EIN verification, or Employer Identification Number verification, is a security process, often used as an extra component in the Know Your Customer (KYC) or Know Your Business (KYB) verification process for identification and regulatory compliance purposes. The unique nine-digit number that’s issued by the IRS for tax reporting purposes, is the equivalent to the Taxpayer Identification Number (TIN), but in the context of verification and identification, it’s used for corporate clients, aka other companies, often during a KYB check during onboarding as a way to verify if the entity is operating legally and is legitimate.
Various entities are eligible to receive an EIN, including entities like limited liability companies (LLCs), sole proprietorships, partnerships, and corporations, among others. The main reason why businesses need EINs is that they are required to legally operate in the US. By verifying and validating if an entity’s EIN number is legitimate, businesses can identify risks and improve their KYB processes.
