If you need to confirm the authenticity of a Residence or Nativity Certificate issued by the Tamil Nadu Revenue Department, you can use the e-Sevai portal at Visit tnesevai.tn.gov.in. This online service allows citizens, employers, educational institutions, and government recruiters to verify certificates by entering the application reference number, certificate holder’s name, and date of issue. The portal will display the certificate’s issuance status, demographic details, and validity period. You can also verify certificates using the QR code printed on each digitally-signed document. For those without internet access, verification and printouts are available at any Common Service Centre (CSC) across Tamil Nadu.
