How Do I Look Up A Company’s EIN?

The Employer Identification Number (EIN) is a nine-digit identifier specific to your business issued by the International Revenue Service (IRS). You can think of an EIN as something similar to a Social Security Number, as it is used to differentiate you from other businesses for tax purposes. 

But how do you look up a company’s EIN if the need comes up? Let’s find out. 

What is an EIN of a company?

An EIN, also known as an Employer Identification Number, is a nine-digit number issued by the Internal Revenue Service (IRS) and used for US tax purposes. Sometimes, you may see it referred to as a Federal Tax Identification Number (TIN). 

An EIN helps the IRS track businesses for the purposes of tax reporting and payments. If you have a business, whether a corporation or a non-profit organization, you most likely need an EIN. They are also sometimes used by banks to help verify a business’s identity when opening a bank account and by the government when you apply for special permits or licenses for your company.

Why is it important to know your company’s EIN?

There are many reasons why you need to know and may need to look up your company’s EIN. The main reason is for tax purposes and to help you file your business taxes, pay employment taxes, and report any tax-related information. Banks and financial institutions will also require an EIN to open a bank account. Without one, it can make it challenging to manage your finances. 

If you ever want to apply for a business license or permit with the government, you will need your EIN, which will help ensure you operate your company legally. 

Knowing your company’s EIN is essential to ensure you’re being compliant with federal tax laws and other legal requirements and make sure your business is up to scratch.

Where To Find Your Own Company’s EIN

If you forgot or misplaced your company’s EIN and needed to find it for business purposes or any other reason, there are a few ways that you can quickly look it up. 

Look Up Your Old Business Tax Returns

The best place to start is to look through your company’s old IRS forms. Your business tax returns will contain the EIN.

Look Up Your Old Business Records

You can also look at your company’s other documents that contain the EIN information. These business records can include your business bank account number, business license, or credit report. 

Contact Your Accounting Department

If your company has an accounting department, call them to get your company’s EIN. The accounting department keeps detailed records of the company’s finance, and for sure, they will have the IEN information you are looking for. 

Call the IRS

If you are your company’s authorized representative, you can call the IRS to retrieve your company’s EIN. You can contact the Business & Specialty Tax phone number between 7 am and 7 pm at 800-829-4933. You will be asked to prove that you are your company’s authorized representative, and once you’ve provided that information, they will give you the EIN. 

How To Find Another Company’s EIN

Depending on what industry your business is in, there might come a time when you need to get another business’ EIN. Whatever reason you want to know another company’s EIN, there are several ways to look it up.

Use An EIN Lookup Service

If you are doing an EIN lookup for a public company; you look it up using the Electronic Data Gathering, Analysis, and Retrieval (EDGAR). It’s a Securities and Exchange Commission (SEC) database where you can type in a business name, and all its publicly filed information will come up. 

For private companies, however, finding an EIN isn’t as easy, as they are not included in EDGAR. Using a paid EIN lookup service is your best bet, as you can search millions of EINs through a database without any hassle. 

Contact The Company Directly

The more time-consuming way to get another company’s business EIN is to contact them. Call or send an email explaining why you need to get their company’s EIN. This method does not guarantee success, and you may end up waiting days for an answer.
