The Nationwide Wireless Priority Service (WPS) is a system in the United States that allows high-priority emergency telephone calls to avoid congestion on wireless telephone networks. This complements the Government Emergency Telecommunications Service (GETS), which allows such calls to avoid congestion on landline networks. The service is overseen by the Federal Communications Commission and administered by the Office of Emergency Communications (OEC) in the Department of Homeland Security. WPS was previously administered by the National Communications System (NCS) which had been created by President Kennedy by a Presidential Memorandum on August 21, 1963, and expanded by President Reagan by Executive Order 12472 on April 3, 1984. On July 6, 2012, President Obama signed Executive Order 13618, which eliminated the NCS as a separate organization; it was merged into the Office of Emergency Communications (OEC), which had been created in 2007. A ceremony to retire the colors of the NCS and to celebrate the legacy of the organization was held on August 30, 2012, in Arlington, Virginia.
During a local or national emergency, wireless telephone networks are likely to become congested with calls. Even absent emergencies, some towers and networks receive more calls than they can handle. WPS allows high-priority calls to bypass that congestion and receive priority by dialing *+272+DST_NUMBER+send (the 'star' key followed by 272 followed by the destination number followed by the dial key). The system is authorized only for use by national security and emergency preparedness personnel, classified into five categories:
Unlike the GETS system, which provides landline priority telephone calls, participation in the WPS system is optional for telephone companies. As such, support is only available on selected networks and usually requires additional fees for activation, availability, and use.
Before using the system, each user must receive authorization from the National Communications System and subscribe to the service with a participating provider. Once authorized, a user simply needs to prepend calls the vertical service code of "*272" to receive priority consideration on the wireless network.
Although the system is said to ensure a high probability of call completion, it is not without serious limitations. The WPS will not preempt calls in progress, so the user will have to wait for bandwidth to open. It is also not yet supported by all carriers. In order for a call to work, telephone infrastructure must be powered and functioning. Finally, a call that receives priority using WPS does not automatically get priority on landline networks. Therefore, congestion on the Public Switched Telephone Network may prevent the call from completion unless the user makes additional steps to access the GETS service for landline calls as well. Because of these and other limitations, the WPS explicitly does not guarantee call completion.
AT&T was the first to deploy this service with full functionality end to end.

911, sometimes written 9-1-1, is an emergency telephone number for Argentina, Canada, the Dominican Republic, Fiji, Jordan, Iraq, Mexico, Pakistan, Maldives, Palau, Panama, the Philippines, Sint Maarten, the United States, and Uruguay, as well as the North American Numbering Plan (NANP), one of eight N11 codes. Like other emergency numbers, dialing 911 for whatever purpose is a crime in most jurisdictions. Penalties for abuse or misuse of 911 can range from probation or community service to fines and jail time. Offenders can also be ordered to undergo counseling and have their use of telephones restricted or suspended for a period of time as a condition of probation.
Enhanced 911 is a system used in North America to automatically provide the caller's location to 911 dispatchers. 911 is the universal emergency telephone number in the region. In the European Union, a similar system exists known as E112 and known as eCall when called by a vehicle.
An emergency telephone number is a number that allows a caller to contact local emergency services for assistance. The emergency number differs 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; these often differ only by the last digit.
The Automatic Voice Network was a worldwide American military telephone system. The system was built starting in 1963, based on the Army's existing Switch Communications Automated Network (SCAN) system.
411 is a telephone number for local directory assistance in Canada and the United States. Until the early 1980s, 411 – and the related 113 number – were free to call in most jurisdictions.
A telephone call or telephone conversation, also known as a phone call or voice call, is a connection over a telephone network between the called party and the calling party. Telephone calls started in the late 19th century. As technology has improved, a majority of telephone calls are made over a cellular network through mobile phones or over the internet with Voice over IP. Telephone calls are typically used for real-time conversation between two or more parties, especially when the parties cannot meet in person.
A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls. For the calling party, a call to a toll-free number from a landline is free of charge. A toll-free number is identified by a dialing prefix similar to an area code. The specific service access varies by country.
111 is the emergency telephone number in New Zealand. It was first implemented in Masterton and Carterton on 29 September 1958, and was progressively rolled out nationwide with the last exchanges converting in 1988.
Mercury Communications was a national telephone company in the United Kingdom, formed in 1981 as a subsidiary of Cable & Wireless, to challenge the then-monopoly of British Telecom (BT). Although it proved only moderately successful at challenging BT's dominance, it led the way for new communication companies to attempt the same.
A public-safety answering point (PSAP), sometimes called a public-safety access point, is a type of call center where the public's telephone calls for first responders are received and handled. It takes calls from any landline, mobile phone line, or VoIP line. It can also happen that when 112 is dialed in then a logic is implemented by mobile or network operators to route the call to the nearest police station. Such call centers exist in most countries to answer calls to an emergency telephone number. Trained telephone operators are also usually responsible for dispatching these emergency services. Most PSAPs are now capable of caller location for landline calls, and many can handle mobile phone locations as well, where the mobile phone company has a handset to location system. Some can also use voice broadcasting where outgoing voice mail can be sent to many phone numbers at once, in order to alert people to a local emergency such as a chemical spill.
A landline is a telephone connection that uses metal wires from the owner's premises also referred to as: POTS, Twisted pair, telephone line or public switched telephone network (PSTN).

000 Emergency, also known as Triple Zero or Triple 0, and sometimes stylised Triple Zero (000), is the primary national emergency telephone number in Australia and Australian External Territories. The Emergency Call Service is operated by Telstra, and overseen by the Australian Communications and Media Authority (ACMA), and is intended only for use in life-threatening or time-critical emergencies.
International telephone calls are those made between different countries. These telephone calls are processed by international gateway exchanges (switches). Charges for these calls were high initially but declined greatly during the 20th century due to advances in technology liberalization. Originally they were placed via long-distance operators. The calls were transmitted by cable, communications satellite, radio, and more recently, fiber optics and Voice over Internet Protocol (VoIP). International direct dialling was introduced in the 1970s, so calls can be dialed by country code without an operator.
Area code 710 is a special area code in the North American Numbering Plan (NANP). It was reserved for the federal government of the United States in 1983 for emergency services. Since 1994, the area code has provided access for authorized personnel to the Government Emergency Telecommunications Service (GETS) in the United States, and the Canadian local exchange carriers, and cellular/PCS networks. Previously, it was a Service Access Code (SAC) in the Teletypewriter Exchange Service (TWX) for the northeastern part of the United States.
