Zone Zero

A typical rotary telephone dial used in Kakoma-participating nations. The numbers run from 0 (furthest from the finger stop) to 9 (closest), with an extra digit ~ used to dial the operator, and separate codes within the telephone number.

The Kakoma Telephone Directory Numbering Scheme (KTDNS) commonly known as Zone Zero, is a telephone numbering plan devised in the Kúúlist Bloc in the late 1950s. Originally linking the military telephone infrastructure of Helsonia with Helsonian-occupied areas following the Great Ekuosian and Pangyeoun Wars , the scheme was rolled out for civil use in various countries between 1957-1962.

The Kakoma system is primarily used in Northwest Ekuosia, Akulanen, and Soltenna. Until at least 2001, the telephone scheme was used signficantly for state surveillance, monitoring and espionage operations.

The standard format of telephone numbers using the scheme is as follows:

(~~ COUNTRY CODE) ~ REGION CODE ~ SERVICE CODE ~ UNIQUE NUMBER ~
