How do I get an EIN Number?

January 24, 2025

By SurePayroll Editorial Team

New small business owner learns how to get an EIN number online.
Getting an EIN from the Internal Revenue Service (IRS) is easy and free.

What is an EIN?

An Employer Identification Number (EIN), sometimes referred to as a Federal Identification Number (FEIN), is used by the IRS to identify a business entity, including:  

  • Business name  
  • Business official filing address  


This nine-digit number helps a business operate legally in the United States.  

Any U.S. business with employees needs an EIN. A business also needs an EIN to open a business bank account, hire workers, and obtain loans.  

You will also use it to file taxes and obtain business licenses and permits.  

How to Apply for an EIN

Getting an EIN through the IRS is easy and free.  

Online

You can use the Internet EIN application tool to get an EIN directly from the IRS in minutes.  

You can use this tool if your principal place of business is in the U.S. or U.S. territories, you’re the responsible party or its authorized representative, or you have the responsible party’s Social Security or individual taxpayer ID number.  

You’ll also need to know your business entity type. If you’re the third-party designee, you must have signed authorization to apply.  

Be prepared to complete the application in one session. The IRS notes you cannot save it for later. If your application is approved, the IRS will issue your EIN immediately online. You’ll be able to print your EIN confirmation letter for your records.  

Other Ways to Apply  

You can also apply for an EIN by:  

  • Faxing your completed Form SS-4 to the appropriate fax number. If you provide your return fax number, you could receive your EIN via fax within four business days.  
  • Mailing your completed Form SS-4 to the address noted on the form. Processing for mailed applications is usually four weeks.  


International applicants can call 267-941-1099 to obtain their EIN.  

If you don’t receive your IRS EN letter more than 10 weeks after filing your SS-4, contact the IRS at 800-829-4933.


‍Why You Need an EIN

This documentation plays a pivotal role in various aspects of business operations, including:  

  • Tax Filing. The EIN is required for filing federal tax returns and other tax-related documents. It helps ensure your business is compliant with IRS regulations and helps you avoid penalties.  
  • Banking and Financial Transactions. Most banks require an EIN to open a business account.  
  • Employment. When hiring employees and running payroll, your EIN is used to report payroll taxes to the IRS.

How to Manage Your EIN

Once you have your EIN Verification Letter, ensure you store it securely. Consider keeping both digital and physical copies.  

Effective management of your EIN and related documents is crucial for smooth business operations. Here are some best practices.  

  • Organize Your Documents. Keep all important documents, including the CP-575 form and EIN Verification Letter, in a well-organized and secure location. A dedicated folder, both physical and digital, can help prevent loss or misplacement.  
  • Regularly Update Your Information. If your business details change, such as your address or business name, update the IRS promptly to ensure all records remain accurate. Use Form 8822-B to report changes to Form SS-4. This minimizes the risk of miscommunication and ensures you receive all correspondence.  
  • Use Your EIN Correctly. Always use your EIN for business-related activities. Avoid using your EIN for personal transactions.
