A human decides whether each page is published, but individual facts — addresses, contact details, and whether a company operates in a given location — are not independently fact-checked by us. Where you see a “Verified” badge, it means multiple independent sources agreed, not that we personally confirmed it. Companies open, close, relocate, and change contact details without always updating public records, so treat everything here as a starting point, not a confirmed source.
