It is at the "proposed change" status at present in most places in the US, but many phone service companies are planning very soon to cease publishing the White Pages (Residential Listings). They will NOT BE automatically distributed to all subscribers.
There are vague promises that anyone who wants one will be able to purchase a copy, but the appearance is that they'd like people not to order one and likely will eventually cease even making the lists for any sort of publication.
In the US, cell phone numbers have never been listed in any easily available directory, and the number of different service providers probably precludes anyone being able to list any significant portion of them. Recent surveys have shown that about 30 percent of "households" have cell phones but NO LANDLINE and hence no number that at present can be listed in a directory. Something between 60 - 80 percent of individuals report that they now use cell phones exclusively. (The numbers don't add up, but remember that nobody has a list to check them against.)
