I've just been looking at the TCIP (DASK) website (
http://www.dask.gov.tr/) and there is an option to obtain the property address code for your property.
There is a maroon disc in the centre of the screen which changes to various options, The one called ADRES KODUNUZU OGRENIN is one where you can get address codes. I had to open two browser pages, one in English and one in Turkish in order to navigate my way round ---- and the English one did not always work very well.
I selected Mugla, Fethiye, Merkez Merkez and finally Foca in the drop down options. I then put the street number on which the main entrance of our complex is. This then gave a list of the plot numbers, from there I was able to select my address (according to the blue numbers they stuck on my wall). You get back a building code and an address code, I suspect it's the latter they want in order to renew DASK.
Does anyone have their code and does it match the code on the DASK website ?
