Update Mobile Number & Email on GST Portal

Businesses can easily modify their registered mobile number or email address on the official GST portal. The process varies based on whether the authorized signatory is also a partner/promoter or if there are multiple signatories involved.

When the Authorised Signatory is also the Partner/Promoter

If the authorized signatory is also a partner or promoter, follow these steps to update contact details:

1. Access the official GST portal and navigate to ‘Services’ -> ‘Registration’ -> ‘Amendment of Registration Non-core Fields’.
2. Select the ‘Promoter/Partners’ tab. Locate the authorized signatory you wish to modify and click the ‘Edit’ button under ‘Actions’.
3. Enter the new mobile number or email address and click ‘Save’.
4. One-Time Passwords (OTPs) will be sent to both the updated mobile number and email address. Input these OTPs to confirm the changes.
5. Proceed to the ‘Verification’ tab. Provide the necessary information, check the declaration box, and submit the form using DSC (Digital Signature Certificate), E-signature, or EVC (Electronic Verification Code). Note: If EVC is chosen, an OTP will be dispatched to the newly updated mobile number for verification completion.
6. Upon successful submission, an ARN (Application Reference Number) will be generated, allowing you to monitor the application’s status. The mobile number and email ID are successfully updated once a ‘Changes Approved’ message is received.

When the Authorised Signatory Differs from the Promoter or Multiple Signatories Exist

If the authorized signatory is not the same as the promoter or if there are multiple authorized signatories, follow these revised steps:

1. Log in to the GST portal and navigate to ‘Services’ -> ‘Registration’ -> ‘Amendment of Registration Non-core Fields’.
2. Access the ‘Authorised Signatory’ tab and click ‘Add new’.
3. Input the details of the new authorized signatory, including the email address and mobile number you intend to use, then click ‘Save’.
4. Proceed to the ‘Verification’ tab. Fill in the required details, accept the declaration, and submit the form using DSC, E-signature, or EVC.
5. After approximately 15 minutes, log back into the GST portal and return to ‘Services’ -> ‘Registration’ -> ‘Amendment of Registration Non-core Fields’.
6. In the ‘Authorised Signatory’ tab, deselect the previous primary authorized signatory.
7. Designate the newly added signatory as the primary authorized signatory. Verify the accuracy of the mobile number and email address; an OTP will be sent for confirmation.
8. Conclude the verification process as previously outlined in Step 5 of the first scenario.
9. Upon submission, an ARN will be issued for tracking. The contact details are successfully updated once a ‘Changes Approved’ message is received.
