Whether you’re planning to start a business in the U.S. or already operate from abroad, one of the first questions you’ll face is: What is my tax identification number?
This number—officially known as the Taxpayer Identification Number (TIN)—is essential for doing business legally, paying taxes, opening bank accounts, and hiring employees.
But here’s where the confusion starts: many assume that TIN and SSN (Social Security Number) are the same. They’re not. The TIN is a broader category that includes different numbers depending on your profile: SSN, ITIN, EIN, PTIN, or ATIN.
In this guide, we’ll walk you through:

This number serves multiple purposes:
If you are not a resident or U.S. citizen, you will likely need a different type of TIN, such as an ITIN or EIN.

To help you better understand which type of Tax Identification Number (TIN) you need, here’s a clear and updated comparison table:
If you’re a U.S. citizen and just formed an LLC, you might assume your SSN is enough. But to properly manage your business, open bank accounts, and file business taxes, you need a specific number for your company: the EIN.

If you’re not a U.S. citizen or resident but want to start a business or invest in the U.S., you don’t need an SSN—but you do need a TIN that fits your profile.

1. What is a Tax Identification Number in the United States?
The Tax Identification Number (TIN) is a unique number used by the U.S. government to track tax obligations. It can be an SSN, EIN, ITIN, among others.
2. What TIN do I need if I own a business in the U.S. but I’m not a citizen?
If you don’t have an SSN but want to operate legally, you’ll need another type of TIN based on your profile—most commonly an EIN or ITIN.
3. Can I use my SSN for business activities?
It’s not recommended. The SSN is for personal use. To operate a business, you need a separate tax number like an EIN.
4. Does an ITIN allow me to work in the U.S.?
No. The ITIN does not grant work authorization—it’s only for fulfilling tax obligations.
5. Can I open a bank account without an SSN?
Yes, but you’ll need a valid TIN and other supporting documents. At Prodezk, we help you meet all the requirements.
