The Prince of Wales website lists the following Royal Households, I have cross-referenced this list of the public register of Data Controllers held by the ICO:

(believe it or not there is an order of precedence for the Households, they are listed here in that order)

For many people it is cheaper to call a geographic phone number (it depends on your tarriff).

So Government Departments can help citizens and small businesses save money in a recession just be publishing lists of numbers.

“The geographical number for the Self Assessment/PAYE DMB 0845 366 7816 telephone
number is 01506 476 066.”

“The geographical number for the Self Assessment card payments 0845 305 1000 telephone
number is 01726 209 025″

The Department for Work and Pensions have no geographic numbers an that means benefit claimants an potential claimants will have to pay more to call them on 0845 numbers. This is especially unfair as a proportion of the calls are likely to relate to errors made by the Department.

I do welcome the fact that the number for crisis is an 0800 number but many people in real financial difficulties may be trying to call using mobiles and on some networks 0800 calls are very expensive. I would urge the DWP to ensure they can provide a geographic alternative to all non-geographic numbers to make life just a little easier for people who have lost their jobs during the recession.
