Yes, it is completely normal for an MPF platform to lock early retirement and normal retirement withdrawal functions when a member is under 60. Under Hong Kong MPF regulations, early retirement is available only from age 60 onwards, provided the member has permanently ceased all employment and self-employment and makes a statutory declaration of no intent to work again [1][2]. Normal retirement withdrawal is generally available at age 65 [2][3]. The locking mechanism is a standard automated eligibility check based on your recorded birth date, designed to prevent ineligible applications and ensure compliance with statutory requirements [1][2].

If the functions have been locked before and remain locked, this reflects the system working as designed. However, if you believe your birth date is recorded incorrectly or your employment status has changed, contact the eMPF customer service hotline at 1832 2622 or your scheme trustee to verify and update your records [1]. Even under 60, you may still access other withdrawal grounds such as permanent departure from Hong Kong, total incapacity, terminal illness, or a small balance claim [2][3].
