Former Zimbabwean Test umpire Russel Tiffin has been named as one of the umpires for the three one-dayers while the rest of the panel announced by the PCB is made up of Pakistani umpires.
An official in the Board said while the ICC's refusal to send match officials was disappointing but was expected.
"They had made their views clear about having security concerns when at the last ICC meeting the issue of inviting Zimbabwe for a series was brought up," the official said.
The umpires include Ahsan Raza and Shozab Raza for first T20 and Ahsan Raza and Ahmed Shahab for the second T20. Aleem Dar, Sohzaib Raza and Ahsan Raza will partner Tiffin in the ODI games.
