Series 63 Broker-Dealer and Agent Registration: State Rules You Must Know

State registration requirements are the backbone of the Series 63. Learn who must register as a broker-dealer or agent, the exemptions, and what triggers state jurisdiction.

June 12, 2025

Registration rules under the Uniform Securities Act occupy a substantial portion of the Series 63 exam. They are also among the most tested because they require precision — a broker-dealer that is registered federally is not automatically registered in every state, and an individual who is registered as a broker-dealer agent in one state may need separate registration in another. Getting these rules right on the exam means understanding exactly who must register, with whom, and when exemptions apply.

Who Is a Broker-Dealer Under the USA?

Under the Uniform Securities Act, a broker-dealer is any person (including a firm) engaged in the business of buying or selling securities as an agent for others or as a principal for their own account. The definition is broad by design.

Entities excluded from the broker-dealer definition include:

  • Agents (natural persons acting on behalf of a broker-dealer, not the firm itself)
  • Issuers selling their own securities
  • Banks and trust companies (regulated separately)
  • International banking institutions

The word "business" is significant — an isolated securities transaction does not make someone a broker-dealer. The activity must be regular and for compensation.

State Registration Requirements for Broker-Dealers

A broker-dealer must register in each state where it conducts business. Under the USA, a broker-dealer conducts business in a state if it has:

  • An office in the state, OR
  • More than a de minimis number of clients in the state

Unlike investment advisers, there is no de minimis exemption for broker-dealers based on the number of clients in a state. A broker-dealer with even one solicited client in a state generally must register there unless a specific exemption applies.

Federal registration with FINRA does not substitute for state registration. A FINRA-registered broker-dealer must separately comply with each state's registration requirements. However, FINRA membership firms typically use Form BD filed through CRD (Central Registration Depository) — the same system used for state registrations — which simplifies the administrative process.

Post-Registration Requirements for Broker-Dealers

Once registered, broker-dealers must maintain:

  • Net capital requirements (state-specific minimums, generally tracking SEC Rule 15c3-1)
  • Books and records as required by state and federal rules (typically three years for most records)
  • Surety bond if required by the state Administrator
  • Renewal filings and fees annually

Who Is an Agent?

Under the USA, an agent is a natural person (an individual, not a firm) who represents a broker-dealer or issuer in effecting securities transactions. The agent definition matters because:

  • Agents register in their own name, separately from the firm
  • An agent cannot be registered unless the broker-dealer they represent is also registered in the same state
  • Registration terminates when the agent-firm relationship ends, and the agent must notify the Administrator

Agent Exclusions

Some individuals are not agents even when they work for a broker-dealer:

  • An officer, director, or partner of a broker-dealer is not automatically an agent unless they actually effect securities transactions or receive transaction-based compensation for doing so.
  • Someone who effects transactions in exempt securities only (e.g., a banker transacting only in U.S. government securities) is not considered an agent under the USA.

Agent vs. Investment Adviser Representative

An agent works for a broker-dealer, transacts in securities, and is paid transaction-based compensation (commissions). An investment adviser representative (IAR) works for an investment adviser, provides advice, and is paid fee-based compensation. Some individuals hold both registrations. The Series 63 tests these distinctions frequently in scenario questions.

Registration by Filing for Federal-Covered Securities

Certain securities — those listed on a national exchange (NYSE, Nasdaq), investment company securities, and most securities sold under SEC Regulation D Rule 506 — are federal-covered securities. Under NSMIA (National Securities Markets Improvement Act of 1996), states cannot require full registration for these securities.

However, states may require notice filings and fees for federal-covered securities sold in their state. This is not registration — it is an administrative notice requirement. The Administrator cannot reject a notice filing or impose additional substantive requirements.

The Investment Adviser De Minimis Exemption

The de minimis exemption for investment advisers — not broker-dealers — exempts an IA from state registration in a state where the firm:

  • Has no place of business in the state, AND
  • Has 5 or fewer clients who are residents of that state during the preceding 12-month period

This exemption allows small advisory firms to serve a handful of out-of-state clients without triggering full state registration in every state. It does not apply to broker-dealers or their agents.

Reciprocal Registration

States may enter into reciprocal registration agreements with other states, allowing agents and IAs registered in one state to obtain registration in a reciprocating state with reduced paperwork. The Series 63 does not test the details of specific state agreements, but candidates should know the concept exists and is authorized under the USA.
