Turkish addresses nest a neighborhood (mahalle) and district (ilçe) inside a province (il), with a five-digit postal code whose first two digits are the province plate code. Dropping the mahalle or district is the usual cause of misrouting. Here is the format, a real example, and the errors to catch.
A Turkish label is recipient, the street with its number, the neighborhood and district, then the postcode and province, then the country.
Mehmet Yılmaz personal or business recipientİstiklal Caddesi No 12 street (<code>Caddesi</code>, <code>Sokak</code>) and building numberBeyoğlu the mahalle (neighborhood) and ilçe (district)34433 İstanbul the 5-digit code, then the province (il)TURKEY required for inbound international shipmentsThe posta kodu is a five-digit code whose first two digits match the province's plate number. The district (ilçe) and neighborhood (mahalle) do much of the local routing for PTT.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
A Turkish postcode's first two digits match the province's vehicle plate code (34 Istanbul, 06 Ankara, 35 Izmir). If they do not match the named province, the address is inconsistent.
Addresses nest a mahalle (neighborhood) inside an ilçe (district). Both are needed to route within a large province, so neither should be dropped.
Streets carry Turkish types: Caddesi (avenue), Sokak (street), Bulvarı (boulevard). Keep them as part of the address.
Names and streets use ç, ğ, ı, ö, ş, ü. 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.

The national postal operator. Routing uses the five-digit postcode, with the district and neighborhood refining delivery, so all should be consistent.
The dominant domestic parcel carriers for Turkish ecommerce. They rely on the mahalle, ilçe, and province for accurate last-mile delivery.
