GLOBAL TIN VALIDATOR
Validates Tax Identification Numbers against country-specific regex rules — 100% offline. Upload the rules file first (⚙️ tile in Bulk Upload); it is required for both single and bulk validation.
1 · Load rules
Upload the JSON rules file in the Bulk Upload section — needed for both modes.
2 · Single check
Pick TIN type, enter a 2-letter country code and a TIN, then validate instantly.
3 · Bulk check
Upload a CSV or Excel file with Country Code, TIN Type and TIN columns, run, then download results (CSV / XLSX).
Outcomes: Valid · Invalid · No Rule / Regex N/A (couldn't be checked). TIN Type must be Individual or Entity.
