My country unfortunately doesn't fit that scenario. Here in the UAE there is no residential postal delivery, so if you want to receive letters you have them sent to a PO Box. Most people usually use their office's, but I have my own. That means you can reach me with simply:

    PO Box XXXX
    Dubai
    UAE

For sending parcels to be delivered by a courier you can include a physical address, however most streets here don't have names (and even if they do people have no idea what they are) so people go by directions. Which means something like:

    Flat XXXX
    Building Name next to / opposite / near Landmark
    Area Name

In most cases it's best to include a phone number so the courier can phone for directions if they get lost (without street names it's easy), and of course everyone requires a name even though I'm the only person living here and using this PO Box. That means my 'full address' ends up being:

    Name Surname
    Tel: 05XXXXXXXX
    Flat XXXX, Building Name
    Next To Landmark
    Area Name
    PO Box XXXX
    Dubai
    UAE

In most cases that never fully fits in the length of the fields, or they do something silly like requiring a postcode but limiting it to 5 digits (luckily my PO Box number is only 4 digits in length, but in reality they are [0-9]*). Anything I order from eBay has "NOTPROVIDED" on it as I left out an optional field they think should always be included :D

Edit: Area names have their own fun: There is a road going from one end of the country to the other which in Dubai is called Sheikh Zayed Road (it has a number and different names in other emirates :D), but that is also the name of an area along part of the road.
