If you need to confirm the authenticity of an Income Certificate issued by the Goa Revenue Department, you can use the Goa Online portal at Visit goaonline.gov.in. This service is open to citizens, employers, educational institutions, scholarship boards, and government recruiters. To verify a certificate, simply enter the application reference number, the certificate holder's name, and the date of issue. The portal will display the certificate's issuance status, demographic details of the holder, and its validity period. You can also verify certificates using the QR code printed on each digitally-signed document. For those who prefer in-person assistance, verification and printouts are available at any Common Service Centre (CSC) across Goa.
