If the recipient has no definite address for delivery, the sender may deposit the mail at the poste restante area in the post office, and the recipient can claim it with a proper ID.

To send a poste restante, the sender should write down the name and phone number of the recipient, as well as name of destination post office and “poste restante.” No fee is charged 15 days from the arrival of poste restante, after which there will be late claim fee calculated with number of late days. If the recipient refuses or ignores to pay such a fee, the mail will be treated as undeliverable mail. The 15-day domestic poste restante deadline can be extended to one month on written request by the recipient. International poste restante deadline is 2 months, after which the mail will be treated as undeliverable. Express poste restante deadline is 5 days and can be extended to one month on written request by recipient.

Domestic registered mail, after two failed deliveries, will be put on mail claim. The post office will send claim notice to recipient asking him to claim the mail over-the-counter. Recipient should bring the notice, national ID and a personal stamp to claim the mail within 15 days from the day the notice is issued.

1. If the recipient claims by himelf, he should bring the claim notice, national ID and personal stamp, which may be replaced by a signature.
2. If the recipient entrusts another person to claim, it requires the notice, recipient's power of attorney or personal stamp, trustee's national ID, signature or personal stamp.
3. If the recipient entrusts another person to claim value declared or insured mail, it requires the notice, recipient's power of attorney, trustee's national ID, signature or personal stamp.
4. International registered mail requiring recipient's personal claim doesn't allow a trustee to claim it.
5. If the recipient is unable to claim at the post office, he may request in writing or by phone (no phone for credit card mail for safety reason) for such mail to be forwarded to his place of work. However, this colution won't be allowed if the sender notifies on mail cover saying “no forwarding.”
6. For safety reason, the post office will copy the claimer's ID number in writing. If the claimer is concered about leaking personal info, he can request the last four digits of ID be copied as「****」or request the manager to personally check his ID and exempt his ID from being recorded.
