...So I received a letter this week from the DWP, asking for my bank details & further private information.
The letter is written on official DWP letterheaded paper BUT it is not signed & no name of the sender is printed anywhere on the letter.

The letter ends by:
Yours sincerely,


Site Manager
WDP

The letter has my National Insurance Number printed correctly but also has two other reference numbers, which I do not recognise ?

Is a DWP letter which is NOT signed and NO name printed official ???
