Understanding what is an EIN Number: What and Why You Need One

Starting a fintech startup comes with its own set of financial and legal requirements, one of which is obtaining an Employer Identification Number (EIN). In this blog post, we will discuss the importance of EIN numbers, what they stand for, and their various uses. We will also clarify the differences between EIN and other identification numbers such as Tax ID and TIN.

What is an EIN Number?

An EIN, or Employer Identification Number, is a unique nine-digit federal tax number assigned by the Internal Revenue Service (IRS) to businesses operating in the United States. It is used for tax filing and reporting purposes, as well as for identifying a business entity.

What Does EIN Stand For?

EIN stands for Employer Identification Number. It is sometimes referred to as a Federal Employer Identification Number (FEIN) or Federal Tax Identification Number (FTIN).

What is an EIN Number Used For?

An EIN number is primarily used for tax filing and reporting purposes. It allows the IRS to identify and track business entities and their financial activities. In addition, an EIN may be required when filing various business tax returns, applying for business licenses, opening a business bank account, and hiring employees.

Is EIN the Same as Tax ID?

While EIN is a type of Tax ID, not all Tax IDs are EINs. A Tax ID is a generic term for a unique identifier assigned by a tax authority, such as the IRS. An EIN is specifically assigned to businesses, while other types of Tax IDs include Social Security Numbers (SSNs) for individuals, Individual Taxpayer Identification Numbers (ITINs) for non-resident aliens, and Preparer Taxpayer Identification Numbers (PTINs) for tax professionals.


An EIN (Employer Identification Number) is assigned to businesses, whereas a TIN (Taxpayer Identification Number) is a broader term that encompasses EINs, SSNs (Social Security Numbers), ITINs (Individual Taxpayer Identification Numbers), and PTINs (Preparer Taxpayer Identification Numbers). Both EINs and TINs are used for tax filing and reporting purposes, but they are assigned to different types of taxpayers.

Separate EIN for Different Business Structures

Depending on the corporation tax structure, a business may need a separate EIN if it undergoes significant changes, such as converting from a sole proprietorship to a corporation or merging with another entity.


Understanding the nuances of EIN numbers is crucial for fintech startups looking to operate within the US. By obtaining and properly using an EIN, your business can maintain compliance with the IRS and streamline its financial and legal processes. While dealing with EINs is a necessary step, partnering with a comprehensive embedded finance platform like Cybrid can significantly simplify other aspects of starting and managing your fintech startup.
