While some organisations have objected to the circular, CBSE said the move is aimed at making use of information communication technology tools to improve communication among its various stakeholders.
Schools were asked to submit the information by August 25.
A few schools in Rajasthan objected to the order, fearing that personal information of students could be used for non-academic activities.
In its circular, CBSE has said, "Having mobile number and email details will not only facilitate the candidate to have timely and latest updates but will help the board also in advance planning and estimation relating to examinations."
Officials in the HRD Ministry said the information would be kept strictly confidential.
The controversy comes in the run up to the Prime Minister's live address to students on Teacher's Day. The HRD Ministry has embarked on an unprecedented exercise to make the programme a success.
CBSE has requested schools to make arrangements to "assemble" the children so that they may view the Prime Minister's address.
It said suitable arrangements will need to be made to enable children stay from 2:30 pm to 5:00 pm in the school on September 5.
A report on the arrangements made by your school and the number of students who are likely to be covered may be sent to the CBSE, it requested the schools.
