Hey

DU SOL ROLL NO' and 'BAR CODE' is only provided on your identity card (ID).Without the roll number or barcode, you will not be allowed to login on the portal. But if you have lost your id card then here are the steps through which you can recover your roll no and barcode.

• Download SOL application on your Phone .
• Login with help of your SOL roll no. + registered mobile number.
• Student will receive One time password (OTP) .
• Put OTP in application and you are in.
• Click forget option . You can see all options related to your SOL . For eg. Barcode, Examination Roll no. , Results, enrollment no. Etc.

You can contact to the college authority regarding this because you dont have the registered mobile number. The process of getting SOL ID is School of Open Learning, Delhi University facilitates an SOL Login page with the start of the admission process. During the registration process, the student has to generate the DU SOL Login Student/Candidate login Id, and after the last date notified by the School of Open Learning, University of Delhi, no changes will be entertained.

I hope this helps.
