The UMGC Library cannot answer questions or provide direct assistance related to tax, personal businesses, or government contracting information.

Please contact the Census Bureau for assistance in determining your NAICS code for your personal business. You can call them at 1-888-756-2427 or email them at

The NAICS Association has a website with a help page for finding your NAICS code here: 
How can I determine the correct NAICS code for my business? 

If your business is not listed, try searching on the keyword for the industry your business is in. We also have a help page:
How do I find NAICS codes

Finding NAICS codes is not an exact science -- sometimes you have to "guess" based on the industry that most closely describes your business.
