You are correct Marggie, you can only get your TC Kimlik number after you have your RP as the number from your RP book has to be entered on the website to get the Kimlik number. All yabanci numbers start with 99. I have written our Kimlik numbers in the front (along the top edge) of our RP books in pencil. Didn't get any complaints about defacing the book from the passport police when we renewed residency last year.
