Series 63 vs Series 66: Which Exam Do You Need? (2026)

Last updated: April 6, 2026. Based on FINRA and NASAA published exam specifications current in 2026.

Quick Answer: Series 63 vs Series 66

The Series 63 is a state-level securities agent exam. The Series 66 is a combined exam that replaces both the Series 63 and Series 65 in a single test.

Bottom line: If you only need to sell securities, take the Series 63. If you want to sell securities and provide investment advice, take the Series 66 — it saves you from taking both the 63 and 65 separately.

What Each Exam Allows You to Do

Series 63: Securities Sales Only

The Series 63 qualifies you to act as a securities agent in your registered state(s). This means you can:

• Execute securities transactions
• Solicit and sell investment products (stocks, bonds, mutual funds, variable annuities)
• Process client trade orders

You cannot provide personalized investment advice or charge advisory fees with the Series 63 alone.

The Series 63 is most commonly paired with:

• Series 6 — if you sell only mutual funds and variable annuities
• Series 7 — if you sell a broad range of securities

Series 66: Sales + Advisory Combined

The Series 66 qualifies you as both a securities agent and an Investment Adviser Representative (IAR). This means you can do everything the Series 63 allows, plus:

• Provide personalized investment advice for compensation
• Manage client portfolios on a fee basis
• Act in a fiduciary capacity
• Operate under a registered investment adviser (RIA) firm

The Series 66 requires the Series 7 as a co-requisite. You can take the 66 before or after the Series 7, but you must pass both to register. Additionally, the Securities Industry Essentials (SIE) exam is a prerequisite for the Series 7, which means the full path to Series 66 registration is: SIE → Series 7 → Series 66.

When to Take the Series 63

Choose the Series 63 if:

• Your firm only requires agent registration — you will sell securities but not provide advisory services
• You hold or plan to take the Series 6 — the Series 6 does not qualify for the Series 66 co-requisite (only the Series 7 does)
• Your role is transaction-focused — executing trades, processing orders, selling products
• You want the easiest state-level exam — the Series 63 has the highest pass rate (~82%) and shortest study time
• Your firm does not have an RIA or advisory division — you don't need advisory qualifications

Common Series 63 Career Paths

• Registered representative at a brokerage
• Mutual fund sales agent
• Insurance agent selling variable products
• Bank investment representative

When to Take the Series 66

Choose the Series 66 if:

• You want to sell securities AND provide investment advice — the Series 66 is the most efficient path for dual registration
• You have or will get the Series 7 — it is a required co-requisite
• Your firm has both brokerage and advisory businesses — common at wirehouses and hybrid RIA/broker-dealers
• You want to save time and money vs. taking the 63 + 65 separately — one exam instead of two

The Cost-Efficiency Argument

The Series 66 saves you $157 in exam fees and 10–30 hours of study time compared to taking the Series 63 and Series 65 separately. If you already plan to get the Series 7, the Series 66 is almost always the better choice.

Exam Content Comparison

Series 63 Content

The Series 63 covers state securities regulation (often called "blue sky laws"):

Topics include:

• Registration requirements for agents, broker-dealers, and investment advisers
• Exemptions from registration
• Prohibited practices (fraud, market manipulation, churning)
• Administrative enforcement actions
• Client communications and record-keeping

Series 66 Content

The Series 66 covers both state law and investment advisory practice:

The Series 66 is broader because it combines the state law content of the Series 63 with the advisory practice content of the Series 65. You need to understand portfolio theory, client suitability, and fiduciary standards in addition to state regulations.

---

Pass Rates and Difficulty

Why Is the Series 66 Harder?

1. Broader content — it covers state law (like the 63) plus advisory law and practice (like the 65)
2. More questions — 100 scored vs. 60 scored
3. Slightly higher passing threshold — 73% vs. 72%
4. Conceptual depth — investment advisory topics require understanding economic theory, portfolio management, and fiduciary standards, not just memorized rules

That said, if you study for the Series 7 first, you already have a foundation in securities products and regulations that makes the Series 66 content overlap significantly.

The Series 7 Prerequisite Question

A critical difference: the Series 66 requires the Series 7 as a co-requisite. The Series 63 has no FINRA exam prerequisite.

Important Note

If you pass the Series 66 and have a valid Series 7, FINRA's CRD system automatically grants you credit for both the Series 63 and the Series 65. You do not need to take those exams separately.

However, the Series 66 does not maintain validity as a single exam. If you later lose your Series 7 qualification, your Series 63 and Series 65 credits from the 66 may be affected. Check with your compliance department for specifics.

---

NASAA Exam Validity Extension Program (EVEP)

NASAA adopted model rules for an Exam Validity Extension Program that allows eligible individuals to maintain the validity of their Series 63 and Series 65 exams (or Series 66 credits) for up to 5 years by completing annual continuing education requirements. This is similar to FINRA's Maintaining Qualifications Program (MQP).

For Series 66 holders: to extend both the agent and IAR portions, you must enroll for both Series 63 and Series 65 CE credits if applicable. Check whether your state has adopted the EVEP model rules.

State-by-State Considerations

Most states require the Series 63 (or 66) for agent registration, but some states have notable differences:

• Some states allow registered representatives with certain professional designations (CFA, CFP, ChFC, etc.) to waive the Series 65 requirement — but this only waives the advisory portion, not the agent registration portion
• Professional designation waivers do not waive the Series 63 requirement
• A few states may have additional state-specific requirements beyond NASAA exams

Always verify with your state's securities administrator for the exact combination of exams required for your role and registration type.

Decision Flowchart

Use this to determine which exam is right for you:

1. Will you hold a Series 7?

• Yes → Go to Question 2
• No (Series 6 only) → Take the Series 63

2. Will you provide investment advice for compensation?

• Yes → Take the Series 66
• No (sales only) → The Series 63 is sufficient, but consider the Series 66 anyway for career flexibility

3. Does your firm have an advisory (RIA) division?

• Yes → Take the Series 66 (you will likely need advisory qualifications)
• No → The Series 63 works, but the Series 66 keeps future options open
