Public telephone networks in countries around the world have a single emergency
telephone number (emergency services number), that allows a caller to contact local
emergency services for assistance when required. The emergency telephone number
may differ from country to country. It is typically a three-digit number so that it can be
easily remembered and dialed quickly. Some countries have a different emergency
number for each of the different emergency services.

emergency services in an emergency situation.
