Was just on the phone with a pizza place and they kept insisting on the full postal code for delivery, not just the area name. I had to quickly check and remember that the Hawally Postal Code for my block is different from the main city centre one. Apparently the code is five digits, starting with 30 for our governorate, and the last three numbers pinpoint your exact spot or PO Box. It made the order go through smoothly, so it's worth knowing yours to avoid any dinner delays.
