There are many banks that are authorized to offer Sukanya Samriddhi Yojana. Also, one can open an SSY account at a post office. However, one has to physically visit an authorized bank or post office to open an SSY account. There is no online facility for SSY account opening by any bank or post office as of now. But once the account is opened after the submission of all documents, one can set a standing instruction online. It is important to note that, if a deposit is not made every year, the account will fall under “Account under the default”. Hence, one can visit the nearest authorized bank or post office for opening a Sukanya Samridhi Yojana account based on their convenience.
