I ask a friend in a mailing company to check teh post code and his returned with exactly the same list.

The online RM list is shorter but it looks as though te PAF version contains all of the addresses you listed.

Indeed, but they're ALL available from the Royal Mail database, so actually, I'm not convinced it's that difficult. Anyway, that's my rant for the day...

One of the good things is that if an address is incorrect, you can't actually change it - even though the option is on their web site.
I was about to have an operation a few years ago and they checked my name and address (as they do) and I said it wasn't correct, but would do.
Never mind, the nurse said, I'll go and change it. I said it was a waste of time and when she came back lo and behold, it accepted the change but when she checked, it hadn't changed.

In reply to a post by BatBoy:

Only another 34,999,999 to go...

I think its only 34,999,995 to go
'though all seems a bit fishy

I've just checked against a PAF file dated 15/03/2013 - it returned just the addresses shown by http://www.royalmail.com/postcode-finder.
