What is an alternative number that can be given to clients instead of a Social Security Number?

The Employer Identification Number (EIN) is an appropriate alternative to a Social Security Number (SSN) that can be provided to clients, particularly in contexts involving businesses or organizations. The EIN is issued by the Internal Revenue Service (IRS) and specifically functions as a unique identifier for a business entity. This number is often utilized for tax reporting purposes, opening business bank accounts, and applying for certain licenses.

For clients needing to share a number that does not expose their personal Social Security Number, an EIN serves as a secure alternative, especially when the interactions are business-related. It does not provide personal information about the individual, maintaining a layer of privacy that a Social Security Number would not offer.

In contrast, other options like a Driver's License Number or a Personal Identification Number (PIN) may not serve the same purpose or provide the necessary protections and privacy in a business context. A Tax Identification Number (TIN) is indeed another alternative, but it can often refer to a SSN in individual contexts. Thus, while other options might present valid identification alternatives in different scenarios, the EIN is specifically tailored for business-related circumstances and is the correct choice in this context.
