Address numbers are unique numerical identifiers assigned to buildings or properties along a street. They help in locating specific addresses for mail delivery, emergency services, and navigation. Typically, these numbers are displayed prominently on the front of a building or near the entrance. The numbering system usually follows a pattern, with odd numbers on one side of the street and even numbers on the opposite side. This organization helps people find addresses more easily. In some areas, the numbers may also indicate the distance from a designated starting point, such as a city center or intersection, enhancing clarity in navigation.
