Has anyone received Osmania University transcripts applied online ?

The Online Service is used to submit applications requesting for certificates and transcripts. After submission, you should visit with your ID proof, or Aadhar Card, about 15–25 days later. 

You will see your name on top of the envelope, it will be there for verification, along with your date of birth. Once you approve it, the managing staff will put it in an envelope and put a seal. 

Just be patient and have your IDs at hand.
