Reissuance Is Required

• Contact information, such as a mobile number or email, cannot be edited in an existing DSC.
  
• To update contact details, a new DSC must be applied for with the correct information.
  
• This is because certificate details are digitally signed and cannot be altered post-issuance.
  

Submit Fresh Application with Updated Information

• You must fill out a new DSC application for me, including the revised contact details.
  
• Provide necessary identity and address proof along with the updated mobile number or email.
  
• Verification will be done again as per the certifying authority’s process.
  

Revoke the Old Certificate

• After the new DSC is issued, the previous certificate should be revoked.
  
• This ensures that outdated or incorrect contact details are not linked to an active DSC.
  
• Revocation helps maintain security and compliance.
  

Verification of Updated Details

• The updated contact information is validated before the new DSC is issued.
  
• Video or OTP-based verification may be conducted as part of the process.
  
• Only after successful verification will the DSC be activated with new contact data.
  

Maintain Consistency Across Platforms

• Once reissued, the new DSC should be registered again on the relevant government portals.
  
• Ensure the same contact details are updated in portal user profiles for smooth integration.
  
• Keep the token or certificate file safe and updated in all required systems.
