What is KYC/AML in Bitcoin?

KYC and AML are not crypto-specific concepts. They come from traditional banking regulation, where financial institutions are required to verify customer identities and monitor transactions for suspicious activity. When crypto businesses grew large enough to be regulated, these same requirements followed.

What KYC means

Know Your Customer (KYC) is the process of verifying a customer’s identity before providing financial services. If you’ve ever signed up for a crypto exchange and been asked to upload a photo of your driver’s license and a selfie, that’s KYC. The exchange is satisfying its regulatory obligation to confirm you are who you say you are.

KYC requirements typically involve collecting a government-issued ID, proof of address, and sometimes a selfie or liveness check. For higher transaction volumes or business accounts, additional documentation may be required.

What AML means

Anti-Money Laundering (AML) refers to the policies and procedures financial institutions use to detect and prevent the use of their services for money laundering or financing illegal activity. This includes transaction monitoring, reporting suspicious activity to regulators, and maintaining records of transactions above certain thresholds.

Who KYC/AML applies to

What about merchants accepting Bitcoin directly?

This is the important distinction for small businesses. If you accept Bitcoin payments directly into your own wallet — peer-to-peer, with no intermediary processing the funds on your behalf — you are generally not acting as a Money Services Business and the KYC/AML obligations that apply to exchanges do not directly apply to you in the same way they apply to a financial institution.

You are receiving payment for goods and services, the same as accepting cash. The same general business obligations apply: keeping records, reporting income, complying with applicable tax law. You are not required to verify the identity of every customer who pays you in Bitcoin any more than you’re required to ID every cash customer.

When a merchant might encounter KYC

You will encounter KYC requirements when you open accounts with regulated crypto services: exchanges to convert received crypto to dollars, business Bitcoin wallets from regulated providers, or crypto banking services. These institutions are required to verify your identity before providing services, just as a bank does when opening a business account.
