In Jain tradition, Sauripura is described as a place associated with Bhagwan Neminath and the Yadava line, in the Dwarka–Saurashtra region.

So, yes, it is generally understood to be in the Dwarka region, but it is not always identified as the exact same modern village or town called “Dwarka” today. The ancient Sauripura is usually treated as a historical place near Dwarka, not necessarily the present city itself.

In short: Sauripura was in the Dwarka area, but it is not simply “Dwarka” in the modern sense.
