Buying a ferry ticket North Cyprus-Turkey online

I'm considering taking the ferry from Girne (North Cyprus) to Tasucu (Turkey) this year, in which case I would probably buy the ticket online

When buying it, it asks for either a passport number or a Turkish ID card number, as well as the "country".

Does anyone know for sure the following:

If using a foreign ID card, should I put the document number in the "passport number" or "Turkish ID card number" field? Or can I use either without issues?
In "Country" should I select my cuntry of citizenship or of residence?

Sent an E-mail (in Turkish) to the company, but they haven't replied and it would be very expensive for me to call them (plus I'm too uncomfortable using the language orally).

Best Answer

Where are you from and what is your residence?

If you have a passport, you should use it and put its number into the field "Passport Number". If you don't have a passport but you are allowed to travel around these two countries with an ID card from your country, you can put its number into the same field (if the number will pass the validation).

As a country choose your citizenship country.
