Gst no. for normal and composition dealer

Yes we can. Click here to search taxpayer details using GSTIN. One of the details is 'Taxpayer type', which will show you whether the supplier is registered under the regular scheme or composition scheme.

Alternatively, there's another way that you can find here. You might want to select 'Opted In' and enter the GSTIN to confirm whether the supplier has opted for composition scheme.

Hope this helps.
