How to Use Secretary of State Data to Find New Clients

2026-03-25 - 9 min read

What is Secretary of State Data?

Every business that formally registers as an LLC, corporation, or partnership files with their state's Secretary of State (SOS) office. This creates a public record that includes the business name, formation date, registered agent, entity type, and sometimes the business address.

Step-by-Step: Finding Clients

  1. Visit your state's SOS business search page (links on each state page on NewBizRadar)

  3. Filter by entity type if relevant (LLC, Corp, etc.)
  4. Export or note the business names and dates
  5. Research each business online to qualify them
  6. Reach out with a personalized offer
