How it works
The user submits a government ID, a selfie, and proof of address (utility bill or bank statement). The platform verifies the documents against issuing-authority databases and biometric checks. Higher account tiers require additional documentation: source of funds, employment, expected trading volume. The data is held by the platform and shared with regulators on lawful request.
Example
A user opens a Coinbase account. Basic KYC takes 10 minutes (passport photo, selfie, address verification) and unlocks deposits and trading. Higher tiers require additional information for tax reporting and withdrawal-limit increases. The data is encrypted at rest and protected under data-protection laws like GDPR in the EU and CCPA in California. The platform reports suspicious activity and certain transaction volumes to financial-intelligence units.
Why it matters
KYC is the regulatory price of access to fiat ramps and major liquidity. It satisfies anti-money-laundering rules and lets regulated platforms operate. The trade-off is privacy: identity, residency, and trading patterns are tied to government-issued ID. Users who prioritise privacy may use peer-to-peer markets, non-custodial DEXes, or layer-2 protocols with lower KYC friction. Most active traders accept KYC for the liquidity and stability of regulated venues.
