Can one call Zerodha support from an unregistered number?
Yes. When prompted on the support call, clients can enter the registered phone number followed by the support code for authentication.
For example, if the registered phone number is 9XXXXXXXXX and the support code is 0007, clients should enter 9XXXXXXXXX0007 when promoted. To find out support code, follow the steps in What is a support code, and why is it required to reach Zerodha’s support desk?
