India

Taggun’s core receipt and invoice extraction is available for documents from India. Which optional fields and country-specific results are returned depends on the endpoint, request parameters, account settings, and submitted document. Country-specific results may be omitted or returned without a usable value. For currency, date format, language, and tax-system context, see Supported Countries & Languages.

GSTIN Validation

Taggun validates the GSTIN (Goods and Services Tax Identification Number) detected on receipts and invoices:

• Format validation — ensures the GSTIN follows the prescribed 15-character structure (e.g. XXABCDE1234F1ZX), where:
  • "XX" is the state code
  • "ABCDE1234F" represents the PAN (Permanent Account Number)
  • "1" is the entity code — the registration number for that PAN within the state
  • "Z" is a fixed default letter
  • "X" is the check digit

Format and check-digit validation catches mistyped or malformed GSTINs before they reach your records.

When available, the detected merchant GSTIN is returned at merchantTaxId.data. This validation checks the documented GSTIN structure; it is not a tax-authority registry lookup or a document-compliance determination.

Core extraction can also return a tax amount shown on the document at taxAmount.data, when available. This is generic extraction of the printed value, not an India-specific GST calculation or tax-rule determination.
