How to Get an EIN for a Trucking Company

An EIN — Employer Identification Number — is the business equivalent of a Social Security Number. It’s issued by the IRS and identifies your trucking company for tax purposes, FMCSA registration, bank accounts, and broker paperwork.

You cannot operate as an interstate motor carrier under an LLC or corporation without one. Getting it is free and takes about 15 minutes.

What the EIN Is Used For

Once you have an EIN for your trucking company, it shows up on nearly every piece of paperwork you file:

• FMCSA registration. Your USDOT number and MC number applications require your EIN if you’re applying as a business entity.
• Business bank account. Banks require an EIN to open a business checking account in your company name.
• Broker W-9. Every freight broker you work with will ask for a completed W-9 form, which includes your EIN and business name.
• Tax filing. Your federal business tax returns — whether Schedule C, Form 1120-S, or a partnership return — all use the EIN.
• Employee hiring. If you hire drivers or office staff, you use the EIN for payroll taxes and Forms W-2.

What You Need Before Applying

The IRS application takes about 10–15 minutes if you have this ready:

Your entity type. LLC is the most common for new carriers. Know whether it’s a single-member LLC or multi-member LLC.

Legal name of the business. The exact name on your Articles of Organization or formation documents. Spelling matters — the EIN will be issued under this name.

Principal business address. Physical address where the business is located. Cannot be a PO box for the primary address.

Name and SSN of the responsible party. The IRS requires the name and Social Security Number of the person who controls the entity. For a single-member LLC, this is you.

Business start date. When you formed the LLC (or when you expect to start operating as a sole proprietor).

Primary business activity. For a motor carrier, this is typically “Transportation” with “Trucking” as the specific type.

How to Apply

1. Go directly to IRS.gov and search for “Apply for an EIN Online.” The official application is free and available Monday–Friday, 7 a.m. to 10 p.m. Eastern time.

2. Select your entity type. For most carriers: Limited Liability Company.

3. Answer the questions about your LLC: number of members, state of formation, responsible party details.

4. Specify the reason you’re applying. For a new business: “Started a new business.”

5. Complete the confirmation. At the end of the application, you’ll receive your EIN immediately on screen. Print or save this confirmation page — it contains your EIN and will serve as your initial confirmation document.

The IRS will also mail a confirmation notice (CP 575) to the address you provide. It arrives in 4–6 weeks. You don’t need to wait for the paper notice — your EIN is valid immediately.

Avoid Third-Party EIN Services

Search for “EIN application” online and you’ll find many paid services charging $50–$150 to “apply on your behalf.” They’re submitting the same free IRS application and marking it up.

Apply directly at IRS.gov. It’s the same application, it’s free, and you get your EIN the same day.

After You Have Your EIN

With your EIN in hand, the next steps are:

1. Open a business bank account. Your EIN, LLC formation documents, and operating agreement are what banks need. See Business Bank Account for Trucking.

2. Apply for your USDOT number. Through the FMCSA portal at portal.fmcsa.dot.gov. Have your EIN, business address, and vehicle information ready.

3. Apply for operating authority (MC number). Immediately after getting your USDOT number, if you need operating authority. See MC Number Guide.

4. Complete your broker W-9. Fill out IRS Form W-9 with your business name, EIN, and address. Keep a signed copy ready — brokers ask for it constantly.

EIN vs. Your Social Security Number

If you operate as a sole proprietor without an LLC, you can technically use your Social Security Number instead of an EIN for FMCSA and some broker paperwork. Most experienced owner-operators advise against this.

Your SSN is your most sensitive personal identifier. Sharing it on broker packets — which circulate to multiple people — creates unnecessary exposure. Get an EIN even if you’re operating as a sole proprietor. It’s free, it protects your SSN, and it keeps your business identity separate from your personal identity.

If You Change Your Business Structure Later

EINs are tied to entity type. If you:

• Convert from sole prop to LLC: New entity, new EIN needed.
• Add or remove LLC members: Depending on the change, a new EIN may be required.
• Convert LLC to corporation: New EIN needed.

The IRS guidance on when a new EIN is required is specific to your situation. If you’re restructuring, confirm with a tax professional before assuming your existing EIN carries over.

Frequently Asked Questions

Can I apply for an MC number before I have an EIN?

No. FMCSA requires an EIN for operating authority applications filed as an LLC or corporation. Sole proprietors can use a Social Security Number, but most carriers apply as an LLC and need the EIN first.

Is there a fee to get an EIN?

No. The IRS EIN application is free. Be cautious of third-party websites that charge for EIN filing — the IRS application at IRS.gov is the only official, free source.

What if I already have an EIN from a previous business?

EINs are permanent and don't expire. If you dissolved a previous business and are forming a new one, you typically need a new EIN for the new entity. If you're operating as the same entity under a different name, the EIN stays the same. Verify with the IRS if you're unsure.
