What is the "evening prompt mail delivery" service?
A:
If an addressee is unable to receive registered mail at home during regular post-office-operating hours due to work or some other factor, the person can request the post office arrange by telephone or by correspondence to deliver the mail in the evening by prompt delivery service. An additional prompt delivery charge will be collected at the time of delivery for ordinary registered mail requested for evening delivery. If a sender requires the service, "prompt delivery in the evening" labels are available at post offices.
