It used to be that almost the entire 800-555-XXXX exchange was a wasteland because only AT&T used it and only for its own services.

Apart from a handful of other 800-555 numbers, the one that was (and still is) most famous is 800-555-1212 (toll-free information).  Things have changed.

Now 555 is a commonly used exchange but it will always be a special one in the eyes of of hackers.

Below are the results of a thorough scan of the 800-555 exchange.  The numbers listed all do something interesting, whether it's a computer, a dial tone, or just an interesting voice system.
