- Search the exact legal name (or registration number) in the entity search and confirm the status shows active or in good standing.
- Match the registered name against the name on the contract or invoice; a different trade name should trace back to the same registered entity.
- Verify any trade or professional license in the licensing agency's own lookup, including status and expiration, not just that a number exists.
- For storefront or location-based work, confirm the local business license with the city or county clerk; it will not appear in statewide searches.
