Reference excerpt

A harmonised service of social value is a type of freephone service available in the European Union and in some non-EU countries (including the countries in the European Economic Area and United Kingdom), which answers a specific social need, in particular which contributes to the well-being or safety of citizens, or particular groups of citizens, or helps citizens in difficulty. The phone numbers and the corresponding service descriptions are managed by the European Commission and harmonised across all EU and EEA member states. Harmonised services of social value use the prefix 116, which is then followed by three digits indicating the type of service. After the commission has assigned a number, it is then up to the telephone regulator in each country to allocate the number to a telephone service provider and providing organisation of their choice. The first telephone numbers to be allocated are 116 000 (missing children helplines), 116 111 (child help lines) and 116 123 (emotional support helplines).

Assignments As of August 2026, the following numbers have been assigned by the European Commission:

The number 116 112 will not be used in order to avoid confusion with the single European emergency number 112. In addition, the number 116 116 is in use in Germany as an anti-fraud hotline. A reservation by the commission obligates member states to make the numbers available for registration by interested parties. However, the listing of a specific number and the associated harmonised service of social value does not carry an obligation for member states to ensure that the service in question is provided within their territory.

National implementations Each service is now available in at least part of the EU, plus EEA and the UK. The 116 117 medical assistance line is the least-widely implemented so far, having only been activated in Austria, Germany, six Italian regions, and former EU-member Great Britain. By contrast, the 116 000 missing children line is active in 27 countries and the 116 111 child helpline is available in 22 countries.

Similar services in other countries Similar phone number services exist in other countries to serve specific community needs.

Australia

Police Assistance Line – 131 444 In Australia the phone number 131 444 is the Police Assistance line and can be used for non-emergency contact with Police to report a crime, or to make enquiries. Each State or Territory police force administers the Police Assistance line, with routing of a call taking place based on where the call connects if called on a mobile phone. Issues can arise at border towns, or particularly around the Australian Capital Territory (ACT) as it is located entirely within New South Wales (NSW), calls made on a mobile phone may be connected in NSW or vice-versa. 131 444 is called "Policelink" in Queensland.

Crime Stoppers – 1800 333 000 In Australia Crime Stoppers is a not for profit run charity organisation that works closely with local police, and allows people to report crime, provide information about unsolved crimes or report suspicious activity anonymously. Reports can be made online, or via the phone number.

Emergency Alert Australia – +61 444 444 444 Emergency Alert Australia is a system that can send text messages or voice recordings to mobile phones and landlines in a specific geographic area to warn the public in that area of an emergency situation, such as bushfires, floods, etc. The messages come from the phone number 0444 444 444 (or +61 444 444 444). The system is also used in NSW for people to look out for high risk missing persons, such as the elderly, or those with mental health problems. The phone number cannot receive calls or text messages.

New Zealand

Police non-emergency - 105 The New Zealand Police operates 105 for non-emergency calls where an immediate response is not required or when the event has already taken place and nobody is in any danger, such as a stolen car, property damage, to add additional information to an existing police report or to contact the local police station. Police launched the number on 10 May 2019 and is available for free 24/7 by phone, or online via the 105 website. The number was created to give the New Zealand public another way to contact police to ease pressure on the 111 emergency telephone number.

Police road incident - *555 The New Zealand Police operates *555 for reporting road incidents or an unsafe driver such as crashes without injuries, minor obstruction to roadways or unsafe, but non life-threatening driving. When you call the police communicator will ask you where you are, how long ago the incident happened, the vehicle licence plate and what is happening now. The information will be passed along to frontline police, but will often only result in a warning letter. Police still urge drivers to call 111 for more serious instances such as a serious motor vehicle crash or any instances where life is at risk.

Crime Stoppers - 0800 555 111 In New Zealand Crime Stoppers (Māori: Aukati Takahi Ture) is a not-for-profit run charity organisation that anonymously passes along reports to police, and allows people to report crime, provide information about unsolved crimes or report suspicious activity. The public can make reports by phone, or online via the Crime Stoppers website.

Healthline - 0800 611 116 Healthline is a free over-the-phone health service that operates 24/7. Funded by Health New Zealand | Te Whatu Ora the line is used for non-emergency health advice from nurses and paramedics. Healthline is not to be confused with the 111 emergency telephone number which handles emergency medical events.

Worked examples

Example 1 — a first encounter with Harmonised service of social value

Start with the simplest possible case. Write down what Harmonised service of social value claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Harmonised service of social value before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Harmonised service of social value ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Harmonised service of social value

In research: Harmonised service of social value appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Harmonised service of social value in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Harmonised service of social value is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2007 establishments in Europe, Emergency telephone numbers, Telephone numbers, so understanding it makes those chapters shorter.
In everyday life: Look for Harmonised service of social value outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
