postcode

[Pimpernel]

Hello,

I am moving into a new flat. The building houses a bank on the ground floor, and the next four floors were previously offices, and have been reconverted into bedsits and 1-bedroom flats.
My problem is the following: the real estate agency had initially told me the postcode was *** *DZ, and later told me that it was *** *DX. The electricity supplier and the water supplier tell me it is *** *JR (the same postcode as the bank). BT didn't manage to find the building at all.
I've had a look at the other tenants' mail (we don't have letter boxes yet) and some of them use DX, others JR. The site developer told me he didn't know which was the correct postcode.
I've checked the 'postcode finder' page on the Royal Mail website and it should be *** *JR. However, none of the flats are listed yet, only the bank.

How do I establish which is the correct postcode? Any chance of *** *DX not having been 'registered' yet? Would the Land Registry have this information?

Thanks in advance.

it sometimes takes a while
for the moment the out code should be good enough ie ab13 the in code ... daft as it sounds ... have you been to the library? or even your local post office
and the council should have it too - they granted planning

your problem is - it's possible that a single floor could have more than one in code ... so it's not something you can guess
our road has odd and evens ... it's a bit of a lottert

No one uses 'em anyway :)

Keep the DX - its often used by solicitors as well as banks for internal courier messaging. You could get delivery of bank cash;)

Thanks for your answers.
'DX' are the 2 last letters of one of the 6-digit postcode the agents gave me (such as AB1 2DX); it's not a DX address!
Anyway, I'll see how it goes. I've got to call back BT today, I hope they manage to book me an appointment, postcode or not postcode. Have to check with the site manager where the BT box is, and whether it is accessible at all times, or whether I need to have him around when the BT engineer calls.
Back very painful from carrying all those cases and bags and boxes yesterday!
Thanks again.
