What is the FEI number in the US?
I'm curious to know, what exactly is the FEI number in the United States? Is it a unique identifier for businesses or individuals in the financial or cryptocurrency sector? Could you please elaborate on its significance and purpose in the context of financial transactions and regulatory compliance? Also, how does one acquire or obtain an FEI number, and what are the steps involved in the process? I'm particularly interested in understanding its role in the cryptocurrency industry and how it impacts the overall financial landscape in the US.
