Hi all, I asked about finding what the 'real' number for a company
0870 number was some time ago. However, it was pointed out that
sometimes there is NO geographical equivalent.
So I didn't pursue this any further.

A few days ago someone phoned me. It was a wrong number but they'd
dialled a geographic number rather than an 0870 one.

I tried dialing the number they gave and it connected to a Bank. I
assumed they'd had finger trouble as the last 4 digits of the number
they gave me almost matched my number. So I tried dialling a few
numbers 'near' the one they'd tried and didn't manage to dial myself.
(By 'near' I mean if you meant to type 1 you might have hit 2,4 or 5
and so on..)

Is it possiible that the number was mangled by the network instead of
by finger trouble? In which case, instead of being a 'nearby' number
it could anything.

If I was to try a bit of 'war dialling' are there any numbers I can
ignore. I know about 999, 112, 123 but wondered if there are ranges of
numbers, after the area code, I can ignore.

Many thanks

Yes, Ofcom publish the ranges which are allocated. See
http://www.ofcom.org.uk/telecoms/ioi/numbers/numbers_administered

E.g. For my own area, 01926 if the whole range 01926 000000 to 01926
999999 were allocated that would be a million numbers. The Ofcom data
shows the 54 complete ranges of 10,000 numbers and 34 ranges of 1,000
numbers which have actually been allocated in 01926. I.e. there are only
574,000 potentially valid numbers in 01926, the unallocated 426,000 can
all be ignored.

Note that although local numbers starting 0 or 1 won't be dialable
without the code, some ranges are allocated. They can only be used
in full national form. E.g. in 01926 the range 10xxxx is allocated.

Thanks for that. It's just the sort of info. I was after.
I've got 1000 numbers to try and should be able to ignore a fair few
of them now. (or at least try them last)

NOT all 0870 numbers terminate at geographic PSTN's. Some terminate directly 
at something like a SIP address, E164 H.323 extension or internal routing 
code.

Ofcom's telephone numbers for drama purposes lists ranges that will
not be allocated in the foreseeable future.
