International Directory of Fictitious Telephone Numbers, Martin John Callanan (2011)

International Directory of Fictitious Telephone Numbers is a collection of telephone numbers that are designated never to function. Their purpose is to be reserved indefinitely for use within drama or film productions so that unsuspecting people aren’t disturbed by inquisitive viewers.

Nation states organise telephone systems with ‘numbering plans’, identifying geographical areas or service operators with number prefixes and corresponding number ranges. Some plans hold — forever-reserved — ranges of numbers varying from one hundred (some states of the USA) though to one hundred thousand consecutively ordered (Ireland). Explicitly for use in film and television programmes, producers pick from the designated ranges. The chosen digits appear fleetingly in films, or frequently over years of a serial.

Enquires were made to the telecommunication regulators of each nation state. All possible numbers for each country with such reserved ranges are ordered and listed in the International Directory of Fictitious Telephone Numbers.

The printed directory is accompanied by an apparently normal looking telephone. This telephone has been reprogrammed and reconstructed to automatically dial the numbers from the Directory, at random. The dialling tone is followed by the sound of numbers being dialled, then the response: a dead tone indicating no number, or a recorded message stating that the number is not in use, from a telephone exchange in any part of the world. The telephone then hangs-up before selecting another number to dial at random.

Digits - Say Goodbye

Highlights from Cabal's Rescue



Hairpin sets her teeth hard as she flicks a switch on the side of the Heavy. Instead of a bolt a searing LASSSSSSSSER starts firing at the cage bars.
Hairpin rolls 100 (1-100)

Of all the moronic, hair-brained, stupid plans, apparently the Black Hoods did not expect lasers. The bars melt to slag.

Hairpin didn’t expect it to work. She really didn’t, and that’s plain. “Huh.” She lowers the gun to her side and looks over at Deji. “Make a note: Black Hoods don’t like lasers. C’mon, bleeders. Time t’go.”

Deji grabs Delphie’s hand in her one good hand and rubs at it. It glows just a little.
Deji: This might hurt, but hopefully it won’t. I’m getting better at it.
Deji rolls 100 (1-100)

A beautiful golden glow envelops Delphie’s hand, knitting the flesh back together like a tapestry. The carpal tunnel is gone, too!

Deji sighs in relief and goes back to grabbing her arm. “Oh thank the stars.”

Cabal tiptoes over and puts her hands on both Deji and Delphie’s heads, pushing them down as quickly as she can to grab at the arm. She keeps her elbow balanced on Deji’s head, “I CALLED DIBS HE CONTACTED ME FIRST.”

Deji just CRUMPLES UNDER THE WEIGHT OF CABAL. Her bad leg is so fucking done.

Cabal doesn’t care, she gets a robot arm.

And let us not forget XyKar’s beautiful rolls.

XyKar rolls 8 (1-100)
XyKar rolls 4 (1-100)
XyKar rolls 6 (1-100)

THANK YOU graveheist for running such an incredible event! SERIOUSLY, THIS IS ONE OF THE MOST TALENTED PLOT WRITERS I HAVE EVER BEEN GRACED TO KNOW! A +++++ would run a million dungeons and follow into the creepy recesses of a cave with.

Powers of ten

Define the following two lists. The first one contains all powers of 10 in base 2, and the other one contains all powers of 10 in base 5:

  • 1010, 1100100, 1111101000, …
  • 20, 400, 13000, 310000, …

For any integer n > 1, there is exactly one number in exactly one of these lists that has exactly n digits.
