At Space Jainam, can IPO bids be placed only through the UPI ID linked to the primary bank account?

• For individual accounts: - using any bank's UPI ID in the applicant's name to apply for IPOs is possible.
• However, in the case of joint accounts: - the applicant must be one of the account holders in the bank account linked to space. 
• Thus, it is not permissible to use UPI IDs of those bank accounts in which the applicant is not an account holder to apply for IPOs.
