Look up industry codes, confirm your classification, or build a targeted company or contact list backed by SIC and NAICS data.

Custom list refinement
Industry codes get the list started. Custom refinement helps find the right companies inside the market, so your list has better matches and less noise.
A NAICS or SIC code helps us find the right general market, like choosing the right neighborhood.
We create the list using the industry scope, location, company size, revenue, employees, and contact filters you choose.
When you need a sharper list, we can add custom rules to help keep better-fit companies and reduce records that do not match your goal.
Start with the plumbing industry code. Then refine the list around the type of plumbing companies you actually want to reach.
You may want commercial, industrial, municipal, emergency-service, drain-cleaning, mechanical, or specialty-service companies, while excluding residential-only businesses where possible.
Find Companies That Match My MarketHow custom refinement works
Basic list targeting starts with industry codes and standard business filters. Custom refinement is available when your target is more specific than the code itself.
Every buyer has a different target. One customer may want commercial plumbers, while another may want residential repair companies, suppliers, contractors, or specialty service providers.
It helps reduce noise. The goal is a cleaner list with more companies that look like your ideal prospects and fewer records that only loosely fit the industry.
