The Series 7 and Series 66 are complements, not alternatives. Series 7 lets you sell securities on commission as a broker-dealer rep. Series 66 lets you charge advisory fees as an Investment Adviser Representative and registers you with the states. Most wirehouse reps at Merrill Lynch, Morgan Stanley, Wells Fargo Advisors, and Edward Jones hold both. Take the Series 7 first. The Series 66 stacks on top.
What’s the difference between Series 7 and Series 66?
The Series 7 and Series 66 sit on opposite sides of the regulatory split that defines retail wealth management. One is a federal product-and-sales exam; the other is a state-law-plus-advice exam. Together they cover the dual registration most modern wirehouse reps need.
- Series 7 is the FINRA General Securities Representative exam. It qualifies you to sell virtually every retail security on commission: stocks, bonds, options, mutual funds, ETFs, variable annuities, 529 plans, UITs, REITs, municipal bonds, and limited partnerships. It pairs with the SIE co-requisite.
- Series 66 is a NASAA exam (administered by FINRA on behalf of the states) that combines the Series 63 state-law content with the Series 65 investment-adviser content. When paired with the Series 7, it qualifies you for both state securities-agent registration and IAR registration.
The Series 7 makes you a broker-dealer rep. The Series 66 turns you into a dual-registered rep who can act as both a broker and an adviser. Most full-service firms expect both.
Series 7 = what you can sell. Series 66 = where you can sell it (state registration) plus how you can charge for it (fees, not just commissions). The two exams cover almost nothing in common.
What can you sell with Series 7 vs Series 66?
- Individual stocks (common and preferred)
- Corporate, municipal, and Treasury bonds
- Options and derivatives
- [Mutual funds](/glossary/mutual-fund/) and ETFs
- [Variable annuities](/glossary/variable-annuity/) and variable life
- 529 plans, [UITs](/glossary/uit/), REITs, limited partnerships
- IAR registration (charge advisory fees, not just commissions)
- State agent registration in all 50 states
- Ability to manage discretionary fee-based accounts
- Authority to advise on portfolio construction for a fee
- Registration to open and operate at a hybrid BD plus RIA firm
- Coverage of Uniform Securities Act prohibited practices
The Series 7 alone makes you a commission-based broker. The Series 66 adds the legal authority to charge fees for advice and to register with the states where your clients live. Without the Series 66 (or its component exams), your wirehouse cannot put you on fee-based accounts and most states will not let you transact with retail clients.
Do you need both Series 7 and Series 66?
If you work at a wirehouse or full-service broker-dealer that offers fee-based advisory accounts, yes. The list of firms expecting this stack includes Merrill Lynch, Morgan Stanley, Wells Fargo Advisors, Edward Jones, JPMorgan, Goldman Sachs, Fidelity, and Schwab. Most independent broker-dealers (LPL, Raymond James, Cetera) also expect both.
The exceptions are narrow. Reps focused exclusively on commission-based transactional business (some older wirehouse tenured reps, certain institutional desks, fund wholesalers) may carry only the Series 7 plus an older Series 63. Reps at insurance carriers or bank wealth desks that do not offer fee-based advisory may carry the Series 6 plus Series 63 instead. But for new hires at modern full-service firms, the default stack is SIE plus Series 7 plus Series 66.
Twenty years ago the wirehouse stack was Series 7 plus Series 63. The shift to fee-based advisory accounts in the 2010s pushed firms toward the Series 66 because it bundles the IAR registration that fee-based business requires. New reps almost never start with a Series 63 today unless their firm explicitly does not offer fee-based work.
Series 7 vs Series 66: difficulty comparison
The Series 7 is harder by most measures. The exam-difficulty math:
| Metric | Series 7 | Series 66 |
|---|---|---|
| Scored questions | 125 | 100 |
| Time limit | 225 minutes | 150 minutes |
| Passing score | 72% | 73% |
| Hardest sections | Options, municipal bonds, customer accounts | Economics, security analysis, ethics |
| Typical prep hours | 80 to 120 | 50 to 75 |
| Typical prep weeks | 6 to 10 | 4 to 6 |
The Series 7 is bigger, longer, and denser. Options pricing, municipal bond math, and the volume of customer-account scenarios catch most unprepared candidates. The Series 66 looks shorter but the calculation work in security analysis (ratios, Modern Portfolio Theory, time value of money) is real and the ethics section tests applied judgment, not just rote memorization.
Series 66 candidates frequently fail because they treated the ethics or fiduciary section as memorization. It is not. The Series 66 ethics questions test how you apply fiduciary duty to client scenarios, which is harder than the FINRA conduct rules on the Series 7.
Series 7 vs Series 66: cost and time
The combined cost stack is straightforward.
| Cost | Amount |
|---|---|
| SIE exam fee (FINRA) | $80 |
| Series 7 exam fee (FINRA) | $395 |
| Series 66 exam fee (NASAA) | $177 |
| Combined exam fee total | $652 |
Most wirehouses reimburse all three exam fees plus prep materials for new hires. Self-funded candidates pay out of pocket. Prep providers range from $99 (CertFuel-style adaptive) to $599 (Kaplan or STC premium packages) for full Series 7 plus Series 66 bundles. CertFuel covers the SIE for free, which removes the SIE side of the prep stack for most candidates.
Combined study time: 10 to 16 weeks at 12 to 15 hours per week (130 to 195 hours total). Working professionals often spread it to 14 to 18 weeks. Most firms expect both exams cleared within 6 to 9 months of hire.
Free SIE Prep, Wirehouse Stack Optional
The SIE is the gateway to Series 7 and the standard wirehouse on-ramp. Free SIE prep with adaptive quizzes and FSRS flashcards. No sponsorship needed.
Choose Your PathWhich should you take first?
Take the Series 7 first. There are three reasons this is almost universally the right sequence:
-
The Series 66 needs the Series 7 to activate IAR registration. You can sit for the Series 66 first if you want, but the IAR side of the registration does not become effective until you also pass the Series 7. Sequencing Series 7 first avoids carrying a Series 66 pass that does nothing until your Series 7 result clears.
-
Sponsoring firms onboard Series 7 first. Compliance teams at wirehouses and full-service broker-dealers typically file Form U4 for the Series 7 within the first weeks of hire and add the Series 66 after the Series 7 result is in. This is so consistent across firms that fighting it usually means waiting on your compliance team anyway.
-
Series 7 content makes Series 66 easier. The Series 7 covers individual securities, packaged products, customer accounts, and FINRA conduct rules. A lot of that foundation reappears in the Series 66 in different framing (state law angle, fiduciary angle, investment-adviser angle). Taking the Series 7 first means you arrive at Series 66 prep with most of the product knowledge already locked in.
Most wirehouse trainees pass the SIE, then the Series 7 within 90 days of hire, then the Series 66 within 30 days of the Series 7. End-to-end timeline from start of Series 7 prep to dual registration: about 4 to 6 months.
