Know Your Customer (KYC) are a set of standards used within the investment and financial services industry to verify customers, their risk profiles, and financial profile.

In the US, the Financial Crimes Enforcement Network (FinCEN) established minimum KYC requirements, including verifying beneficial owners and setting standards for dealing with third parties.

This information is used to combat money laundering and terrorist financing and is required under various legislation including the US Patriot act.
