After installation, an agent visits the building for a day or two and notifies every delivery person of the existence of the locker and how it functions. We can also add visual signage to help delivery people. However, it’s impossible to ensure the use of the lockers. Every delivery person can choose to use it or not, at their convenience. In contrast, when lockers are well located (next to the entrance), the rate of use is extremely high. A good practice is to ask delivery people to use the lockers when you open the front door of your building through the intercom.
