Eligibility restrictions for opening a savings bank (SB) account are generally minimal, but individuals who fail to provide mandatory government-issued identification documents, proof of residential address, or tax verification numbers required by strict Know Your Customer (KYC) regulations cannot open an account. Additionally, minors attempting to open an account without a legal guardian or parent, individuals flagged on international anti-money laundering watchlists, or entities barred by specific institutional compliance policies are restricted from establishing standard retail savings accounts.
