KYC (Know Your Customer) is the process by which a company verifies the identity of its customers before establishing a business relationship. It is an essential practice in banking, fintech, insurance, crypto, and any regulated sector that must prevent money laundering, terrorist financing, and fraud.
What is KYC?
KYC is the set of procedures and controls that allow a company to know who it is doing business with. It involves collecting information about the person — name, identity document, date of birth, address — and verifying that this information is authentic and corresponds to the person claiming to be.
In regulatory terms, KYC is the first line of defense within an Anti-Money Laundering and Counter-Terrorist Financing (AML/CFT) program. Without solid KYC, it is not possible to apply sanctions screening, transaction monitoring, or risk management effectively.
Why it matters
Regulatory and reputational risk
Regulators around the world — FATF, FinCEN in the US, FCA in the UK, AMF in France — require documented KYC procedures. Fines for non-compliance can reach millions of dollars. Beyond money, a KYC failure can link a company to organized crime networks, with reputational consequences that are difficult to reverse.
Trust and portfolio quality
Good KYC does not only protect against risks. It also improves the quality of the customer base, reduces fraud in account opening, and allows customers to be segmented by risk level to offer appropriate products.
Market access enabler
To operate in certain markets — institutional, correspondent banking, international payments — demonstrating a robust KYC program is a prerequisite. It is the credential that opens doors.
The stages of modern KYC
1. Identity verification
The process begins with the collection and validation of documents: passport, national ID, or driver’s license. Modern tools perform OCR on the document, verify authenticity (MRZ, NFC chips, holograms), and compare the photo on the document with a selfie using facial biometrics.
2. AML and sanctions screening
Once identity is verified, the individual is cross-referenced against international sanctions lists (OFAC, UN, EU), Politically Exposed Persons (PEP) lists, and adverse media sources. This step determines the initial risk profile.
3. Ongoing monitoring
KYC does not end at onboarding. Customers change: they appear on new sanctions lists, undergo changes in corporate control, or their transaction patterns deviate. Ongoing monitoring allows detecting these changes and updating the risk profile.
Best practices
- Risk-based approach: not all customers represent the same risk. Procedures should be proportional to the risk profile.
- Periodic updates: KYC data should be reviewed regularly — at least annually for high-risk customers.
- Consent and privacy: data collection must comply with local data protection regulations (GDPR in Europe, CCPA in California, LGPD in Brazil, etc.).
- Traceability and audit trail: every decision and every piece of data collected must be recorded to respond to an auditor or regulator.
- Avoid duplicate verifications: if the customer has already been verified by another entity in the same group, reusing that information (with proper consent) reduces friction without sacrificing control.
Frequently asked questions
Is KYC the same as AML?
Not exactly. AML (Anti-Money Laundering) is the broader regulatory framework for preventing money laundering. KYC is one of its key components: the process of identifying and verifying customers. Without KYC there is no effective AML, but AML also includes transaction monitoring, suspicious activity reporting (SAR), and compliance program governance.
How often should KYC be renewed?
It depends on the customer’s risk profile. A low-risk customer may be renewed every three to five years. A high-risk customer or PEP should be reviewed annually or upon any significant change. Regulators expect companies to document and justify their review frequencies.
Is it possible to do KYC without requesting documents from the customer?
In cases of very low risk and with specific regulatory thresholds, some jurisdictions allow simplified procedures that do not require complete documents. However, the regulatory trend is toward greater, not lesser, rigor. The ideal is to automate the process so it is smooth for the customer while remaining complete in data collection.
