Singapore's six-digit postal code maps to a single building, so with the unit number it pins down an exact address. There is no state or region line, which surprises forms built for larger countries. Here is the format, a real example, and the errors to catch.
A Singapore label is recipient, the block and street, the unit number, then the city with the postal code, then the country.
