Where to Find My EIN Number: A Comprehensive Guide

An Employer Identification Number (EIN) is like a Social Security number for your business. Issued by the Internal Revenue Service (IRS), this unique nine-digit number is crucial for businesses operating in the United States. Whether you’re a new business owner or have been running your company for years, there might come a time when you need to locate your EIN. Perhaps you’re opening a new bank account, applying for a loan, or filing your business taxes and suddenly realize you can’t readily put your hands on your EIN. If you’re wondering “Where To Find My Ein Number,” you’re not alone. This guide will walk you through the most reliable ways to locate your missing EIN, ensuring you can access this vital piece of business information quickly and efficiently.

Common Places to Look for Your EIN

When the question “where is my EIN number?” arises, the first step is to check common places where you might have previously recorded or received it. Often, the EIN is documented in official business paperwork or communications. Here are the primary places to investigate:

1. Your EIN Confirmation Notice (Form CP 575 or Form 147C)

The most direct way to find your EIN is by locating the original confirmation notice issued by the IRS when you first applied. This notice, officially known as Form CP 575, is mailed to you by the IRS shortly after your EIN application is approved. More recently, for online applications, the IRS may issue Form 147C, which serves a similar confirmation purpose.

This document is the official record of your EIN assignment and should be kept in a safe and accessible place. Look through your business files, especially those related to the initial business formation documents. It’s often filed with other important legal and tax documents.

2. Business Bank Account Documents

Banks require your EIN to open a business account. Therefore, your EIN should be documented in your bank account paperwork. Check your business bank account application documents, account statements, or any records related to setting up your business banking. Contacting your bank directly is also a quick way to ask for your EIN if they have it on file for your account.

3. Previously Filed Tax Returns

Your EIN is required on all federal tax returns filed for your business. If you have previously filed business tax returns (such as Form 1065, Form 1120, Form 1120-S, or Form 941), your EIN will be clearly stated on the first page of these documents. Reviewing copies of your past tax returns is a reliable method to find your EIN. These records are typically stored with other tax-related business documents.

4. Business Licenses and Permits

Depending on your business type and location, you may have obtained various business licenses or permits at the state, local, or federal level. Many of these applications require you to provide your EIN. Check copies of applications for business licenses, permits, or registrations that your business has obtained. Agencies that issued these licenses might also have your EIN on file, although accessing it might require direct contact.

What to Do If You Still Can’t Find Your EIN

If you’ve thoroughly checked all the common locations and are still unable to find your EIN, don’t worry. There are still ways to retrieve it directly from the IRS.

Contact the IRS Directly

The most definitive way to find your EIN if you’ve exhausted other options is to contact the IRS Business & Specialty Tax Line.

Here’s how to contact the IRS to find your EIN:

Phone: Call the IRS Business & Specialty Tax Line at 1-800-829-4933. The phone lines are open Monday through Friday, from 7:00 a.m. to 7:00 p.m. local time.
Be Prepared to Verify Your Identity: When you call, an IRS representative will ask you to verify your identity and authorization to receive the EIN. You will likely need to provide identifying information about your business, such as:
- Your business name and address
- Your business type (LLC, Corporation, Partnership, etc.)
- The name and Social Security number of the responsible party who originally applied for the EIN.
- Potentially, the date you originally applied for or received your EIN (if you remember it).
Authorized Individuals Only: The IRS will only release the EIN to individuals who are authorized to receive it. This typically includes the responsible party listed on Form SS-4 (Application for Employer Identification Number) or individuals with power of attorney.

Important Considerations When Contacting the IRS:

Patience is Key: Wait times on the IRS phone lines can sometimes be long, especially during peak tax seasons. Be prepared to wait, or consider calling during off-peak hours (early mornings or late afternoons).
Security and Privacy: The IRS prioritizes security. They will not provide your EIN via email or unsecure channels. Phone and mail are the official and secure methods for EIN retrieval.
No Online EIN Lookup Tool for Security Reasons: It’s important to note that the IRS does not offer a public online tool to look up an EIN for security reasons. Be cautious of any third-party websites claiming to offer an “EIN lookup” service, as these are often unreliable or potentially fraudulent. Direct contact with the IRS is the secure and recommended method.

Preventing EIN Loss in the Future

Once you’ve successfully located your EIN, taking proactive steps to prevent losing it again is wise. Good record-keeping practices can save you time and stress in the future.

Secure Storage of Your EIN Documents

Create a Dedicated Business Document Folder: Maintain a well-organized filing system for all your important business documents, both physical and digital. Have a specific section for tax-related documents, including your EIN confirmation notice.
Multiple Backups: Store your EIN confirmation notice and related documents in more than one secure location. This could include:
- Physical Copies: Keep a hard copy of your EIN confirmation notice in a secure filing cabinet at your business location.
- Digital Backups: Scan your EIN confirmation notice and save a digital copy in a secure, password-protected cloud storage service or on an encrypted external drive. Ensure you have multiple digital backups in case of data loss.
Share with Key Personnel (Securely): If you work with a business partner, accountant, or other key personnel who regularly need your EIN, provide them with a copy, but ensure they also understand the importance of keeping it secure.

Implement Robust Record-Keeping Practices

Digital Record Keeping Systems: Utilize accounting software or cloud-based document management systems to keep digital records of all essential business information, including your EIN.
Regular Document Review: Periodically review your business documents to ensure they are organized, up-to-date, and securely stored. This can also help you quickly locate your EIN or other information when needed.
Train Employees on Document Handling (If Applicable): If you have employees, train them on proper document handling procedures, emphasizing the importance of securely storing sensitive information like the EIN.

By following these steps, you can minimize the risk of losing your EIN in the future and ensure you can easily access it whenever required.

Understanding Your EIN – Quick Recap

While the primary focus here is on finding your EIN, it’s helpful to briefly revisit the essential aspects of an EIN to understand its importance and proper usage:

Who Needs an EIN? Generally, businesses need an EIN if they:
- Hire employees
- Operate as a corporation or partnership
- File certain types of business tax returns (like employment taxes or excise taxes)
- Operate a tax-exempt organization
When Do You Need a New EIN? You typically need to apply for a new EIN if your business structure or ownership changes significantly (e.g., changing from a sole proprietorship to a corporation, or a major change in ownership in a partnership or LLC). You generally do not need a new EIN if you only change your business name, business location, or responsible party.
EIN is for Federal Tax Purposes: The EIN is primarily for federal tax identification. However, it is also commonly used for various other business purposes, such as opening bank accounts, applying for licenses, and credit applications.
One EIN Per Business: Generally, a business entity should only have one EIN. If you believe you have multiple EINs or are unsure which one to use, contact the IRS to clarify.

Conclusion

Knowing “where to find my EIN number” is a crucial aspect of business management. While the EIN confirmation notice is the primary source, understanding alternative locations and methods to retrieve it from the IRS directly is vital. By implementing robust record-keeping practices and secure storage methods, you can prevent future instances of losing your EIN and ensure smooth business operations. Remember, your EIN is a key identifier for your business, and keeping it accessible and secure is an ongoing responsibility.
