Learn what Know Your Customer means, how identity verification works, and why financial institutions and cryptocurrency platforms request personal data.

KYC is the process an institution or platform uses to understand who you are before enabling certain services. If you have ever submitted an identity document and taken a selfie when opening an account, you have probably completed a KYC check.

The information requested depends on the institution, product, account activity, and applicable rules. Requirements can change, and they should not be assumed to be identical across countries or accounts.

What does KYC mean?

KYC stands for Know Your Customer. It covers procedures used to verify a person’s identity, understand the account profile, and keep relevant information current.

KYC is one part of a broader framework for managing financial-crime and account risks. It does not, by itself, make a platform secure or eliminate fraud.

What is KYC used for?

  • Identity confirmation. It helps verify that a person is who they claim to be.
  • Impersonation controls. Comparing documents, personal data, and a liveness check can make identity theft harder.
  • Account profiling. An institution may request information about occupation, expected activity, or source of funds.
  • Record updates. Platforms may ask for refreshed information when an ID expires or relevant information changes.
  • Unusual activity reviews. Ongoing monitoring can lead to additional questions or checks.

How does KYC work step by step?

  1. 01

    Enter personal information

    You provide details such as your name, date of birth, address, and other information requested by the platform.

  2. 02

    Submit a valid identity document

    Depending on the case, the platform may request a driver’s license, passport, state ID, or another accepted document. It must be current and legible.

  3. 03

    Complete an identity check

    A selfie or short video may be compared with the photograph on the document and checked to confirm that a real person is present.

  4. 04

    Validate the information

    The platform reviews whether the information is consistent and may check it against sources or screening lists permitted by applicable rules.

  5. 05

    Refresh information when required

    KYC may continue after account opening. You may be asked to update an expired document or confirm information that has changed.

KYC, AML, and CDD

Term Meaning Purpose
KYC Know Your Customer Identify and verify the customer
AML Anti-Money Laundering Prevent and detect money laundering
CDD Customer Due Diligence Assess the relationship and its risks

The terms are related but not interchangeable. KYC focuses on identity; due diligence assesses the customer relationship; AML refers to a wider control framework.

What documents may be requested?

A platform may request a government-issued photo ID, proof of address, a selfie, or information about source of funds. The exact list depends on the institution and account. Do not submit documents through unexpected messages or links. Open the official app or website directly.

If Bitso asks you to refresh your verification, check the notice in the app and review the official guide on updating identity verification. This English-language information does not confirm product eligibility for every US resident.

Privacy and security during verification

Before sending personal information, verify the domain, review the privacy policy, and understand which data is requested and why. KYC involves sensitive data, so protect your password, enable two-factor authentication, and never share access codes.

Successful verification does not guarantee that an account can never be targeted by fraud. It is one layer of control that should be combined with good security practices.
