Seam Zone is a term used to refer to a land area in the Israeli-occupied West Bank located east of the Green Line and west of Israel's separation barrier, populated largely by Israelis in settlements such as Alfei Menashe, Ariel, Beit Arye, Modi'in Illit, Giv'at Ze'ev, Ma'ale Adumim, Beitar Illit and Efrat.

The Green Line or 1949 Armistice border is the demarcation line set out in the 1949 Armistice Agreements between the armies of Israel and those of its neighbors after the 1948 Arab–Israeli War. It served as the de facto borders of the State of Israel from 1949 until the Six-Day War in 1967, and continues to represent Israel’s internationally recognized borders with the two Palestinian territories: the West Bank and the Gaza Strip.
