Overview

The Company CIN Lookup API returns the essential identity of any Indian company from its Corporate Identity Number (CIN): legal name, registration status, incorporation date, company type, registered office and Registrar of Companies. It is sourced from MCA records and refreshed continuously, making it the fastest way to confirm a company exists and pull its headline details into onboarding, KYB, lead enrichment or due-diligence flows.
