They are still very common amongst some Jewish groups, most notably the Yemenite Jews who call them simanim and the Chasidic Jews. Various groups adopt various styles, such as those of the Chabad-Lubavitch organisation who have peyot which begin at the temple of the head and hang down as far as the bottom of the ear, or the Belz who wrap them around their ears.
They are a voluntarily stringent observance of Leviticus 19:27.
