The Karnataka Government delivers online verification for Caste Certificates through the Nadakacheri / Seva Sindhu portal at [Link Provided Below]. The Caste Certificate is a government-issued document issued by the Tahsildar / Revenue Office to citizens belonging to Scheduled Caste, Scheduled Tribe, Other Backward Class, Most Backward Class, Denotified Tribe or other notified categories. Citizens, employers, educational institutions, scholarship boards and government recruiters verify the authenticity of any Caste Certificate issued in Karnataka by entering the application reference number, holder's name and date of issue. The verifier page returns issuance status, holder demographic data and the certificate's validity period. The service is integrated with the State CSC network so applications, downloads and physical print outs are available at every Common Service Centre across the State. Authentication is also possible via the QR code printed on each digitally-signed certificate.
