A Beginner’s Guide to the US EIN Number: How to Apply for an Employer Identification Number with Confidence

Michel December 16, 2025

Expanding your business into the United States can feel both exciting and overwhelming, especially if you are just getting started. One of the very first steps in building a compliant and credible U.S. presence is obtaining a US EIN number. While the term may sound technical at first, the process becomes much simpler once you understand the basics.

An Employer Identification Number (EIN) is more than just a tax ID. In fact, it acts as the financial identity of your business in the United States. Whether you plan to register a company, open a U.S. bank account, hire employees, or file federal taxes, you must apply for an EIN before moving forward.

In this beginner’s guide, we will explain what an EIN is, why it matters, and how you can apply for EIN smoothly—especially if you are an international founder or an Indian entrepreneur entering the U.S. market.


What Is a US EIN Number?

To begin with, the US EIN number is a nine-digit number issued by the Internal Revenue Service (IRS). The IRS uses this number to identify businesses for tax and compliance purposes. In many ways, an EIN works like a Social Security Number, but instead of identifying individuals, it identifies businesses.

Moreover, the Employer Identification Number allows the U.S. government, banks, and financial institutions to track business activities accurately. As a result, it becomes a mandatory requirement for most registered entities in the U.S.


Who Needs an Employer Identification Number?

Now that you know what an EIN is, the next question is simple: do you need one?

You must apply for EIN if you:

  • Register a company in the USA

  • Open a U.S. business bank account

  • Hire employees in the United States

  • File federal or state business taxes

  • Operate as an LLC, C-Corporation, or Partnership

  • Run a U.S. subsidiary from India or another country

Therefore, if you are an Indian entrepreneur planning global expansion, obtaining an EIN is not optional—it is essential.


Why the EIN Is So Important for International Entrepreneurs

For founders outside the U.S., the EIN plays an even more critical role. Without it, you simply cannot move forward with core business activities. For example, banks will not allow you to open an account, payment processors will reject onboarding, and tax filings will remain incomplete.

Additionally, an Employer Identification Number helps establish trust. Vendors, clients, and investors often view EIN registration as proof that your business operates legitimately in the U.S. market. Consequently, this small step creates a strong foundation for long-term success.


How to Apply for EIN: A Step-by-Step Overview

When beginners hear “IRS application,” they often expect a long and confusing process. Fortunately, applying for an EIN is much simpler when done correctly.

Step 1: Confirm Your Eligibility

First, ensure your business qualifies for EIN issuance. You need a valid business structure and a responsible party who controls or manages the entity.

Step 2: Choose the Right Application Method

If you are a U.S. resident, you can apply online. However, international founders usually apply via Form SS-4, submitted by fax or mail.

Step 3: Provide Accurate Business Details

You must enter your legal business name, registered address, ownership details, and nature of operations. Accuracy matters because mistakes can delay approval.

Step 4: Submit and Wait for Confirmation

Once submitted correctly, the IRS issues your EIN. Depending on the method used, this may take anywhere from a few days to a few weeks.

Although the steps sound straightforward, international applications often require careful handling to avoid rejection or delays.


Common Mistakes to Avoid When Applying for EIN

At this stage, it helps to be cautious. Many beginners make avoidable mistakes, such as:

  • Entering inconsistent business names

  • Using incorrect address formats

  • Choosing the wrong entity classification

  • Submitting incomplete forms

Because of these issues, many founders turn to professional guidance rather than navigating the process alone.
