To solve difficulties in confirming whether or not a proxy receiver surely hands over a parcel to an addressee in the case of 'proxy receiving'.

When the parcel is left to the proxy receiver, a deverer brings back the stub of a delivery voucher to a collection and delivery center. The home delivery service office renews the state of the applicable parcel to 'Received by a proxy' on a Web site based on the brought-back stub. The addressee takes out a premium tag from the parcel and informs described information to the home delivery service office. The home delivery service office confirms that the parcel falling under the informed parcel ID is 'Received by a proxy' and the stub brought back by the deliverer is accorded with the parcel ID informed by the addressee. Later on, the home delivery service office provides the premium according to points to the addressee.
