What's the meaning behind the KL5 phone number?

KLondike 5 http://en.wikipedia.org/wiki/555_(telephone_number) KL5 is fictious and only for TV (555—####).
(For some reason the link won’t work for wiki…if you look up 555 or KLondike 5 you can read the article)

Phone numbers use to include a location.

Example: A local number here might have been “GLenview 3 – ####

It was a way to remember the number and told what locale you lived in.

In my area we had 29 for Ax of Axminster. Today we would say 297-xxxx and in my grandparent’s day, they would say the number was Axminster 7-xxxx. We also had Amherst (26), The words were called “Telephone Exchanges” and there is an interesting list of telephone exchange names here

(Do you mean “spout” rather than “sprout”?)

@gailcalled oops, thanks for the correction.

Klonkike 5 or KLamath5, was used in older television shows; In the fifties and sixties.
Because the telephone exchanges used letters and numbers.

555—#### is a universal number for Information (what is now called Directory Assistance). So 555 is the only prefix for entertainment.

KL5 is the same prefix numbers in all movie and TV shows (555) which is an unused sequence.. They’re using KL as a throw off.
