PAN represents permanent Account Number issued by the Indian Income Tax Department. It supports identity, tax, bureau, and KYC verification. Treat it as sensitive information and mask where required. In credit appraisal, it supports identity checks, eligibility validation, regulatory classification, legal due diligence and audit readiness. The field should be supported by documentary evidence and should remain consistent across application data, KYC records and regulatory reporting. For example, PAN is used to match income-tax records, bureau data, GST registrations and borrower identity across systems. It matters because incorrect classification or missing evidence can create regulatory risk, wrong scheme treatment, audit exceptions or delayed approval. The common caution is to rely on verified documents and current regulatory rules rather than informal borrower declarations or outdated master data.
