"My Aadhaar card and UDID card were issued in 2021. Should I now get the KYC done for my UDID card? What is the period or validity of the KYC or e-KYC after a UDID card is issued? Please provide information about this. I created my UDID card in 2021. My medical condition was already registered, and based on that, the UDID card was made in 2021. Now I would like to know whether the e-KYC period of the UDID card starts from the time it is created or if it needs to be done again only after 5 years? Please provide complete information about the KYC and e-KYC rules — so that others like me can also benefit from the information."
