Short answer

KYC means Know Your Customer. US crypto exchanges must verify your identity under federal anti-money-laundering law before you open an account or move dollars on a regulated custodial platform. Self-custody wallets usually fall outside it.

KYC comes from the Bank Secrecy Act. FinCEN requires money services businesses to run a written Customer Identification Program, and crypto exchanges that hold your dollars fall into that group. The platform also keeps watching your activity while you are a customer.

What Does KYC Mean in Crypto?

KYC stands for Know Your Customer. It is a set of laws and rules that require regulated businesses to verify a customer's identity. In crypto, a regulated exchange has to know who you are before it lets you trade or move money.

When Do Crypto Platforms Require KYC?

KYC applies when you open an account, trade, or move fiat money on a regulated custodial platform. Self-custody wallets, peer-to-peer transfers and non-custodial swaps usually fall outside the rule.

What Information Do Crypto Exchanges Collect?

  • Legal name
  • Date of birth
  • Home address
  • Social Security number
  • Photo of your government ID

Who Enforces Crypto KYC in the US?

FinCEN enforces the Bank Secrecy Act and its customer identification program for money services businesses. The FinCEN 2004 CIP Rule requires a written, risk-based Customer Identification Program. The 2016 CDD Rule added ongoing monitoring.

What If You Refuse Crypto KYC?

If you refuse KYC, a regulated exchange may deny, freeze, or close your account. The platform can lose its license if it serves customers it has not identified.
