Different batches perhaps? At a glance, 3966/67 were first registered in March 2002, and the PJ02xxx batch appear to be May 2002 onwards.
They're all registered in Preston, by the Preston DVSA office. They'll have most of the range of the Preston area, with the Carlisle office having a handful of letters for their own registrations.
