What a bulk check does
You upload a list of IDNOs — from a file or pasted in — and get each company's current name, legal form, status in the State Registry, registration date and main activity. What would mean opening a hundred profiles one by one happens in a single pass.
Numbers absent from the registry are listed separately rather than buried: usually a one-digit typo or a company struck off long ago, and those are exactly the ones worth a second look.
