If you need to confirm the authenticity of a Kerala Domicile Certificate, you can use the e-District Kerala portal at Visit edistrict.kerala.gov.in. This online service lets you check certificates issued by the Kerala Revenue Department by entering the reference number, certificate holder's name, and date of issue. The portal will display the certificate's issuance status, demographic details, and validity period. Verification is open to citizens, employers, educational institutions, scholarship boards, and government recruiters. You can also scan the QR code printed on each digitally-signed certificate for instant authentication. For those without internet access, verification and printouts are available at any Common Service Centre across Kerala.
