What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business, used to identify it for tax purposes. Even if you're a solo marketer, an EIN can offer significant advantages.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your marketing business structure requires an EIN. LLCs with multiple members, corporations, and businesses with employees generally need one. Even single-member LLCs in Arizona may benefit from having an EIN.
  2. Gather Required Information: Collect all necessary information, including your business name, address, the responsible party's name and Social Security number (or ITIN), and the reason for applying for the EIN.
  3. Complete the Online Application (Form SS-4): Access the IRS website and complete the online EIN application (Form SS-4). The online application is the fastest and most efficient method.
  4. Submit Your Application: Carefully review your completed Form SS-4 and submit it electronically through the IRS website.
  5. Receive Your EIN: Upon successful submission, you will receive your EIN immediately online. The IRS will also send you a confirmation letter (Form CP 575) via mail.
  6. Keep Your EIN Safe: Store your EIN in a secure location and avoid sharing it unnecessarily. It is a critical piece of information for your business.
