Sachiya Mata is especially associated with communities from Rajasthan, including many Jain families. Her main temple is traditionally known at Osian / Osiyan in Rajasthan.

Among Paliwal Jains, family traditions may vary by lineage, region, or gotra, so some families may worship a different Kuldevi according to their own ancestral tradition.
