Know Your Customer

Key points

• KYC, short for Know Your Customer, is the procedure by which companies identify and verify who their customers are.
• It is a common requirement in the financial sector, tied to anti-money-laundering rules.
• It involves collecting data and documents, which brings responsibilities for protecting that information.

What is KYC?

KYC stands for Know Your Customer. It refers to the set of procedures by which a company, especially in the financial sector, identifies and verifies the identity of its customers before and during the relationship. The goal is to know who you are dealing with, a requirement widely adopted to prevent financial crimes and comply with legal obligations in various countries, including Brazil.

How it works

In practice, KYC usually involves collecting information and documents that prove the customer's identity, such as personal data and, depending on the case, additional proof and verifications. Institutions evaluate this data to confirm who the person is, and may apply different levels of verification depending on the risk and type of operation. This process typically happens when an account is opened and is revisited throughout the relationship.

KYC is closely linked to preventing money laundering and the financing of illicit activities. Knowing customers allows institutions to monitor operations, identify unusual situations, and comply with reporting obligations to the authorities as required. For this reason, KYC is not an end in itself, but part of a larger set of compliance duties that fall on financial service providers, including those operating with virtual assets.

In the crypto world, KYC has gained relevance as the sector has become regulated. Many services that bridge crypto and the traditional financial system need to identify their users, which contrasts with the pseudonymous nature of blockchains. This raises debates about privacy and access, but for regulated providers, complying with KYC is usually a requirement. Specific rules vary by country and evolve over time, and it is up to each institution to follow them according to applicable regulations.

Understanding KYC helps explain why regulated services ask for identification and what is behind this requirement.
