"Miss Utility", "Dig Safe", "Click before you dig", or Underground Service Alert are services that allow construction workers or homeowners to contact utility companies, who will then denote where underground utilities are located via color-coded markings typically up to and not past the user's service connection or meter. Utility lines on the other side of the meter or service connection are considered to be part of the customer's property, and will typically not be located by these services. Failure to call such a number ahead of time may result in a fine or even a criminal charge against a person or company, particularly if such negligence causes a major utility outage or serious accident, or an evacuation due to a gas leak. Hitting a water main may also trigger local flooding or require a boil-water advisory. The following is a partial list of countries with one-call services for utility location: Australia: The national "dial before you dig" number is 1100. Canada: In Canada, there is no unified number for the country. However, it has the "Click Before You Dig" website that provides access to the hotline for each of the provinces. New Zealand: Each utility is responsible for marking its own services. A private company (https://www.beforeudig.co.nz/) has been contracted by many utilities and city councils to provide one-call services and corridor access requests. A person planning to dig in the public roadway can lodge a ticket with BeforeUDig and have the utilities in the area notified who in turn will respond with maps of their assets. United Kingdom: In Scotland there is an online web based service called Vault (short for Scottish Community Apparatus Data Vault), which allows registered users to specify a polygon on a map and immediately obtain an interactive map of all major undertakers owning underground assets, except the principal telecoms operators). In the rest of the UK, there is no dial-before-you-dig service. Instead the onus is on excavators to ensure that they do not damage buried services. This has resulted in a class of locating tools which are simpler to use, and are called Cable Avoidance Tools (CATs), and the associated signal detectors are called Gennys. United States: As required by law and assigned by the US Federal Communications Commission (FCC), the 8-1-1 telephone number is used for this purpose across the United States.
