There is a secondary reason for spacing and that is that short term memory can only cope with about 7 things at once, so it is a good idea to break numbers down into groups of less than 7 digits. Outside of London, that tends to happen with the technical breaks in the number. You have to take account of the historical exchange codes (which are still geographically significant, in most cases, to avoid an 8 digit group, in London. (It's why credit card PANs are in 4 digit groups and why it is so annoying when websites aren't prepared to strip out the spaces.) The other thing about grouping, is that when I went through the numbers already in +44 format, less than 5% didn't apply any grouping, and more than 85% used the +44 20 xxxx xxxx grouping. That's maybe as much as 90% as most of the +44 (0) people would have put splits in those places. Incidentally, I did capture a rather unusual number for a local bowls club, which was an outer London number in 7xxx xxxx format, on a notice board. Whilst most London people don't realise that they can abbreviated numbers, I believe it is still common to miss the area code, once you get outside a director area (although that might just be a generational thing, with older users less likely to be using mobile phones). _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
