Two-letter codes in wholesale checker

At broadbandchecker.btwholesale.com, doing an address search, the list of properties in a given postcode contains:

- the UPRN
- a two-letter code
- the ALID (I think)

I'm wondering what the two-letter codes mean? I've seen ND, ES, XX

ND in the parlance of my work usually means ‘no duct’

By this might be a red herring

The BT regional prefix I would guess
E.G. ES= East Scotland ND= North Downs

Yeah, Mine shows NI for (Northern Ireland)

Yep
EA = East Anglia
CL = Central London
…

CL= City of London

🙏 Interesting. Outside of the City but EO hanging off Canonbury exchange (N1). Vestigial / historic designation?

That makes sense and matches the addresses in question.

I know someone who is trying to get service at an "XX" address. I guess that means it's not a Gold address.

They go back decades , possibly before BT plc.
FYI, there are 6 that cover London , 3 for inner , City of London(CL), West End (WE)and Westminster (WR), and 3 for outer , London North(LN) London West (LW)and London South(LS)

🙏 Gracias for the clarification and history.

They are\were the old 'districts' as they were called then and a CSS for each of them.

The LN coded exchanges extend quite far to the North of London, Hatfield is included

Think it was part of the London charging area, extends to St Albans and Welwyn Garden City.

I never did get a map of all the BT districts across the UK, would have been interesting to see how it was divided up.

There were 29 in total, they are the first two digits of the 5 digit exchange code.

Maps were obtainable from the Drawing office and we used to have them in the office they included all the exchange names and areas on the detailed ones for each region.

My memory says there was something odd about TH, Thamesway, it could have either East Anglia or South East

Scotland: NS, WS, ES.
Wales: WN, SW.
S.West. SS, WW,
N East: NE, MY, SL
N West: LC, LV, MR.
Midlands: CM, EM, WM
East Anglia; EA, SM, TH
S East; ND, SD, ST,
London; CL, LN, LS, LW, WE, WR
N, Ireland; NI

TH is in the South East, as my exchange and the ones around me are all TH….

E.g
https://availability.samknows.com/broadband/exchange...

It was actually Thameswey covered Guildford, Aldershot, Farnborough, Camberley

MHC

Covered right across to beyond Reading/Newbury towards Swindon.

Didn't realise there were 29 so thank you for listing them all, only ever managed to have involvement with 5 of them over my time in the job.

Thameswey ….. I’d always thought the weird spelling was based on two lei era in it
Thames and Wey

Around the top end of the M4 and M3, kinda.

As in Weybridge, presumably: area bounded by the rivers Thames and Wey?

Nah, Weybridge isn’t in Thameswey patch.

Did you move ? I seem to recall you used to be off of Farnborough
