Offline format and checksum validation for the most common Indian identity and financial identifiers — PAN, Aadhaar, GSTIN, IFSC, and UPI ID — in a single, dependency-free library.
No API keys. No network calls. No third-party costs. Just instant, reliable validation you can drop into any onboarding, KYC, or data-entry flow to catch invalid and mistyped inputs before they ever reach a paid verification API.
These validators confirm that an identifier is well-formed and checksum-valid — they do not confirm that it exists or is linked to a real person, business, or active account. Genuine identity verification (Aadhaar OTP eKYC, PAN existence checks, bank penny-drop, GSTIN status) requires the relevant UIDAI / government / banking API. Use this library as a fast, free first line of defence in front of those paid services.
OutSystems 11 (Reactive, Traditional Web, and Service Actions). No platform extensions or external configuration required.
