Hello there, hope you are doing good!

I would like to tell you that the control number is generated after you submit the application form for IGNOU. If you have not received it I suggest you contact the IGNOU admissions department to update you and generate your control number. I am attaching the email id where you can send an email about your missing control number and the IGNOU department will be able to help you.

onlineadmission@ignou.ac.in (mailto:onlineadmission@ignou.ac.in?)

Hope you found this answer helpful.

Good luck for your future!
