How can I update my six-digit NAICS code?
Update your business' NAICS code by filing an NAICS code change online.
Your NAICS code is a six-digit code used by federal statistical agencies to classify your primary business activity. The NAICS code is currently mandatory for annual report filings and it must also be included on formation documents. There is no fee to update your NAICS code.
If multiple NAICS codes apply to your business, please pick the one that most closely describes your primary business activity. NAICS codes are public and self-reported by businesses. We don't check the code you provide or tell you if another code is a better match for your business.
