    The mobile and e-mail id registered at the time of obtaining TRN can only be changed by visiting jurisdictional office by filling an application physically. This would be normally be the jurisdiction of service tax/excise. There is no option in online to change authorized signatory’s no & e-mail id.

    GSTN will enable non core amendment by end of Sep 17 or 1st Week of Oct 2017 till then, the same cannot be filed. For proprietor you can use Authorized Representative option.

    No, its not working. It says Aadhaar Number & PAN already exists while Adding new Authorised Signatory. Secondly there is no help on the portal for this issue nor replies received for any resolution sent against queries on helpdesk and moreover there is no limitation on time. Time limit is only applicable to the Registration holders.

    I think this is not the right way to do it,

    You can simply change the contact and email ID mention for the primary contact person without adding secondary person .

    Further to add other person you to get NOC and attach his photo also. No need to take this lengthy and wrong route where the person is same and we just want to edit mobile no. and email ID
