3-digit numbers

In the national numbering, the number series 100-189 is reserved for use for standardised special numbers, which are usually three digits long.

Under Section 20 of the Numbering Regulation, such numbers primarily serve two purposes:

  1. nationwide services of great importance to society, and
  2. services that are closely linked to the public telephone service and which help to improve and develop this for the benefit of end users.

Examples are the emergency numbers 110 (fire), 112 (police), 113 (ambulance).
