What is a postal code and how do you find one?
What is a postal code?
A postal code is a five-digit number that shows which delivery area an address belongs to. PTT sorts mail and parcels by this code, so a correct code keeps a shipment from going to the wrong branch and arriving late.
In Turkey the first two digits are the province’s licence-plate number: codes starting with 34 belong to Istanbul, 06 to Ankara and 35 to İzmir. The next three digits identify the district and its delivery area.
When do you need one?
Postal codes are asked for in courier and e-commerce orders, billing and delivery address forms, bank and insurance applications, official petitions and parcels sent abroad. A wrong or empty code blocks the form on many sites.
How to find the right code
Type your neighbourhood name in the search box. Neighbourhoods with the same name exist in different districts, so adding the district or province (for example “Cumhuriyet Kadıköy”) narrows the result. You can also pick a province and district from the lists to browse every neighbourhood there.
Codes are issued per neighbourhood. In large or new neighbourhoods a different code can apply by street, so for official procedures confirm the result with PTT’s address-based lookup.
FAQ
Questions about postal codes.
How many digits does a Turkish postal code have?
Five. The first two digits are the province’s licence-plate number; the last three show the district and delivery area.
How do I find my postal code?
Type your neighbourhood, district or province in the search box on this page. Results appear as you type, and clicking a code copies it.
Can neighbourhoods in the same district have different codes?
Yes. Codes are issued per neighbourhood, so a district can have dozens of codes while some small neighbourhoods share one.
Does a district have a single postal code?
Not usually. Small districts may have one, but large districts have several. The search results show every code for a district.
Is the data up to date?
The list is based on 2025 data. Newly created or merged neighbourhoods can differ; for official procedures confirm with PTT’s address lookup.
Can I build a postal code lookup for my own site?
Yes. We can add province, district and neighbourhood selection with automatic postal code filling to your address form. Get in touch through the contact page.
