The Federal Employer Identification Number (FEIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to businesses and other entities for tax purposes. Understanding the FEIN is crucial for any business owner or organization, as it plays a significant role in the financial and legal operations of an entity. Here are five key facts about the FEIN that highlight its importance and application in the business world.
What is a FEIN and Its Purpose?

A FEIN, also known as an Employer Identification Number (EIN), is used to identify a business entity and is required for various purposes, including filing tax returns, opening bank accounts, and hiring employees. The IRS issues FEINs to businesses, non-profits, and other entities to track their tax obligations and ensure compliance with federal tax laws. Each FEIN is unique to the entity it is assigned to, ensuring that the IRS can accurately identify and monitor the financial activities of different businesses and organizations.
Obtaining a FEIN
To obtain a FEIN, an entity must apply through the IRS, either online, by phone, or by mail. The application process involves providing specific information about the business, such as its name, address, and type of business structure (e.g., sole proprietorship, partnership, corporation). Applicants must also identify the responsible party, who is the individual or entity that controls, manages, or directs the business and is responsible for its tax obligations. The IRS typically issues a FEIN immediately after receiving a complete application, allowing businesses to quickly proceed with their financial and operational setup.

Additionally, businesses use their FEIN to open business bank accounts, apply for credit, and establish lines of credit, highlighting the FEIN’s role in facilitating financial transactions and access to capital.
Security and Confidentiality
