Verifies PAN card number format and structure locally. Extracts the taxpayer category from the PAN code — Individual, Company, Trust, etc. No data is sent to any server.
Validates UPI ID format rules for all popular handles (@paytm, @okhdfcbank, @ybl, @sbi, @upi, @axl, @icici) and generates UPI payment QR codes with merchant name and amount. All local processing.
Generate fake credit card numbers with valid formats including Visa, Mastercard, Amex, and Discover. All numbers pass Luhn algorithm validation. Everything runs locally in your browser — nothing is uploaded.
Validate API key format including length checks, character set validation, prefix verification, and entropy analysis.
The 12-digit number must satisfy the Verhoeff checksum (last digit validates the first 11) and format rules — first digit 2–9, no obvious patterns like 11 repeated digits. The tool checks all of these instantly.
No. Validation proves the number is well-formed, not that UIDAI issued it to the holder. For onboarding or KYC, always verify against UIDAI e-KYC or masked-Aadhaar XML — never trust format alone.
A version showing only the last 4 digits (XXXX-XXXX-1234), downloadable from myAadhaar. Share masked copies wherever full numbers aren't legally required — it limits exposure if the copy leaks.
Never publish full numbers, email them unencrypted, or store them in spreadsheets without need. Collect only with consent and a stated purpose, per the Aadhaar Act.
No. Validation runs entirely in your browser via the Verhoeff algorithm. Numbers never leave your device.
