The invention relates to the technical field of logistics, and discloses a building based parcel delivery system. The building based parcel delivery system comprises a receiving module, a verification module and a terminal, and is characterized in that the receiving module sends an incoming reminder to the terminal through a first information sending module, the terminal receives the incoming reminder and sends pickup confirmation through a second information sending module, a first information receiving module of the receiving module receives the pickup confirmation, generates a pickup code through a pickup code generating module, sends the generated pickup code to the terminal and the verification module through the first information sensing module and controls a delivery unit to transport the parcel to the floor where the recipient is located at the same time, and the verification module opens an isolation element after the terminal passes verification of a matching unit of the verification module at the floor; and the isolation element is closed automatically after the parcel is picked up, that is, after the verification module judges that the parcel is taken out through an induction unit. The building based parcel delivery system is simple and reasonable in structure, and the pickup code is sent after parcel pickup is confirmed through the terminal, thereby being capable of effectively avoiding a circumstance that the recipient deletes the pickup code mistakenly, and saving the time of the recipient for picking up a parcel downstairs.
