At least two schools in the county have been affected by the hoax on Wednesday, one in the Chorley area, and another in the East of the county, but specific details have not been released.
Many students across Lancashire have already started their Easter holidays.
Two schools in the Greater Manchester area have initiated "lockdown procedures" as a precaution.
According to reports, on this occasion the affected schools have been told teachers and children "will be hit by a car" outside school grounds.
The National Police Chiefs' Council said an incident had been logged on Wednesday involving numerous establishments and locations.
A spokesperson for the NPCC said: "We have heard that a few forces have received reports.
"There's a process going on now to have a look at that and see what needs to be done.
"Last time the response was led by the National Crime Agency, so that is quite possibly going to be the case again."
