Macao has no postal code, so the address does the routing on its own: a Portuguese or Chinese street name, a building with its floor and flat, and the district. Western checkout forms that demand a ZIP or a state break it. Here is the correct structure, a real example, and the mistakes that cause returns.
A Macao label runs recipient, optional company, the street with its number, the building with floor and flat, the district, then the country. Portuguese and Chinese versions are both valid, but they should not be mixed on one label.

Because routing depends entirely on the street name, building, floor and flat, those lines carry the weight a postal code would elsewhere and must be complete and correctly spelled.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Macao is one of the few places with no postal code system. Macao Post (CTT) routes on the street, building, floor and flat. A checkout that makes a postal field mandatory forces customers to invent a code, which helps no one.
With no postal code, the Edifício (building) name plus the floor (andar) and flat letter are the most important lines. Drop the floor or flat and a courier cannot find the unit in a high-rise.
An address can be written entirely in Portuguese or entirely in Chinese, and both are valid for Macao Post. Mixing a Portuguese street with a Chinese building name on one label can confuse sorting and last-mile delivery.
Macao splits into Macau Peninsula, Taipa and Coloane, with the Cotai strip between the islands. The district disambiguates identical building and street names across the territory, so it should always be present.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.

International carriers for inbound shipments. Include the country line as Macao SAR, China; they charge address-correction fees when a floor or flat is missing and the courier cannot complete delivery.
