I supervise the delivery of Yellow Pages throughout several areas of East Anglia. We have some people who complain bitterly if they believe that they've not received their book (notably, of course, those who pay to advertise in it!). Their names and addresses are added to a VIP list for futures deliveries. However the VIP lists also include people who've specifically indicated that they don't want to receive Yellow Pages any more. To get your address added to the 'non-delivery' list, simply call 0800 555 444, free of charge.

PS: The printed Yellow Pages remain vastly superior to Yell.com, simply because many more businesses pay for display ads in the print version than on the website. So for example, you might be looking for a garage that specialises in Citroen cars. Yell.com will list all of the garages in your area but, without the display advertising that appears in the printed version, you won't be able to see which ones are of interest to you.
