HI,

EVEN I AM FACING THE SAME ISSUE YAAR NOW WHAT TO DO PLEASE HELP 

I HAVE SAME PROBLEM IN 2 PARTY OUT OF 10 FOR GST TRANS-1, BOTH HAVE IEC CODE, DOING IMPORT EXPORT, SO I THINK ONLY THOSE WHO HAVE IEC CODE THEY HAVE PROBLEM, NEED TO CONTACT DEPARTMENT ASAP.. THANKS

In case of TIN showing as invalid in Tran 1 kindly login to ur vat web and update ur pan then proceeds after some days it will be valid

 

This is due to wrong excise or service regitration while migrating to GST.
