DWP white envelopes

All letters now from the DWP, have been for a good while now. Easyiest way to tell is on the back with the Belfast and the P.O. Box number on them.

The DWP started sending out computer / system generated letters in white envelopes about a year ago. Apparently it is a change that has been forced on the DWP by Royal Mail and is linked to the way RM sorts bulk post. A tweet by the DWP from last April stated:

From 5 April some DWP system-generated customer notifications will be sent in white rather than manila (brown) envelopes. This requirement is driven by a change in the way Royal Mail sorts bulk post. The new system requires a legible barcode to be printed onto the envelope. Testing has shown printing onto our manila envelopes regularly fails.

Some of mine have been white, but I've still had the odd brown emvelope this year.
