In Leeds we still get places claiming the STD is 01132. It wasn't when it changed from 0532 (in 1994, for crying out loud) and it still isn't now. This isn't just nitpicking. My old phone number used to begin 0113 230 44xx which was fine until a new mental hospital opened up and one of the ward numbers began 0113 304 4xxx. It got to the point where I set up a voicemail message with the right number and letting the call fall through if I didn't recognise who was calling. After ticking off people for a while I found BT's nuisance calls bureau were very helpful and they gave me a new umber very quickly. It also stopped the calls I was getting in Arabic for the person who had the flat before me. Double result.

Same thing happened to me in Leicester, oddly enough
The number written on our (BT) house phone was spaced 01162 XXXXXX when it should have been 0116 2XX XXXX - apparently due to the fact that the old number had been XXXXXX and the 2 was added when the area code changed. Lots of people thought the area code was now 01162.
