In South India, Jain surnames vary by region, language, and community. Common Jain surnames include:

• Shah
• Kothari
• Jain
• Bhandari
• Dugad
• Sanghavi / Sanghvi
• Lunia / Lunia
• Mutha
• Mandal
• Patel
• Agarwal or related merchant-family surnames in some communities

In South India, many Jains also use village names, family names, or caste/community identifiers instead of a fixed “Jain” surname. In some places, surnames may reflect trade, lineage, or place of origin rather than religion alone.

If you want, I can also give:

• Gujarati Jain surnames
