A Demat account can be opened as fast as within 72 hours if the KYC is verified and the documents submitted are correct.If the user chooses to update their KYC details during the account opening flow itself, then it has to be verified by the KYC Registration Agency (KRA) before the Demat account is opened as per SEBI guidelines. So, KRA may take up to 72 hours to verify the KYC details, which could be the reason for delaying the account opening process. If the account opening is delayed for more than 72 working hours, you can reach out to us at wecare@religareonline.com
