Hong Kong PAR Submitted Twice: Use the Latest Notification Slip (2026)

Use the most recent PAR notification slip. Hong Kong's Pre-arrival Registration system replaces the prior notification when a successful new submission goes through, so the latest record is what immigration officers cross-check on arrival. The Immigration Department's eServices2 documentation states that a new PAR is normally accepted only after the existing one expires; if a second submission was accepted, the system treats the latest slip as the active record. Print physical copies of both notification slips. Carry them with the passport linked to the registration. Confirm that the passport number, date of birth, and expiry date on the slip you intend to use match the passport in your hand exactly. A successful PAR is valid for 6 months from the date of approval and permits multiple visa-free entries during that window. If the immigration officer raises the duplicate, hand over both slips and explain the accidental resubmission; presenting both shows good faith. Verify all details 24 hours before departure on the eServices2 portal. Discrepancies between passport and slip cause more denied entries than duplicate submissions. If you find a mismatch, submit a corrected registration immediately and use that slip. Most travelers in 2025-2026 forum reports describe being waved through when they presented the latest slip; the few who tried the older slip ran into 15-30 minute desk holds. Do not call the hotline expecting case-specific guidance — staff route policy questions to the eServices2 FAQ rather than confirm individual records.
