A street address is a unique identifier for a building or a plot of land. It typically includes a house number, street name, and sometimes a suffix like "Apt" or "Suite".
Residential addresses are usually assigned to individual homes or apartments, while commercial addresses are assigned to businesses, offices, or shops. For example, a residential address might be "123 Main St" while a commercial address might be "456 Main St, Suite 100".
A house number is usually a single digit or a combination of digits, but it can also be a letter or a combination of letters and numbers. In some cases, house numbers may be skipped or reused due to various reasons like a new building being constructed in an existing lot.
In addition to house numbers, street names also play a crucial role in identifying addresses. Street names can be named after famous people, events, or geographical features, and they can also be numbered or lettered.
