Vaccine Certificate Correction – Update Mobile Number, Name, Address

Vaccine Certificate Correction: Covid vaccination is still ongoing in India, with 90 percent of Indians fully vaccinated as of today, and beneficiaries who have been vaccinated against covid receiving a Vaccination Certificate. This certificate is proof that you received the dosage of the vaccine and is sent via a link to the beneficiary’s mobile number. By opening the link, you can obtain the COVID-19 Vaccination Certificate.

Vaccine Certificate Correction

When we are vaccinated under the GOI’s COVID Vaccination program, we are given a certificate that serves as verification that our immunizations have been completed. However, there are certain inaccuracies in that certificate, such as name, date of birth, mobile number, address, gender, and so on, which we must repair because it has now become a document that is used to get entrance into public areas.


So, for your knowledge, we are explaining how we can repair our incorrect facts while sitting at home. And you can do so by visiting, which is a certified website designed by the Ministry of Health and Family Welfare Department for the country’s immunization drive.
