In my country you typically refer to someone by their first name informally, or first and last formally. Newspaper articles often abbreviate the first name, e.g. J. Doe. The only time I see titles used is when someone is a medical doctor, or if you are referring to your teacher (Mr / Mrs).

On the other hand a peculiarity compared to English is the surname has different suffixes for men and women, and for married and unmarried women. Divorced women will often revert back to their pre-married surname, but keep the married suffix.
