How to Find Your EIN: A Complete Guide | Lovie

The Employer Identification Number (EIN), also known as the Federal Tax Identification Number (FTIN), is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States. Think of it as a Social Security number for your business. It's essential for a wide range of business activities, including opening a business bank account, filing business tax returns, hiring employees, and applying for business licenses and permits. Without an EIN, operating a formal business can be extremely difficult, if not impossible, especially if you plan to form an LLC, Corporation, or hire staff. Many business owners, particularly those just starting out or those who formed their business some time ago, may find themselves needing to locate their EIN. For more details, see our guide on starting a business in Alabama. This can happen for various reasons: misplacing the original documentation, the responsible party leaving the business, or simply not keeping track of important business documents. Fortunately, the IRS provides several methods to help you retrieve a lost or forgotten EIN. This guide will walk you through the most common and effective ways to find your EIN, ensuring you have the necessary information to keep your business compliant and operational.

Check Your Existing Business Records

The most straightforward way to find your EIN is to check the official documents you received when your business was first established or when you applied for the EIN. This is often the quickest and easiest method if you've maintained good record-keeping practices. When the IRS assigns an EIN, they typically send out a Confirmation Letter, also known as CP 575, to the business owner. This letter explicitly states your business's legal name and the EIN assigned to it. It's a crucial document, and you should keep it in a safe place with other important business formation paperwork. If you can locate this letter, your EIN will be clearly visible. You can learn more about LLC registration in Alaska to understand the full picture. Beyond the CP 575 letter, your EIN may also be found on other official business correspondence from the IRS. This could include tax returns you've filed for your business (e.g., Form 1120 for corporations, Form 1065 for partnerships, or Schedule C filed with your personal Form 1040 if you operate as a sole proprietor with an EIN), notices from the IRS about your business's tax obligations, or any other official communication. Reviewing these documents can often reveal the nine-digit number you're looking for. If you formed your business with a service like Lovie, check any welcome packets or digital copies of your formation documents you received, as some services may include your EIN if it was obtained as part of the formation process.

Contacting the IRS Directly for Your EIN

If you've exhausted your internal records and still cannot locate your EIN, the next step is to contact the IRS directly. The IRS has specific procedures in place to help taxpayers retrieve their EINs. It's important to note that the IRS will only provide the EIN to the authorized individual associated with the business. This is a security measure to prevent identity theft and ensure that sensitive business information is not disclosed to unauthorized parties. To contact the IRS, you can call their Business & Specialty Tax Line at 800-829-4933. The hours of operation are typically Monday through Friday, from 7:00 AM to 7:00 PM local time. When you call, be prepared to provide specific information to verify your identity and your business's legitimacy. This usually includes:

The business's legal name The business's address (as listed with the IRS) The name and Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) of the principal officer, grantor, general partner, owner, or member of the entity. We cover this in depth in our resource on setting up your Arizona LLC. The type of business entity (e.g., LLC, Corporation, Partnership). Be aware that the IRS representative will ask you questions to confirm you are the authorized person to receive this information. They will not give out your EIN over the phone to just anyone. If you are not the sole proprietor or the principal officer listed on the original application, you may need to provide additional documentation or have that authorized person make the call. This process can sometimes take time, so patience is key. For businesses located outside the United States, you can contact the IRS at 267-941-1000 (not toll-free). Similar verification procedures will apply.

Requesting Your EIN via Mail or Fax

If you prefer not to call the IRS or need a more formal written record, you can request your EIN information by mail or fax using Form 4506-T, Request for Transcript of Tax Return. While this form is primarily for requesting tax transcripts, it can also be used to obtain information about your EIN if you no longer have your original documentation. You will need to complete the form accurately, specifying the tax year for which you need the information and indicating that you are requesting information related to your EIN.

When filling out Form 4506-T, ensure you select the appropriate "line" or "schedule" that corresponds to your business tax filings where the EIN would have been used. For example, if you're a corporation, you'd be looking for information related to corporate tax returns. You'll need to provide your business's name, address, and the EIN you are trying to locate. The IRS will then process your request and mail a transcript or relevant documentation to the address on file for your business. This method can take longer than a phone call, often several weeks, but it provides a documented request and response.

Alternatively, you can submit a written request for your EIN on company letterhead. This request should include your business's full legal name, address, the name and title of the authorized individual making the request, and their SSN or ITIN. You can mail this request to the IRS address specified for Form 4506-T. For faster service, you can often fax the request to the appropriate IRS fax number, which can be found on the IRS website or within the instructions for Form 4506-T. Remember to include a return fax number if you choose this option. As with phone requests, the IRS will need to verify your identity and authorization.

Check Business Bank Accounts and Credit Reports

Your EIN is a critical piece of information used when establishing financial relationships for your business. If you have a business bank account, credit cards, or loans in your business's name, your EIN would have been required to open these accounts. Therefore, checking your business bank statements, loan documents, or credit card statements can often reveal your EIN.

When you open a business bank account, the bank is required to verify your business's identity, which includes obtaining your EIN. This number is typically listed on monthly statements, checks, and any official correspondence from the bank regarding your business account. Similarly, business credit reports, which track your company's borrowing history and payment performance, will prominently feature your EIN. If your business has ever applied for or received a business loan or credit line, the lender would have reported your EIN to the credit bureaus.

Reviewing these financial documents can be a surprisingly effective way to recover your EIN, especially if you've been actively managing your business finances. It’s a good practice to keep copies of all financial agreements and statements organized, as they serve as a comprehensive record of your business's financial activity and its associated identification numbers. If you can't find it on a statement, contact your bank or credit provider directly; they should be able to provide it to you after verifying your identity as an authorized signer on the account.

Special Considerations for EINs

Understanding specific scenarios can help when searching for your EIN. For instance, if you operate as a sole proprietor and decided to obtain an EIN for your business (which is optional but recommended for separating personal and business finances), your EIN is tied to your business name, not your Social Security Number. This is a common point of confusion. If you never formally registered a business entity like an LLC or Corporation with your state, and only obtained an EIN as a sole proprietor, the IRS records will link the EIN to the business name you provided during the application.

If your business structure has changed (e.g., from a sole proprietorship to an LLC, or an LLC to a C-Corp), you may have been issued a new EIN. It's crucial to use the correct EIN associated with your current business entity structure. When forming a new business entity like an LLC or Corporation with Lovie, we can assist you in obtaining a new EIN if one is required based on your entity type and state of formation. Remember, you cannot simply 'transfer' an EIN from one business entity to another; a new EIN is typically issued for a new legal entity.

For non-profit organizations, the process of obtaining and managing an EIN is similar, but the tax filings and requirements differ. Ensure you are using the correct EIN for any tax-exempt filings or grant applications. If you've dissolved a business and are unsure about its EIN status, the IRS generally retains records for a significant period. However, once a business is officially closed and all tax obligations are met, the EIN is retired but not typically reassigned. If you need to re-establish a business under a similar name in the future, a new EIN will be necessary.
