Portuguese addresses use a seven-digit postal code in the form NNNN-NNN, which narrows delivery far more than a four-digit code would. Truncating it to four digits is the usual cause of misrouting. Here is the format, a real example, and the errors to catch.
A Portuguese label is recipient, the street with its number and floor, then the seven-digit postal code and locality, then the country.

The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Portugal uses NNNN-NNN (for example 1250-096). The last three digits pinpoint the street or block, so dropping them to a four-digit code loses precision.
Apartments note the floor and side, for example 3º Esq. (third floor, left) or 2º Dto. (right). Keep them with the street line.
The código postal is followed by the postal locality (Lisboa, Porto), which may differ from the smaller town, so use the one paired with the code.
Names and streets use á, ã, ç, õ. Keep them or transliterate consistently, since a mix can cause mismatches in carrier systems.
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.
