Kuwait addresses are built from area, block, street, and building numbers, and much of the country's mail still runs through PO boxes. There is a five-digit postal code, but it is frequently left off. Here is the correct structure, a real example, the code rules, and the mistakes that cause failed deliveries.
A Kuwait label is recipient, optional company, the block, street, and building numbers on the address line, then the postal code and the area (city). Mail addresses often use a PO box in place of the block and street line.

The code helps sorting, but a complete physical address (or a PO box) is what actually gets a parcel delivered.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Kuwait has no door-to-door postal delivery for many addresses, so PO boxes are the standard mail destination (P.O. Box 888, 13009 Safat). Ecommerce couriers deliver to the physical block and street, so collect both the PO box and the physical address where you can.
A Kuwait address is ordered area, then block, then street, then building: Block 3, Street 7, Building 12. The block groups the streets within a district, so dropping it leaves the street number ambiguous.
Kuwait's five-digit code is real but inconsistently used, and many valid addresses ship without it. A form that hard-blocks on a missing or short code rejects legitimate Kuwaiti addresses, so treat the code as optional and validate the area and block instead.
The area or district (Salmiya, Fintas, Hawalli) functions as the city line and drives local routing. The six governorates are administrative and usually not needed on the label.
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.

The national operator. Much of its delivery runs through PO boxes rather than to the door, and the five-digit code is often omitted, so the area and block guide sorting.
The dominant regional courier for ecommerce last-mile in Kuwait. It delivers to the physical area, block, street, and building, so a complete physical address enables first-time delivery.
International express carriers for inbound shipments. Include the country line and the full block and street; they surcharge address corrections when a parcel needs a manual fix.
