Quick answer: no, you don't need a UK company number to register

We get this question a lot from international businesses and sole traders, so the short answer: no, you don't need a UK Companies House number to register on AI Verified. The registry is global. We verify businesses using the national registry of the country you're registered in — Companies House for UK businesses, CIPC for South Africa, SEC/state registries for US businesses, and so on. If your country has a public business registry, we use that. If it doesn't, we use alternative verification methods. Sole traders and freelancers can also register. You don't need to be a limited company. The verification process is different (we verify your identity and domain rather than a company registration), but the result is the same: a machine-readable identity record with a forensic hash. If you're unsure whether your business type qualifies, the registration flow will tell you — it adapts based on your country and business structure.
