Hello, I am Himant Das from Dumka, Jharkhand, and I am 100% visually impaired. If you want to apply for a Railway Concession Pass, you must have at least 90% visual disability and a UDID card. Required documents include an Aadhaar card, mobile number, UDID card, and one valid address proof such as a PAN card or Voter ID. This pass is intended for visually impaired persons.
