Hi

You must have got an email from IGNOU after registration and payment of fees with all the details including programme code and enrollment no. Check the email registered with ignou. Then go to https://admission.ignou.ac.in/changeadmdata/admissionstatusnew.asp in ignou official website and enter enrollment no and select the programme code you enrolled for from the drop down list.

This is how an email from them looks...
