Pahadiya and Pandya are not Jain sect names. From the names alone, I cannot reliably tell whether a family is Digambara or Śvetāmbara. In Jainism, the main divisions are Digambara and Śvetāmbara, and sect identity is based on Jain tradition and practice, not just a surname. ( jainpedia.org)
Explanation
So if you saw these as people’s names, they are more likely family surnames than a specific Jain “type.” To identify the Jain sect, you would usually need the family’s religious tradition or community background. ( jainpedia.org)
Takeaway
Surname does not तय sect in Jainism. The important Jain divisions are Digambara and Śvetāmbara. ( jainpedia.org)
