Romanian addresses place a six-digit cod poștal before the locality name, and most towns carry a județ (county) line, except Bucharest, which is split into six numbered sectors. Apartment addresses stack extra parts (bloc, scara, etaj, apartament) that Western forms have no field for. Here is the correct structure, a real example, the postal code rules, and the mistakes that cause returns.
A Romanian address runs recipient, street with any apartment details, the six-digit cod poștal and locality on one line, then the județ (county), then the country. Bucharest replaces the county with a sector number.

It resolves to a locality and, in cities, to a street or building, so an accurate code is often what makes delivery reliable in dense areas.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Romania switched to a six-digit code in 2003, so a five-digit code fails sorting. It is written before the locality name, as in 400015 Cluj-Napoca, not after it.
The capital is divided into six numbered sectors (Sector 1 to 6). A Bucharest address needs the sector rather than a județ, and the sector is reflected in the postal code.
Outside Bucharest, addresses carry the județ (for example Jud. Cluj) because locality names repeat across counties. Poșta Română routes on the code, but the county disambiguates the destination.
Apartment addresses add block (bloc), stairwell (scara), floor (etaj) and apartment (ap.) after the street. Dropping the bloc or scara sends the courier to the wrong entrance.
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.
