"112" is an emergency number for contacting the fire brigade, ambulance and police in all 27 countries of the European Union.

Calls to this number for contacting the police are forwarded to "101", losing response time.

All Belgian telephone numbers dialed within Belgium must use the leading '0' trunk code.

Numbers are usually provided by Orange (formerly Mobistar), Base, or Proximus, and more recently by Telenet as well.

Note that subscribers may have been ported to another network, due to mobile phone number portability.
