Staffordshire Police say they have put plans in place to deal with an expected rise in demand ahead of England's World Cup semi-final against Croatia.
It follows a rise in 999 calls to the force following England's win over Sweden - with 841 calls on Saturday, and 779 to Sunday.
There were also 2,300 calls to their 101 number over the weekend.
The hot weather is also believed to have played a big factor.
The force are asking the public to think before they call.
Chief Constable Gareth Morgan said: “Our officers and staff are working extremely hard at this time of unprecedented demand. This past weekend saw a total of 3,643 calls to the control room and we are facing another period of very high demand with the England semi-final match on Wednesday evening.
"On top of this we are also set for a busy few days at the end of the week as we are providing support to the major national policing operation for President Trump’s visit to the UK.
“Our policing teams have robust plans in place to respond to incidents and maintain our local policing commitments. We are confident we have prepared for every eventuality but the maintenance of local policing has required us to cancel officers’ rest days and many will be working extended 12 hour shifts.
“I am immensely grateful for the professionalism, patience and continuing good humour of officers and staff here in Staffordshire and those deployed elsewhere. They are doing an outstanding job in challenging circumstances but we need the public to work with us during this period of continuing high demand to help keep our local communities safe.
"I would like to appeal to people to think before they call and consider whether an issue could be more quickly and easily addressed through other channels.
