# 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: | Components | Release Version | | ---------------------------------------------------------------------------------------- | --------------- | | Certificate generation services: dockerhub/divoc-certification-ack | 1.0.16 | | Certificate generation services: dockerhub/certificate\_processor | 1.0.16 | | Certificate generation services: dockerhub/certificate\_signer | 1.0.22 | | Certificate generation services: dockerhub/vaccination\_api | 1.0.27 | | Certificate generation services - Commonly-used component: dockerhub/registry | 1.0.19 | | Certificate generation services - Commonly-used component: dockerhub/caching-dash-server | 1.0.20 | | Verification component: dockerhub/verification | 1.0.29 | | Certificate reconciliation services: dockerhub/reconciliation | 1.0.3 | | Fetch certificate services: dockerhub/digilocker\_support\_api | 1.0.59 | | Fetch certificate services: dockerhub/registry | 1.0.19 | | Dashboard: dockerhub/analytics\_feed | 1.0.17 | ## Features and services [**Certificate generation:**](/platform/divocs-verifiable-certificate-features-2.0/creating-a-divoc-certificate.md) 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/products/pages/ZewaVGl8Ggsp0imFvYlb#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. ![](/files/wGM35HfkB4pfGhbc7ujH) [**Certificate verification:**](/platform/divocs-verifiable-certificate-features-2.0/verifying-a-divoc-certificate.md) DIVOC’s integration with CoWIN enables verification of the QR code-based vaccination certificates [**online**](https://verify.cowin.gov.in/) by using DIVOC’s verification utility embedded within Co-WIN. ![](/files/6IvpU0hJhVuRhHTnITP5) [**Updating certificates:**](/platform/divocs-verifiable-certificate-features-2.0/updating-a-divoc-certificate.md) 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:**](/platform/divocs-verifiable-certificate-features-2.0/revoking-a-divoc-certificate.md) This feature is also used in India. [**Analytics:**](/divoc-demo/analytics.md) DIVOC has set up a [**dashboard**](https://stats.cowin.gov.in/public/dashboards/HT9vhThnsXTQcuLUrFprMz97moerYPnRqtf7WRPn) for India, which gives a snapshot of the total number of certificates issued, and accessed. ![Note: These are April 19, 2022, numbers](/files/O0mBjA8REwTzQBGJ7xp1) **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)**](https://www.who.int/publications/i/item/WHO-2019-nCoV-Digital_certificates-vaccination-2021.1) data specification.
