Can DU send my transcripts directly to institution like WES for Canada

Can DU send my transcripts directly to the concerned institution?
WES for Canada, in this case.

If I send them the RETURN envelope with the address of WES, will they send the transcript to them or they will send only to the applicant?
Please help.

I am not sure if Delhi University verifies the name and address on the return envelope.

I think that they can send it anywhere if the return envelope is correctly pre-paid.
They do post your return envelope directly to anywhere in the world.

So, it should fine if you place WES’s address on return envelope.

I would still suggest to first get the transcripts delivered to yourself, check and then send it to concerned institution to avoid lost mail issues.
