When you apply for an Employer Identification Number (EIN), also known as a Federal Tax Identification Number, from the IRS, you might encounter a reference number. This EIN reference number serves as a crucial tracking mechanism for your application, especially if you're applying by mail or fax, or if you need to follow up on its status. It's not the EIN itself, but rather a temporary identifier linked to your specific submission. Understanding its purpose and how to use it can streamline the process of obtaining your business’s tax ID, a foundational step for any new LLC, Corporation, or Sole Proprietorship operating in the United States. This guide will break down what an EIN reference number is, why it's important, and how it relates to your overall business formation journey with services like Lovie. For businesses formed in states like Delaware, California, or Texas, securing an EIN is a mandatory step before opening business bank accounts, hiring employees, or filing certain tax returns.

The reference number is your key to this tracking. It’s a unique code generated by the IRS to acknowledge receipt of your application and to facilitate any necessary communication or updates regarding your EIN status. Without it, resolving issues or confirming your application's progress can be significantly more challenging, potentially delaying critical business operations. Lovie helps thousands of entrepreneurs navigate these essential steps, ensuring their business formation is smooth and compliant from day one.
An EIN reference number is a unique identifier assigned by the Internal Revenue Service (IRS) to a specific EIN application. It is not your EIN itself, but rather a confirmation or tracking number associated with your submitted application. Think of it as a receipt number for your tax ID application. This number is particularly relevant when you apply for an EIN through methods other than the instant online application, such as by mail (Form SS-4) or fax. When the IRS receives your application, they may issue this reference number to acknowledge that your submission is in their system and is being processed. This number typically appears on the confirmation letter or notice the IRS sends back to you, or it might be provided during the fax confirmation process. The primary purpose of the EIN reference number is to facilitate communication and tracking. This connects to our resource on the Alaska LLC filing process, which covers the details. If you need to contact the IRS about your application's status, inquire about delays, or correct any information, this reference number will be essential. It allows IRS agents to quickly locate your specific application among the thousands they process daily. Without it, proving you submitted an application or getting specific updates can be difficult. For instance, if you're forming a Limited Liability Company (LLC) in Florida and submitted your EIN application via fax, the fax confirmation page might include this reference number. It’s a vital piece of documentation that confirms your application is officially with the IRS, helping to avoid duplicate applications or misunderstandings about your business's tax identification status. It’s a critical component in the early stages of establishing your business entity’s identity with the federal government.
The importance of an EIN reference number lies in its role as a communication and verification tool. When you're establishing a new business entity, such as a C-Corporation in New York or an S-Corporation in Texas, obtaining an EIN is a critical step. This number is required for various business activities, including opening bank accounts, hiring employees, and filing business taxes. If there are any issues with your EIN application, or if you need to confirm that the IRS has received and is processing it, the reference number is your primary point of contact. It acts as proof of submission and allows the IRS to efficiently retrieve your application details. Consider a scenario where you've formed a nonprofit organization in California and applied for your EIN by mail. Weeks go by, and you haven't received your EIN. For related guidance, see our article on forming an LLC in Arizona. Without a reference number, contacting the IRS can be a lengthy and frustrating process, often involving long hold times and general inquiries. However, with the reference number, an IRS representative can immediately access your application, identify any bottlenecks, and provide you with specific information about its status. This is crucial for maintaining your business formation timeline and avoiding operational delays. For example, if your LLC in Nevada needs to issue stock or enter into contracts, having the EIN confirmed promptly is essential. The reference number ensures that you have a clear path to follow up, making the entire process of obtaining your Federal Tax ID smoother and more predictable. It’s a small but significant detail that can save considerable time and potential headaches.
Obtaining an EIN reference number is typically tied to the method you use to apply for your EIN. The most straightforward way to get an EIN is through the IRS's online application portal. This method usually provides immediate confirmation of your EIN upon successful submission, and you generally do not receive a separate 'reference number' in the traditional sense. Instead, you get your EIN directly. However, if you choose to apply by mail using Form SS-4 or by fax, the reference number becomes relevant. When you fax your completed Form SS-4 to the IRS, the confirmation page you receive back from the fax machine often includes a reference number. This is your proof of submission and a tracking mechanism. If you mail your application, you might receive a confirmation letter from the IRS that includes a reference number, though this is less common than with fax submissions. The IRS uses this number internally to track your application's progress through their manual processing systems.
Using your EIN reference number is straightforward: keep it in a safe place along with your completed Form SS-4 and any other relevant documentation. If you need to contact the IRS for any reason related to your EIN application – perhaps you haven't received your EIN within the expected timeframe (which can be several weeks for mail/fax applications, compared to minutes for online applications) or you need to clarify information – you will need to provide this reference number. You can reach the IRS Business & Specialty Tax Line at 800-829-4933. Be prepared to provide other identifying information about your business as well. For example, if you're forming a sole proprietorship in Illinois and applying by mail, and you need to follow up, quoting your reference number will significantly speed up the IRS agent's ability to assist you. It’s a key piece of information that bridges the gap between your submission and the IRS's processing system, ensuring efficient handling of your business’s tax identification needs.
It is crucial to distinguish between an EIN (Employer Identification Number) and an EIN reference number. The EIN is the permanent, nine-digit Federal Tax Identification Number assigned to your business entity by the IRS. It’s akin to a Social Security Number for your business. You need this number to operate legally, open bank accounts, file taxes, and conduct various other business transactions. It is a permanent identifier that stays with your business throughout its existence, unless specific circumstances necessitate a change (which is rare).
In contrast, the EIN reference number is a temporary, transient identifier. It is only associated with the application process itself. Once your EIN is issued, the reference number typically becomes obsolete. Its sole purpose is to help you and the IRS track the application while it's pending. For example, if you formed an LLC in Wyoming and applied via fax, you might receive a reference number like 'FAX-APPL-12345'. This number helps you confirm receipt. The actual EIN you receive might be something like 'XX-XXXXXXX'. The reference number has no bearing on your business operations after you have your official EIN. It’s a procedural tool, not a functional identifier for your business. Understanding this distinction ensures you don't mistake a temporary tracking code for your business's official federal tax ID, which could lead to confusion and administrative errors when dealing with banks, vendors, or the IRS itself.
Losing your EIN reference number can feel like a setback, especially if you need to follow up on your application. However, it's not the end of the world, and there are steps you can take. If you applied online and received your EIN immediately, you likely never had a formal reference number to begin with, and you should simply use your issued EIN. If you applied by mail or fax and misplaced the reference number, the first step is to check all your records thoroughly. Look through emails, physical mail, and any notes you made during the application process. If you faxed your application, check the confirmation page that was printed out by your fax machine – sometimes these get filed away and forgotten. If you submitted via mail, review any correspondence received from the IRS. Sometimes, the IRS may send a confirmation letter that includes this number, even if it wasn't on the initial fax confirmation.
If, after a diligent search, you still cannot locate the reference number, your next course of action is to contact the IRS directly. You can call the IRS Business & Specialty Tax Line at 800-829-4933. Explain that you applied for an EIN, believe you were issued a reference number, but can no longer find it. Be prepared to provide as much information as possible about your business and the application. This includes your business name, the name and SSN of the responsible party (usually the applicant), the business address, and the approximate date you submitted the application. The IRS representative can often locate your application using this information, even without the reference number. They may then be able to provide you with the necessary details or guide you on how to proceed. While having the reference number makes the process smoother, the IRS is equipped to handle inquiries even when this specific piece of documentation is missing, ensuring your business formation in states like Pennsylvania or Colorado can still move forward.
