The process to update your registered mobile number or email address on the GST portal is simple. There are two methods to make these changes, depending on how many authorised signatories your business has.
When the authorised signatory is the same as the partner or promoter:
Step 1: Log in to the GST portal and navigate to:
Services → Registration → Amendment of Registration (Non-core Fields).
Step 2: Go to the ‘Promoter/Partners’ tab. Then click on the ‘Edit’ button under the ‘Actions’ section next to the authorised signatory whose details you want to update.
Step 3: Enter the new mobile number or email address, as required, and then click on ‘Save’.
Step 4: You will receive OTPs on the new mobile number and email address. Enter these OTPs to verify. Once verified, the changes will be updated successfully.
Step 5: Go to the ‘Step 5: Go to the ‘Verification’ tab. Fill in the required details, tick the declaration checkbox, and submit the form using DSC, E-signature, or EVC.
Note: If you choose the EVC option, an OTP will be sent to the updated mobile number. Enter this OTP to complete the verification.
Step 6: After submitting the form, you will receive a confirmation message along with an ARN number to track your application status. Once you see the status ‘Changes Approved’, it means your mobile number and email ID have been updated successfully.
When the authorised signatory is different from the promoter or there are multiple authorised signatories:
Step 1: Log in to the GST portal and go to:
Services → Registration → Amendment of Registration (Non-core Fields).
Step 2: Go to the ‘Authorised Signatory’ tab and click on the ‘Add New’ button.

Step 4: Go to the ‘Verification’ tab, fill in the required details, tick the declaration checkbox, and submit the form using DSC, E-signature, or EVC.
Step 5: Wait for about 15 minutes, then log in again to the GST portal and go to:
Services → Registration → Amendment of Registration (Non-core Fields).
Step 6: Open the ‘Authorised Signatory’ tab and remove the previous person as the primary authorised signatory.
Step 7: Select the new authorised signatory as the primary one. Check that the mobile number and email ID are correct. You will receive an OTP for verification.
