Most official documents from developed countries ask for a physical address, which is often confusing unless you have lived there. A physical address refers to where you can be found, either the workplace or at home – not the post office box.
It often refers to an office or house number, and the street or avenue where a house or office is located. An example could be 1108 Fairmont Avenue, 40706. The first number is the house or office block, and the last is the postal code. Other countries like the UK have a more complex address system.
