The telephone number 3-1-1 is a special telephone number supported in many communities in Canada and the United States. The number provides access to non-emergency municipal services. The number format follows the N11 code for a group of short, special-purpose local numbers. The number 3-1-1 is intended in part to divert routine inquiries and non-urgent community concerns from the 9-1-1 number which is reserved for emergency service. A promotional website for 3-1-1 in Akron described the distinction as follows: "Burning building? Call 9-1-1. Burning Question? Call 3-1-1." Many cities also accept 3-1-1 comments through online interfaces. An ''Open 311'' application programming interface is also available for these services. ==History== The first use of 3-1-1 for informational services was in Baltimore, Maryland, where the service commenced on 2 October 1996. 3-1-1 is intended to connect callers to a call center that can be the same as the 9-1-1 call center, but with 3-1-1 calls assigned a secondary priority, answered only when no 9-1-1 calls are waiting. This system is intended to extend the system such that true emergency callers are answered quickly with highest priority. The largest 3-1-1 operation in North America operates in Toronto, which was implemented in 2009.〔http://findarticles.com/p/articles/mi_hb6642/is_5_25/ai_n45060498/〕 The Canadian Radio-television and Telecommunications Commission (CRTC) reserved the use of 3-1-1 for non-emergency municipal services throughout Canada on 5 November 2004. The first Canadian 3-1-1 service opened in Calgary, Alberta on 18 May 2005. Historically, the 311 code was used by some telephone companies for testing purposes. In Alberta, 311 was the automatic number announcement circuit (ANAC) until 1 April 2005 when this was changed to 958-6111 to make way for the 3-1-1 service. In the United States, 311 was sometimes used as a fictitious area code in Bell System advertisements depicting telephones; often the phone in the advertisement would bear the specific number ''Area Code 311 555-2368.'' This fictitious phone number was used in the 1979 horror film ''When a Stranger Calls''; in the opening of the television series ''The Rockford Files''; in the 1984 film ''Ghostbusters''; and on two episodes of the second season of the TV series ''Mission: Impossible'': episode 22 titled "The Killing" (on the killer's phone) and, fourth season, episode 12, titled "Time Bomb" (on a phone at a nuclear plant in a fictitious country). This number is also seen on the phone in ''Mister Ed'' during shots where the talking horse dials the phone using a pencil in his mouth. 311 555-2368 was also used in numerous episodes of ''The Bionic Woman'' as the private phone number of Jaime Sommers in her coach house. At the end of a 1963 episode of ''Route 66'', titled "Kiss the Monster, Make Him Sleep," Linc calls his estranged father at a number having area code 311. The number 311-555-9845 was used for a radio station hotline in episode 1, season 1, of the TV show ''A.L.F''. This area code is also used as the area code for Sunnyvale, California (which is actually 408) in the 1983 movie ''WarGames'' during the "war dialing" sequence where the main character is searching for a video game company's modem pool. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「3-1-1」の詳細全文を読む スポンサード リンク
