What is Coinbase Ein number?

Could you please clarify what the Coinbase EIN (Employer Identification Number) stands for and why it is important? As a cryptocurrency user and investor, I've often come across references to Coinbase and its various services, but the mention of an EIN number piques my interest. Is this a unique identifier that Coinbase uses for tax purposes? Or does it serve a different function? Understanding this aspect of Coinbase's operations could help me navigate any potential tax-related matters more effectively. Your insights would be greatly appreciated.
