Hello there @Seller_UDZoTbNetWgd1

My name is CR and wanted to hop in here to see if I could provide you with some information. Here is a link to this Seller Central page that discusses how to find your NAICS code. I'd like to point out this section here:

Step 1: Identify your industry codes

Search the North American Industry Classification System to identify your six-digit industry code. These codes are used to classify business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. economy. NAICS codes are also used to provide small and large businesses standard determinations for specific industries.

To identify your NAICS code(s), go to http://www.census.gov/eos/www/naics:

1. In the search box on the top left side of the page, type the category that corresponds to your business.
2. Click Search to display a list of matching NAICS codes.
3. Choose the code(s) that best describes your business.

Please let us know on this discussion if you require additional assistance or you can always contact Seller Support with inquiries at anytime. Thank you for checking in with us on the Seller Forums and for choosing to sell on Amazon.

I hope you have a great rest of the week ahead!
