## What it does

This skill covers what has to be gathered before an account opens and how the customer profile gets maintained afterwards. It carries FINRA Rule 2090, the CIP requirements (31 CFR 1023.220) and FinCEN's CDD Rule (31 CFR 1010.230). Ask about identity verification, beneficial ownership collection for entity accounts, enhanced due diligence for PEPs or high-risk customers, the initial risk rating, or KYC refresh triggers, and the agent answers from those rules.

Documentary and non-documentary verification are treated separately. The first relies on an unexpired government photo ID or formation documents; the second on credit bureau checks, public database searches and financial statements. Non-documentary methods are the fallback when the customer never appears in person or the paperwork raises doubt.

One thing to watch: the regulatory status inside the skill is pinned to June 2026, and the text itself tells you to check effective dates, dollar thresholds and pending rulemakings against current SEC, FINRA and FinCEN sources before advising. So verify the numbers yourself rather than trusting the file. For transaction monitoring, SAR filing and risk re-rating driven by surveillance, the author points to a separate anti-money-laundering skill.

name: know-your-customer
description: "Guide customer onboarding identification, due diligence, and profile maintenance under FINRA Rule 2090, the CIP rules, and the FinCEN CDD Rule. Use when the user asks about onboarding identity verification, beneficial ownership collection for entity accounts, enhanced due diligence for PEPs or high-risk customers at account opening, assigning the initial customer risk rating, KYC refresh triggers, or documentary vs non-documentary verification. Also trigger when users mention 'account opening requirements', 'who is the beneficial owner', 'new client identity check', 'how often to update KYC', 'essential facts for the account', 'foreign customer onboarding', or ask what information must be gathered before opening an account. (For ongoing transaction monitoring, SAR filing, and surveillance-driven risk re-rating, use anti-money-laundering.)"

# Know Your Customer

Regulatory status current as of June 2026 — verify effective dates, dollar thresholds, and pending rulemakings against current SEC/FINRA/FinCEN sources before advising.

## Core Concepts

### FINRA Rule 2090 — Know Your Customer
Every FINRA member must use reasonable diligence, with regard to the opening and maintenance of every account, to know and retain the essential facts concerning every customer and concerning the authority of each person acting on behalf of the customer. "Essential facts" are those required to: (a) effectively service the account, (b) act in accordance with any special handling instructions, (c) understand the authority of each person acting on behalf of the customer, and (d) comply with applicable laws, regulations, and rules.

### Customer Identification Program (CIP)
Required under USA PATRIOT Act Section 326 and implementing regulations. The broker-dealer CIP rule is **31 CFR 1023.220**; the bank CIP rule is 31 CFR 1020.220. (SEC Rule 17a-8 separately requires broker-dealers to comply with BSA recordkeeping and reporting.) The CIP must include:

- **Identity verification** for each customer opening an account: name, date of birth (for individuals), address, and identification number (SSN for US persons; passport number/country or other government ID for non-US persons)
```
