Pakistani authorities have imposed "reciprocal" restrictions on the movement of US diplomats in the country after Washington took similar measures.
A letter sent to the US Embassy in Islamabad says the restrictions will be implemented on Friday.
The move comes after the US required Pakistani diplomats to get permission five days in advance to travel more than 40km from their embassy.
The measures are likely to strain ties between the two sides.
It was unclear what prompted the moves but the developments come weeks after Pakistan barred a US diplomat from leaving the country after he killed a Pakistani motorcyclist in Islamabad.
US military attache Colonel Joseph Emanuel Hall, was not arrested because he enjoys diplomatic immunity.
Hall is accused of running a red light and killing Ateeq Baig on April 7.
