KYC

Short for 'know your customer'. Oftenly used in trading websites to avoid scams by making users send a Photo of their ID, of their Phone bill or something similar.

The IRS would define KYC, or Know-Your-Customer, as the applicable laws, regulations, rules, and administrative practices and procedures governing the requirements of financial institutions (e.g., Coinbase) to obtain documentation confirming the identity of account holders. However, in the Bitcoin space, KYC is often used more generally and refers to ANY time an entity asks a user for information which does not necessarily confirm the users identity but requires the information before the user can sign-up and utilize the entities services, such as name, phone number, email, and payment methods, such as a debit card.
