Abstract: To reduce a trouble for a user to receive packages when delivery companies that collect the packages from respective shipping sources are different. A collective delivery system (10) is a system for delivering a plurality of packages collected by a plurality of different delivery companies from one or more shipping sources to a single predetermined delivery destination. A first delivery control unit (10C) is able to set first delivery information to be associated with each of the packages such that the package is delivered from the shipping source thereof to a predetermined place different from the single delivery destination. A second delivery control unit (10D) is able to set second delivery information to be associated with each of the packages such that a single delivery company collectively delivers from the predetermined place to the single delivery destination.
