Same gst no but with different trade name

I had purchased goods from "sakambari silk mills pvt ltd." & Vallabhi Prints both firms are having same GST No. when being asked i got replied that Vallabhi Prints Is subsidiary of shakambari silk mills pvt ltd.

I want to know how will i match my 2A as on checking on GST portal only main firm name is being displayed.
