What is KYC?

KYC stands for Know Your Customer. It refers to the identity verification procedures that banks, exchanges, payment processors, and other regulated financial institutions are required to perform on their customers. KYC is part of a broader set of regulations aimed at preventing money laundering, terrorist financing, and other financial crimes.

In practice, KYC means providing your name, address, date of birth, government-issued ID, and sometimes a selfie or proof of address. The institution verifies these details against government databases, sanctions lists, and (in some cases) politically exposed persons (PEP) lists.

KYC and crypto

KYC is required by virtually every centralized crypto exchange (Coinbase, Kraken, Binance, etc.), every major crypto payment processor (BitPay, Coinbase Commerce, NOWPayments for higher volumes), and every custodial wallet provider. It is the single largest reason the pseudo-anonymous reputation of crypto doesn’t match reality at the on-ramp and off-ramp.

Crypto-native alternatives exist — non-custodial wallets, decentralized exchanges, and peer-to-peer platforms — but they trade off convenience, liquidity, and legal protection. Most people going through a regulated payment processor will go through KYC at some point in the flow.

AML

KYC is closely tied to AML (Anti-Money Laundering) regulations. The combination of KYC and AML is what regulators use to ensure that crypto is not being used to launder the proceeds of crime. For users, this means the exchange or processor is required to:

• Verify your identity before letting you transact above certain thresholds.
• Report suspicious activity to financial intelligence units.
• Comply with sanctions (OFAC in the US, EU sanctions, etc.) and freeze accounts linked to sanctioned individuals or jurisdictions.

Levels of KYC

Most platforms tier their KYC requirements by transaction size:

• No or minimal KYC — small purchases, often only for buying crypto with cash (e.g., Bitcoin ATMs).
• Basic KYC — name, address, date of birth, ID number. Typically allows transactions up to a few thousand dollars per day.
• Enhanced KYC — full identity verification, proof of address, source of funds documentation. Required for higher limits and institutional accounts.

Privacy trade-offs

If you value financial privacy, the on-ramp is where you give up the most. Once crypto is in a non-custodial wallet, no one is running KYC on your transactions. But the moment you cash out through a regulated exchange, your activity is again linked to your identity. This is why privacy-conscious users often prefer to keep spending balances in non-custodial wallets and use regulated on-ramps and off-ramps sparingly.
