When your growth strategy depends on reaching the right companies online, a verified website list by industry gives you a cleaner and more dependable starting point.

SICCODE.com website lists combine verified domains with structured NAICS and SIC classification so teams can support digital targeting, ABM, suppression, enrichment, and analytics with better precision and stronger business context.

What Is Included in a Website List

A professional website list is more than a spreadsheet of URLs. It is a structured business dataset built around company identity, verified domains, classification, and usable segmentation fields.

  • Company identity: legal business name and DBA information where available.
  • Verified website or domain: root domain and normalized URL structure for cleaner company-level matching.
  • Industry classification: verified NAICS and SIC coding with industry description support.
  • Firmographics: revenue range and employee size where available.
  • Geography: country, state or province, city, and ZIP or postal fields.
  • Freshness and lineage: last verified timing and source-related references where applicable.
