What Is Form BD?

Form BD is the uniform application for broker-dealer registration. A firm uses it to register as a broker-dealer with the SEC, self-regulatory organizations such as FINRA, and state securities regulators where required.

The form collects core information about the firm, its control persons, business activities, affiliations, branch offices, disciplinary history, and regulatory status. It is part of the gatekeeping system for firms that buy and sell securities for customers or for their own account as broker-dealers.

Key Takeaways

  • Form BD is used for broker-dealer registration.
  • The filing supports SEC, SRO, and state regulator review.
  • It includes business, ownership, control, branch, and disciplinary information.
  • Registration does not mean regulators endorse the firm or guarantee customer outcomes.

How Form BD Works

A broker-dealer applicant files Form BD electronically through the Central Registration Depository system. The filing is reviewed alongside other registration requirements, including membership with appropriate self-regulatory organizations and applicable state registrations.

After registration, broker-dealers must keep information current. Changes to business lines, ownership, control persons, or other reportable items may require amendments. If a broker-dealer withdraws, it generally uses Form BDW rather than simply disappearing from the registration system.

How Investors Can Use the Information

Investors do not usually read Form BD the way they might read a disclosure brochure from an investment adviser. Instead, the information feeds registration systems and public records that help investors verify whether a brokerage firm is registered and whether it has reportable disclosures.

Form BD is especially useful as background for understanding a broker-dealer's regulatory footprint. It does not, by itself, explain whether a specific account, product, recommendation, or fee arrangement is appropriate.

The practical use is verification. A customer can pair broker-dealer registration records with BrokerCheck, account agreements, fee schedules, and written disclosures to understand who they are dealing with and what business the firm is authorized to conduct before opening or moving an account.

The Bottom Line

Form BD is the core broker-dealer registration application. It helps regulators and public databases identify who a broker-dealer is, what business it conducts, where it is registered, and whether it has disclosures that customers should review.
