Crucial Step: Employment Identification Number
2/5/20251 min read


Getting an Employer Identification Number (EIN) is a must for businesses, and knowing how to do it is key. This guide covers the different ways to get an EIN and when it might make sense to use a professional service like Open-LLC.
Understanding the EIN Application Process
The IRS provides EINs for free. Open-LLC offers this service for a fee, saving you time so you can focus on your business.
Application Methods
Online: The IRS website is the quickest way to get an EIN. You'll get it instantly after your information is verified. However, you need a U.S. Social Security Number (SSN) for this method.
Fax: You can fax Form SS-4 to the IRS. The IRS will process your request and issue your EIN, usually within four business days. Processing times may be longer during busy periods.
Mail: Mailing Form SS-4 to the IRS takes about four weeks. Make sure the form is complete and accurate.
Telephone (International Applicants Only): International applicants can call 267-941-1099 (not toll-free) Monday through Friday, 6:00 a.m. to 11:00 p.m. Eastern Time. You must be authorized to receive the EIN and be able to answer questions about Form SS-4.
Key Points to Remember
Responsible Party: This is the person or entity that controls the business. For non-government entities, the responsible party must be an individual.
Third-Party Authorization: If you use a service like Open-LLC, make sure Form SS-4 is signed, authorizing them to receive the EIN on your behalf.
EIN Issuance Limit: The IRS limits EIN issuance to one per responsible party per day. This applies to all application methods.
Process Updates: The IRS has made changes to the EIN process to ensure accuracy. Check the IRS website for the latest information.
Using Open-LLC for EIN
While you can apply for an EIN yourself, consider if it's the best use of your time. Mistakes can cause delays. Open-LLC can handle the process efficiently, ensuring accurate and timely EIN issuance.
