Issuing COVID-19 Vaccination Certificates in India
The Government of India launched the COVID-19 vaccination program in January 2021. The roll-out of the Co-WIN application was key to this. While the cloud-based platform covered all the major modules that a vaccination program of this scale should have, it lacked the digital credentialing feature that was critical to open up travel and economy amid the COVID-19 pandemic. DIVOC was integrated with Co-WIN in January 2021, making India the first country where the digital verifiable credentialing was implemented. Over 1.9 billion vaccination certificates have been issued in India so far.

Features and services
Certificate generation: A certificate is generated in real-time every time a person’s vaccination record is created in Co-WIN. Citizens get the latest dose certificate, which could be provisional, final, or the precaution dose. Two types of certificates are issued: domestic (age is mandatory) and international travel certificates (date of birth is mandatory). Further, DIVOC certificates (domestic) can be generated in 22 languages in India.
Certificate download: Besides Co-WIN, DIVOC’s certificate module has been integrated with Arogya Setu, Umang, and Digilocker, so that citizens can download their certificates after vaccination from any of these portals/apps by using their registered mobile number.
Certificate verification: DIVOC’s integration with CoWIN enables verification of the QR code-based vaccination certificates online by using DIVOC’s verification utility embedded within Co-WIN.
Updating certificates: This feature can be used by citizens if the name, age, gender, date of vaccination, or other details on their vaccination certificate are incorrect.
Revoking certificates: This feature is also used in India.
Analytics: DIVOC has set up a dashboard for India, which gives a snapshot of the total number of certificates issued, and accessed.
Reconciliation service: This service was introduced in India to resolve any initial (bulk) data entry discrepancy such as date of vaccination.
Standards used
The international certificates issued in India for citizens traveling abroad are based on the WHO-Digital Documentation of COVID-19 Certificates (DDCC) data specification.
