Know Your Customer (KYC)

Overview

Know Your Customer refers to customer-identification and due-diligence measures used by regulated or risk-sensitive organizations. Activities may include verifying identity, beneficial ownership, business purpose, expected activity, geography, source information, and relevant risk indicators.

Exact requirements depend on jurisdiction, activity, customer type, transaction thresholds, and licensing status. KYC is broader than collecting an identity document, and successful verification does not guarantee that future transactions are legitimate or accurately explained.

Organizations should gather proportionate evidence, protect personal data, resolve inconsistencies, rate risk, monitor changes, and refresh information when required. Automated tools support verification but need human escalation, quality control, and accessible correction processes. Retention and deletion rules should reflect both legal duties and privacy risk.

Operators should validate identifiers, timestamps, completeness, provenance, currency or asset units, status semantics, and linkage across onboarding, verification, screening, monitoring, investigation, approval, reporting, and periodic-review events; missing or delayed evidence should create an explicit uncertainty state.

It should state purpose, prerequisites, inputs, steps, thresholds, owners, escalation, evidence location, known limitations, and the exact conditions that require stopping or seeking specialist advice.

Know Your Customer is the process of identifying customers, verifying relevant information, understanding relationships, and applying risk-based ongoing review. KYC establishes and maintains a risk-based customer understanding; it is not a one-time document check or permanent guarantee of legitimacy.

Implementation of Know Your Customer (KYC) should map the process of identifying customers, verifying relevant information, understanding relationships, and applying risk-based ongoing review to the applicable entity, product, customer, transaction, and jurisdictional scope. Evidence for process of identifying customers, verifying relevant information, and understanding relationships should preserve the governing requirement, policy version, control execution, exception decision, owner, and review date. Material changes affecting the Know Your Customer context and process of identifying customers, verifying relevant information, and understanding relationships should trigger reassessment instead of silent reuse of an outdated conclusion.
