Dear Candidate,

As per your query you have forgotten your control number so you will not be able to fetch your user id and password because in order to get back your username you have to put control number after you click on the username in the website of IGNOU. So, I am suggesting you send an email to IGNOU.

Email ID:registrarsrd@ignou.ac.in

Or you may call to them listed below the numbers of Delhi regions.

DELHI- 011-26990083, 011-26990082, 011-23392374, 011-23392376,011-23392377,011-25088939, 011-25088944

I hope they will surely solve your problem.
