What Is an EIN and Why Is It Important?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to identify your business for tax and administrative purposes.

Mohave County is home to a diverse range of businesses, from tourism-based ventures near the Colorado River to manufacturing and logistics in Kingman. The county offers pro-business incentives and has a reputation for supporting local entrepreneurs.

Many banks in Mohave County, such as those in Bullhead City and Lake Havasu City, require an EIN before you can open a business account.

  1. Decide on Your Business Structure

    Confirm whether you’re registering as a sole proprietor, LLC, corporation, or partnership. This affects your EIN application.

  3. Choose Your Application Method

    • Online: The IRS offers a free EIN application portal, available to those with a legal residence or principal business in the U.S.
    • Fax or Mail: You can submit IRS Form SS-4 by fax or mail if you prefer paper filing or don’t have a U.S. SSN/ITIN.
