Like the rest of Transcarpathia, Chop was part of Hungary until 1920, when, as a result of the post-World War I Treaty of Trianon, it was included in the newly created Czechoslovakia, where it belonged to Slovakia, not to Subcarpathian Rus. During World War II, under the First Vienna Award, it briefly became Hungarian again. But, after the war, as part of the Czechoslovakia–Soviet Union relations, it became part of the expanded Ukrainian Soviet Socialist Republic (now Ukraine).

According to the Ukrainian national census, Chop had a population in 2001 of 8,919, of whom 40% were Ukrainians, 39.2% ethnic Hungarians and 20.8% Roma, Russians, Slovaks, Belarusians, and Jews.

Chop is an important railway junction in Ukraine where the Lviv-Stryi-Budapest railway line meets the Lviv-Uzhhorod-Košice line. There is also a line running eastwards to Romania via Korolevo and Halmeu although there are currently no regular passenger services.
