professor Donald C. Langevoort, cover the scope of SRO rules, including FINRA Rule 2210, which establishes the standards for broker-dealer communications to prevent misleading statements, including false claims of endorsement by a regulator.
