In my matric certificate name is spelt as" shambhoo kr Sahani", whereas in my service record it is " shambhu Kumar Sahani". I am employed since last 20 years. Is it a cause of concern,if yes, how to rectify it?
You have not stated what is your correct name in the query. Better to get a gazette notification regarding your correct name. For Gazette notification, you have to apply through the Tahsildar concerned.
Do not unnecessarily get disturbed with trivial things. Matric certificate is only a qualification certificate, and after 20years it is not going to help or obstruct you in future. Once you have correct AADHAR, there is no problem in future.
