About this Validator
This tool validates Indian Aadhaar Numbers according to UIDAI requirements.
The validator checks if a given Aadhaar number follows the correct structure and verifies its check digit using the Verhoeff algorithm.
This validation only confirms if an Aadhaar number follows the correct format. It does not verify if the number is actually registered with UIDAI.
