Why a NAICS Search Is Important for Business Research

A NAICS search can be an extremely helpful tool for businesses of all sizes. By understanding the ins and outs of this type of search, businesses can better understand their own industry and find potential areas for growth.

Here are five key benefits of conducting a NAICS search:

1. Understand Your Industry

The North American Industry Classification System (NAICS) is used to classify businesses by industry. This system, created by federal statistical agencies, provides a common language that businesses can use to compare and contrast themselves with others in their field.

By understanding which North American Industry Classification codes apply to your business, you can get a better sense of the big picture when it comes to your industry. This knowledge can be extremely helpful when making strategic decisions about your business.

2. Qualify for Government Contracts and Business Grants

A NAICS code can help you determine if you qualify for a government contract or business grant. Some businesses with certain codes may qualify for government contracts whereas others might not.

3. Find Potential Areas for Growth

The NAICS system is constantly evolving. It's reviewed and updated every five years to reflect changes happening in the business world.

Take a look at the latest NAICS code version and see what new codes have been added. This is a great way to identify areas in which your business can expand its services or offerings.

4. Conduct Market Research

Businesses aggregate and use data from one sector or several industries to gain insights into the overall business economy. This helps them make better business decisions, like whether to enter a new market or pivot in a different direction.

5. Find New Business Partners

You can search for businesses that fall under your NAICS number to find potential business partners. What turns up will be companies that hail from the same sector or industry.

These new partners can offer up expertise, help when needed, and even partner with your business to help each other expand and grow.

What Is a NAICS Code?

A NAICS code or NAICS number is a 6-digit code used to classify every business type. The US Census Bureau uses the North American Industry Classification System for publishing statistical data related to every industry.

NAICS is used by small businesses and trade associations for the purpose of analyzing their own data.

Many businesses find it useful to use NAICS codes to track their own performance or compare themselves to similar businesses in specific industries.

NAICS is the first industry classification system to be used across all three North American countries (Canada, Mexico, and the United States). It is also the first to be used for statistical purposes at the North American level by the SBA government agency.

The NAICS revision process is an ongoing continuous effort to maintain the NAICS structure and keep it up-to-date with the rapidly changing structure of the North American economy.
