With the invention of the telephone communication barriers vanished. With more and more ideas developing on this novel device, it is now possible to find out a person’s telephone number if you know the name and the address.
This facility is the telephone number look up service. Even if you do not have the correct address but you know the city and zip code that would be sufficient. From a number of records generated with the same name, you can easily locate the person you were looking for. This new single search window is extremely convenient and easy. It does away with the need for bulky telephone directories. Moreover, it would not be physically possible for a person living in Florida to have a telephone directory of the state of Michigan or for that matter Alaska.
There is no need though to keep a library of telephone directories with you. The most important drawback of any telephone directory is that it has an annual update, and by the time you receive your copy, several more telephone numbers are either added, or deleted from the database.
So what useful purpose does an old-fashioned telephone directory serve? Except for being a historic document, the telephone directory has long had a natural death. With internet being a household utility and with telephone number look up being freely available, being connected with someone is as easy as 123.
The telephone number look up feature has become possible because of the area code break up introduced in 1947 by AT&T and Bell Laboratories. With years of development and refinements that followed, it is now physically possible to locate a person’s phone number even if he is residing in another state. In fact, it is even possible to find out the telephone number of a person located outside the US with a global search.
