I have registered in NSR, but by mistake DOB in incorrect. But it is not able to modify/change DOB. Can you please help with this problem.

This is what one of the FAQs on the site says:

#-Link-Snipped-#

In case you missed-out some information while doing registration or made some errors these can be completed / corrected after registration. In case you need to enter new information such as an additional qualification, change in address or employment it can always be added after registration.

Your details can be updated / changed only by you. Such modifications can be done by authenticating the modifications with a password different than your login password.  Whenever there is a change in your details, the system will send you an alert mail at your email id registered in the database.

However, information which gets verified or which is under the process of verification cannot be edited. 

                

I think #-Link-Snipped-#‍  is talking about registration somewhere else. Could you please clarify? 

I have registered in National skills registry, modifications can be done. But it's showing that DOB can't be changed.

#-Link-Snipped-#‍ - the NSR website mentions the following about changing date of birth (dob) or mother maiden name etc -

I have committed an error during registration in updating Gender or Mother.s Maiden Name or Date of Birth. How should I correct the same?

NSR provides you the facility to make the required changes in your profile with respect to Gender/Mother.s Maiden Name /Date of Birth. You have to fill up the Data Value Change form available in Knowledge Professionals-Useful download. Visit the POS office with duly filled-in form along with Identity proof and requisite fees.(Refer Knowledge Professionals- Fee Structure for details).

Thanks a lot for the information ?
