What Is a NAICS Code?

NAICS stands for North American Industry Classification System. It’s a 6-digit code system created by the U.S., Canada, and Mexico to classify businesses by industry.

For example:

  • 722513 – Limited-Service Restaurants

  • 541511 – Custom Computer Programming Services

  • 531210 – Offices of Real Estate Agents and Brokers

Instead of writing “I own a small software company that builds websites,” you simply use 541511. That code tells the government, lenders, and researchers exactly what you do.

Why NAICS Codes Are Important

You might wonder: “Why should I care about some 6-digit number?”

Here’s why NAICS codes matter:

  1. Government Contracts – Many federal contracts are industry-specific, so having the right code makes you eligible.

  2. Business Loans & Grants – Banks and government agencies often check your code before approving funding.

  3. Market Research – Companies use NAICS codes to analyze competitors and industry trends.

  4. Tax Purposes – The IRS uses NAICS codes to understand your type of business activity.

  5. Online Directories – Many B2B platforms list businesses by NAICS codes, making it easier to get discovered.

In short: your NAICS code defines your business identity on paper.
