Form U4
Form U4 (Uniform Application for Securities Industry Registration) is the form a sponsoring broker-dealer or investment adviser firm files to register an individual with FINRA, the SEC, and state regulators. It is submitted electronically through the Central Registration Depository (CRD) and discloses the registrant's employment history, education, residential history, criminal and regulatory history, and certain financial matters such as judgments and bankruptcies.
A college graduate hired by a broker-dealer as a registered representative cannot start selling securities until the firm files a Form U4 on her behalf through the CRD. The U4 triggers a fingerprint background check, opens her FINRA testing window so she can schedule her qualification exam (such as the Series 6 or Series 7), and feeds her disclosure record into BrokerCheck once she is registered. Note that the SIE itself is open to candidates without firm sponsorship and does not require a U4.
Candidates often think the registered individual files Form U4 directly. They do not. the sponsoring firm files on their behalf. Candidates also confuse Form U4 (the application that opens registration) with Form U5 (the termination notice the firm must file within 30 days when the relationship ends). A separate confusion: the SIE does not require sponsorship or a U4, but the top-off exams (Series 6, 7, 24, and similar) do.
How is Form U4 tested on the exam?
- Identifying who files Form U4 (the sponsoring firm, not the candidate)
- Knowing what Form U4 must disclose (criminal, regulatory, customer complaint, bankruptcy, civil judgment, and lien history)
- Recognizing the 30-day update window for material changes to U4 information
- Distinguishing Form U4 (application) from Form U5 (termination, also due within 30 days)
- Understanding that the U4 opens the FINRA testing window for qualification exams such as the Series 6, 7, and 24

| Description | Limit | Notes |
|---|---|---|
| Update window for material changes | Within 30 days | Material changes include criminal, regulatory, customer complaint, bankruptcy, and civil judgment disclosures |

| Required disclosures on Form U4 | Criminal, regulatory, customer-complaint, bankruptcy, civil judgments, and certain liens | Signed by the registrant under penalty of perjury; false statements are independently actionable |

Practice questions
Test your understanding with the questions below. Pick an answer to reveal the explanation.
A newly hired registered representative candidate is preparing to begin work at a FINRA-member broker-dealer. Which of the following statements about the Form U4 registration process is accurate?
B is correct. The sponsoring broker-dealer or investment adviser firm files Form U4 electronically through the CRD on behalf of the candidate. The candidate signs the form under penalty of perjury and is responsible for the accuracy of the disclosures, but the firm submits the filing. The U4 filing then triggers fingerprinting and opens the candidate's FINRA testing window so the qualification exams can be scheduled.
A is incorrect because the candidate does not file directly. the firm does. C is incorrect because Form U4 is filed before exams are taken so that the testing window can open. D is incorrect because the relationship is the opposite: the SIE is open to unsponsored candidates and does not require a Form U4, while the top-off exams (Series 6, Series 7, Series 24, etc.) do require sponsorship through a U4 filing.
The Series 6 exam tests the mechanics of the registration process. Knowing that the firm files Form U4, that the candidate signs under penalty of perjury, and that the U4 must be on file before top-off exams can be scheduled is essential for any question about onboarding a new representative.
A registered representative is charged with a felony driving-under-the-influence offense over the weekend. Under FINRA rules, by what deadline must Form U4 be updated to reflect this event?
B is correct. Material changes to Form U4 disclosures, including a felony charge, must be reported through an amended U4 within 30 days. Other reportable events that trigger the 30-day update window include customer complaints, civil judgments, bankruptcy filings, and regulatory actions. The disclosure is required at the charge stage. waiting for conviction is not permitted for reportable categories.
A is incorrect because the standard update window for material U4 changes is 30 days, not 10 business days. C is incorrect because 90 days is far too long for a reportable disclosure event. D is incorrect because felony charges (not only convictions) are reportable on Form U4. The registrant and the firm share responsibility for ensuring the amended U4 is filed on time.
The Series 6 exam routinely tests the 30-day update window for material U4 changes. Confusing this with other timeframes (such as the 30-day Form U5 termination deadline or annual ADV updates for advisers) is a common trap. The 30-day update obligation also matters in practice because failure to update is itself a violation that can lead to discipline.
