Following Liverpool's qualification for the semi-finals of the Champions League, the match at St. James' Park will be played on Saturday, 4th May with a 7.45pm (BST) kick-off.
With the Reds challenging for a first league title in 29 years, the game against Rafa Benítez's old club has become one of the most eagerly-anticipated fixtures of not only Newcastle's season but the entire 2018/19 Premier League campaign.
Tickets for the game went on sale at 10am on Thursday, 25th April, and sold out within hours.
Liverpool began selling their allocation of 3,231 tickets earlier this month and away supporters not in possession of a ticket are urged not to travel.
The club are aware that there is a demand for tickets from Liverpool supporters way in excess of their allocation and would urge Newcastle United fans not to try and sell their tickets to visiting fans, as this would be a breach of the terms and conditions of their ticket.
Newcastle United would also appeal to Liverpool fans not to try and obtain tickets in the home areas of St. James' Park, as it is a breach of the stadium ground regulations for away fans to be in home fan areas. Any Liverpool fan found in home areas will be ejected from the stadium.
