Employer Identification Number, EIN

Employer Identification Number, EIN — Meaning, Definition & Full Explanation

An Employer Identification Number (EIN) is a unique nine-digit tax identification number assigned to businesses, primarily in the United States, by the Internal Revenue Service (IRS) for reporting tax obligations. While the specific term "EIN" is not officially used in India, Indian businesses use equivalent identifiers like Permanent Account Number (PAN), Tax Deduction and Collection Account Number (TAN), and Goods and Services Tax Identification Number (GSTIN) for similar tax and regulatory compliance purposes.

What is Employer Identification Number (EIN)?

The Employer Identification Number (EIN), also known as a Federal Employer Identification Number (FEIN), serves as a unique identifier for businesses operating in the United States.
