Industry Intelligence Center · Updated: November 2025 · Reviewed by: SICCODE Research Team
When your growth strategy depends on reaching the right companies online, nothing is more valuable than a clean, verified list of company websites (domains) by industry. SICCODE’s website lists combine accurate SIC and NAICS classification with verified domains, enabling high-precision digital targeting, ABM, ad suppression, enrichment, and analytics. Whether you’re building retargeting audiences, mapping competitor ecosystems, or powering a data lake, verified domains are the backbone of modern B2B marketing.
What’s Included in a Website List

- Verified website/domain: Root domain and normalized URL
- Industry classification: Primary/secondary SIC & NAICS + industry description
- Firmographics: Revenue range and employee count (where available)
- Geography: Country, state/province, city, ZIP/Postal
- Lineage & freshness: Last verified date / data source references
