Turkey Postal Code Lookup

How it is calculated

This is a lookup, not a calculation. It searches a bundled copy of the Turkish postal service (PTT) code list for Turkey and Northern Cyprus. There are three ways in. If the search box contains only digits (2 to 5 of them), the tool reads it as the start of a postal code: the first two digits are matched to a province (the same number as the province's licence plate code), then every neighbourhood (mahalle) whose code begins with your digits is listed. If it contains text of at least 2 characters, it matches province, district or neighbourhood names, ignoring Turkish accents and capital letters, so "kadikoy" finds Kadıköy. You can also pick a province and then a district to list all its neighbourhoods. At most 600 rows are shown; a count with a + sign means the list was cut off, so narrow your search.

Common mistakes

• Typing a street name or building number. The list only goes down to neighbourhood level, so one code can cover many streets, and a street cannot be searched.
• Entering a code with a space or letters, such as "34 710". Spaces or letters turn it into a text search instead of a code lookup; type the digits together.
• Searching with a very common neighbourhood name and not choosing the district. Many places share names across provinces, so check the province and district label in each row.
• Treating a partial code result as final. If you type only 3 digits, you will see many different areas; the full five digits are needed to identify one.
