This guide is intended to assist communications service providers (CSPs) in beginning the development of processes and procedures to know their customers and conduct meaningful customer due diligence. The information enclosed may be useful to anyone working in communications but is most specifically intended for those establishing or performing Know Your Customer (KYC) functions.

This guide focuses on CSPs that provide services to businesses and other CSPs rather than CSPs that work with consumers. Each CSP should adapt its process and procedures to best fit the nature of its business and its risk mitigation policies. This guide is not intended as legal advice or opinion.
