Changing depository from where eCAS is received

Good morning

I receive my eCAS from NSDL since I had first opened an account with them. However, my primary account is now at Zerodha.

As per SEBI regulations (Point 5 in this circular), I can choose which depository to get it from. I want to get it from CDSL.

Do i have to contact NSDL, CDSL or zerodha support for this? Grateful for any help

Checking this with the team, @tallerballer

Thanks Meher, I can proceed with it once I know whom to contact

Hi Meher, any updates?

Hey @tallerballer , Sorry for the delay. Let me touch base with the team once again. I’ll get back with an update quickly

Update from the team:

The client needs to give a request to both of his DPs to make his preference CAS flag changed to CDSL.

This request can be given by way of email from the registered email to DPs.

Thank you. It’s a very old demat account and there is no email etc in it.
So looks like it won’t be possible
