In this chapter we make use of The Netherlands' number plan as an example to explain an alternative format to the USA and Canada one.
This example is fairly standard across the world, in as much that Fixed Line telephone numbers contain a prefixed geographical area code to the number, whilst Mobile telephone numbers are prefixed with a fixed number to distinguish it from other types of numbers i.e., fixed line, toll free, mobile pagers, etc.
The Netherlands' geographical numbering plan implements a system of area codes. An area code consists of two or three digits. The larger cities and areas have two digits with a subscriber number of seven digits, permitting more local numbers. Smaller areas use three digits with a six-digit subscriber number.
Fixed line area code examples:
10 Rotterdam
111 Zierikzee
113 Goes
114 Hulst
115 Terneuzen
117 Sluis
118 Middelburg
13 Tilburg
15 Delft
On the other hand, non-geographical number prefixes are ones like:
06 mobile telephone operators,
0800 free service numbers,
084, 085 used for VoIP
087 voicemail and virtual private numbers
