History of the area code

A previous version of the +1-905 area code was once used as a block of alternate numbers for calls from the United States to Mexico (+52-5-...) in the days when overseas calls otherwise would have needed to be placed through a telephone operator. This use became obsolete with the widespread introduction of direct dial overseas calls and was completely abolished no later than February 1, 1991. By October 1992, the 905 NPA had been assigned for use resultant from the geographical split of the 416 area code. A telephone operator at work on a private switchboard A telephone operator is either a person who provides assistance to a telephone caller, usually in the placing of operator assisted telephone calls such as calls from a pay phone, collect calls (called reversed-charge calls in the UK), calls which... A direct dial call is a telephone call placed by the person making the call. ... February 1 is the 32nd day of the year in the Gregorian Calendar. ... 1991 (MCMXCI) is a common year starting on Tuesday of the Gregorian calendar. ...

The split from 416 occurred at 02:00 on October 2, 1993. Switching systems were programmed to accept permissive dialling in the new 905 code until 02:00 on March 26, 1994, during which time calls using the old area code would resolve to the proper central office code terminating in the new 905 NPA. Subsequently, failure to use the correct area code results in calls routed to an intercept system, which notifies the caller of the error. October 2 is the 275th day (276th in leap years) of the year in the Gregorian Calendar, with 90 days remaining. ... 1993 (MCMXCIII) is a common year starting on Friday of the Gregorian calendar and marked the Beginning of the International Decade to Combat Racism and Racial Discrimination (1993-2003). ... March 26 is the 85th day of the year in the Gregorian Calendar (86th in leap years). ... 1994 (MCMXCIV) was a common year starting on Saturday of the Gregorian calendar, and was designated the International year of the Family. ...

Automatic number identification (ANI) on the NPA's switching systems began transmission on October 11, 1992 for some central office codes, and full conversion was achieved by January 1, 1994. October 11 is the 284th day of the year (285th in leap years). ... January 1 is the first day of the calendar year in both the Julian and Gregorian calendars. ...

Only five years after its introduction, and with the proliferation of cell phones, fax lines, and secondary phone lines for home dial-up internet use, the NPA was exhausting numbers at a much faster rate than anticipated. By 1999, the CRTC had estalished an ad-hoc committee to study NPA relief planning for area code 905. A split of the 905 NPA was considered, with various options presented:

• a geographic split by municipality (either two-way or three-way)
• a geographic split of concentric rings around Toronto
• re-aligning NPA boundaries (some areas retain 905, others acquire a new NPA); that is, a municipality and exchange split
• a distributed overlay

The first three options would allow for either 7- or 10-digit dialling, whereas the latter required 10-digit dialling exclusively. The latter option was chosen because it was easier to implement technically, and required no changes for existing customers in the 905 area. The 289 NPA overlay was approved by the CRTC on August 15, 2000 (Order CRTC 2000-772), came into service on April 7, 2001, and was in full operation by June 9, 2001.

June 9 is the 160th day of the year in the Gregorian calendar (161st in leap years), with 205 days remaining. ...

905 officially became exhausted in November, 2005. All new central office prefixes will be assigned in NPA 289, as there are no longer any available prefixes in 905. For other uses, see November (disambiguation). ... 2005 (MMV) is a common year starting on Saturday of the Gregorian calendar. ...
