Sir it means that your GSTIN Number ( GST Registration ) has been Cancelled by the GST Proper Officer on Suo-Motto Basis ( i.e. own will / wish ) because of the grounds mentioned under Section 29(2) clause (a) to (e) of the CGST Act 2017.
For example, if you have not filed your GST Returns for a continuous period of SIX MONTHS [ Section 29(2) clause (c) of the CGST Act 2017 ], then the Proper Officer has the power to cancel your GST Registration on a suo-motto basis.
Yes, You can revoke your old GSTIN Cancelled by the GST Proper Officer on Suo-Motto Basis as per processes mentioned by Mr. Jacinthamary. No need to apply new.
