Royal Mail tracking number starting IW

[18catsrfurryfriends]

Have justed tried to track a parcel and it says it has gone to Abbey Wood in  error and it will be re routed immediately. So not sure when that will arrive. But just wondering if anyone has seen a RM tracking number starting IW before it is a new one on me.

I searched for Royal Mail details and they don't assign any particular meaning to IW tracking numbers.

My last few parcels were IV, so I'm assuming IW is just next in line.

Well so far this 48hr tracked parcel has taken 6 days and It is still not out for delivery so I would assume it will be delivered Monday which means it has taken 8 days to get here.
