Once you are in the Account Details section, locate the field for the mobile number. Click on the ‘Edit’ or ‘Update’ button next to it.

To change your mobile number in the vaccine certificate using the AAROGYA SETU APP, follow these detailed steps. First, open the AAROGYA SETU APP on your smartphone. Ensure you have the latest version of the app installed for a seamless experience. Once the app is open, navigate to the Profile section, usually located at the bottom right corner of the home screen.

For direct changes to the vaccine certificate, you may need to visit the Cowin portal or contact the relevant authorities. Nonetheless, keeping your AAROGYA SETU profile updated is a crucial step in this process.

Visit Vaccination Center: Provide new number to staff for manual update in the system
If you need to update your mobile number on your vaccine certificate, one of the most straightforward methods is to visit the vaccination center where you received your doses. This approach ensures a manual update directly in the system, which can then reflect on your certificate. Start by identifying the specific vaccination center where you were inoculated, as this is typically the only location authorized to make such changes. Once you have confirmed the center, plan your visit during their operational hours to avoid any inconvenience. It’s advisable to call ahead and inform them about your intention to update your mobile number, as some centers may require prior notice or have specific procedures in place.
Upon arriving at the vaccination center, head to the registration or help desk and clearly communicate your purpose. Provide the staff with your current details, including your name, date of birth, and the mobile number currently linked to your vaccine record. Be prepared to show identification documents such as your Aadhar card, voter ID, or any other government-issued ID to verify your identity. This step is crucial to ensure that the update is made to the correct record and to maintain the integrity of the vaccination database.
After verification, inform the staff about the new mobile number you wish to update. Ensure the number is accurate, as any errors could lead to further complications. The staff will manually update the system with the new number, which may take a few minutes depending on the center’s procedures. During this time, you may be asked to wait or return later to confirm the update. It’s important to remain patient and cooperative, as the staff are handling multiple tasks and ensuring accuracy is paramount.
Once the update is completed, request the staff to verify the change by checking the system or generating a sample certificate. This step ensures that the new mobile number has been correctly recorded and will reflect on your official vaccine certificate. If everything is in order, the updated details should sync with the national vaccination portal, and you should receive any future communications, such as booster dose reminders, on your new number.
Finally, before leaving the vaccination center, ask for a confirmation message or email if available, as this serves as proof of the update. In some cases, the changes may take a few hours or days to reflect on the Cowin portal or your vaccine certificate. If you encounter any issues or delays, don’t hesitate to follow up with the center or contact the Cowin helpline for assistance. Visiting the vaccination center for a manual update is a reliable method to ensure your mobile number is correctly changed in the system.

Correct Certificate: Ensure updated number reflects in the downloaded vaccine certificate
After updating your mobile number on the Cowin portal, it's crucial to verify that the changes are accurately reflected in your downloaded vaccine certificate. This ensures the document remains valid and up-to-date for all official purposes. Here’s how to ensure your updated mobile number appears correctly on the certificate.
Step 1: Download the Updated Certificate
Once you’ve successfully changed your mobile number on the Cowin portal, the next step is to download the revised vaccine certificate. Log in to the Cowin portal or the Aarogya Setu app using your new mobile number. Navigate to the "Certificate" section and download the latest version of your vaccination certificate. If using the Cowin website, click on the "Download Certificate" option next to your vaccination details. Ensure you have a stable internet connection to avoid any download errors.
Step 2: Verify the Mobile Number on the Certificate
After downloading the certificate, open the PDF file and carefully check the mobile number listed under your personal details. The number should match the updated mobile number you entered during the correction process. Pay close attention to the digits to avoid any discrepancies. If the certificate still shows the old number, it indicates that the update was not successfully applied, and you may need to repeat the correction process.
Step 3: Cross-Check with Cowin Portal
To further confirm the accuracy, log in to the Cowin portal again and verify the mobile number associated with your account. Go to the "Account Details" or "Profile" section and ensure the displayed mobile number is correct. If the portal shows the updated number but the certificate does not, try downloading the certificate again after a few hours, as there may be a delay in updating the document.
Step 4: Contact Support if Issues Persist
If the updated mobile number still does not reflect in the downloaded certificate despite following the above steps, reach out to the Cowin helpdesk or customer support. You can raise a query through the Cowin portal, Aarogya Setu app, or by calling the helpline number. Provide your reference ID, vaccination details, and a screenshot of the issue for quicker resolution. The support team will assist in rectifying the error and ensuring your certificate is correct.
Step 5: Keep Both Versions Safe
Once the updated mobile number is correctly reflected in the certificate, save both the old and new versions of the document for future reference. While the old certificate is no longer valid, keeping it can help in case of discrepancies or verification needs. Store the updated certificate securely, as it is a vital document for travel, workplace requirements, and other official purposes.
By following these steps, you can ensure that your vaccine certificate accurately reflects your updated mobile number, maintaining its validity and reliability.
