I received a mail informing about PAN Mismatch. But it does not give the exact details about mismatch. Is it required to use the exact same address as given in PAN?(i know that name should match with Pan data)
I also came across same error, I first punched name as per id proof other tha PAN,
so I corrected it by entering same name and father name as pan card then error got resolved,
or you can log in on Income tax site, look for name profile tab, and punch same on GST site
