Hello, I am Ashok Kumar from Yamunanagar, Haryana. Regarding the question about changing the date of birth on the Swavalamban/UDID portal, the date of birth on a UDID card is generally based on the information provided in your official documents, especially your Aadhaar card and medical records. If your date of birth is incorrect, first get it corrected in your official documents. Once all documents show the correct date of birth, you can request an update to your UDID records. If the correction is related to medical records, you may need to contact the medical authority that issued the documents and apply for the correction through the proper process.
