The Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is a unique nine-digit identifier assigned by the Internal Revenue Service (IRS) for business entities operating in the United States. The primary purpose of an EIN is for identification of business tax accounts and various legal requirements.
An EIN is structured as follows: XX-XXXXXXX
Types of Entities Requiring an EIN

For corporations and Limited Liability Companies (LLCs), obtaining an EIN is mandatory to engage in business activities or establish a business presence domestically or internationally.
Partnerships
Partnerships, which are defined by the IRS as an association of two or more individuals engaged in a business, must also obtain an EIN.
Sole Proprietorships
While not always required, sole proprietors often need an EIN if hiring employees or establishing retirement plans.
Special Considerations
Non-Profit and Exempt Organizations
Non-profit organizations and trusts must acquire an EIN for tax filing and compliance purposes, especially when applying for tax-exempt status.
Estates and Trusts
For estates involved in probate or trusts requiring formal administration, obtaining an EIN is necessary for the proper management and allocation of assets.
Application Process

Businesses can apply for an EIN through the IRS’s online application system, enabling instant issuance of the number upon successful submission.

Applicants can also submit Form SS-4 by mail or fax. Processing times for these methods may vary, typically ranging from four weeks for mail submissions to four business days for fax submissions.
