How to Change Registered Mobile Number or Email ID on the GST Portal?

The steps to change the registered mobile number or email address on the GST portal are simple. There can be two ways to change these details, depending on the number of authorised signatories the business entity has.

Authorised signatory is the same person as the partner/promoter

Step 1: Log in to the GST portal and go to Services -> Registration -> Amendment of Registration Non-core Fields.

Step 2: Click on the tab ‘Promoter/Partners’. Click on the ‘Edit’ button under ‘Actions’, next to the authorised signatory, whose details you wish to change.

Step 3: Update the mobile number or email address, as applicable. Click on ‘Save’.

Step 4: An OTP will be sent to the mobile number, and email address entered. Enter the OTPs. The changes made will get reflected.

Step 5: Go to the ‘Verification’ tab. After entering the required information, tick the declaration checkbox, and submit the form with DSC/E-signature/EVC.

Note: If the EVC mode is selected, the OTP will be sent to the updated mobile number, which will need to be entered to complete the verification process.

Step 6: You will receive a confirmation message with the ARN number to track the status of the application once it is submitted. Once you receive a message saying ‘Changes Approved’, it means that the mobile number and email ID have been updated successfully.

Step 5: Wait for 15 minutes, and then log in to the GST portal. Go to Services -> Registration -> Amendment of Registration Non-core Fields.

Step 6: Go to the ‘Authorised Signatory’ tab, and deselect the previously authorised signatory as the primary authorised signatory.

Step 7: Select new authorised signatory as the primary authorised signatory. Confirm that the mobile number and email address provided are correct. An OTP will be sent to verify the same.
