All you need to know about PPF eligibility criteria
Eligibility for PPF Account includes that you must be a resident individual or acting as a guardian for a minor. Joint accounts are not allowed. Non-resident Indians (NRIs) cannot open PPF accounts, but if a resident becomes an NRI during the scheme's 15-year tenure, they can keep contributing until maturity, without repatriation. Each person can only have one PPF account and must declare it when opening the account.
Residents and individuals serving as guardians for minors have the eligibility to open a PPF account.
