# 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.

## Platform release version 

Since India was the first country to implement DIVOC, a component-wise release was done as there was no generic version available back then. Hence, the release versions are component-specific:

## Features and services

[**Certificate generation:**](https://divoc.digit.org/platform/divocs-verifiable-certificate-features-2.0/creating-a-divoc-certificate) 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:**](https://divoc.digit.org/divoc-demo/citizen-portal#2.-for-downloading-a-certificate) Besides Co-WIN, DIVOC’s certificate module has been integrated with [**Arogya Setu**](https://www.aarogyasetu.gov.in/)**,** [**Umang**](https://web.umang.gov.in/landing/)**,** and [**Digilocker**](https://www.digilocker.gov.in/)**,** so that citizens can download their certificates after vaccination from any of these portals/apps by using their registered mobile number.
