When starting or growing your small business, it’s easy to focus on logos, websites, or social media—but what about the paperwork that builds your business behind the scenes?

At GreenStreet 360, we help small business owners lay a solid foundation, and that starts with understanding the power of three key tools: your EIN, DUNS Number, and Business Licenses.

Let’s break it down:

📌 EIN (Employer Identification Number)

Think of an EIN as your business’s Social Security number.

It’s issued by the IRS and is required for:

  • Opening a business bank account

  • Filing business taxes

  • Hiring employees

  • Building business credit

Even if you’re a sole proprietor, getting an EIN helps separate your personal and business finances—a must for long-term success.

📌 DUNS Number

A DUNS Number is a unique 9-digit identifier issued by Dun & Bradstreet. It tracks your business credit profile, which is crucial if you want to:

  • Apply for business credit cards

  • Get approved for funding or vendor accounts

  • Build credibility with lenders, suppliers, and even clients

Without a DUNS number, your business might not even show up in many commercial credit systems.

📌 Business Licenses

Depending on your city, state, and industry, you may need one or multiple business licenses or permits.

These licenses:

  • Keep your business compliant with local laws

  • Help you avoid costly fines or shutdowns

  • Give your customers confidence in your professionalism

No matter how small your operation, licenses help legitimize your business in the eyes of the law—and your customers.

Why It All Matters

These three tools are often overlooked, but they’re absolutely essential to growing a real, fundable, and legally sound business.

When you have your EIN, DUNS, and licenses in place, you’re not just running a hustle—you’re building a business that’s ready for credit, capital, and long-term success.
