Documents required for Trade Name Change of Proprietorship in GST

This discussion addresses the confusion surrounding the documents required for changing the trade name of a proprietorship under GST. The original poster faced rejection after submitting an electricity bill, and the tax authorities requested a 'TP Document'. Other users suggest this might refer to a Gumasta license or rental agreement/property registry, depending on the business premises. The core issue is identifying the correct documentation for the GST portal's 'change of core fields' application.
