This IL provides industry notification of the impending split of the 416 NPA.
(Includes safety liability disclaimer (if applicablc), ordering information, originator's signatu~ information)
We have been advised by Bell Canada that substantial telephone number growth in the Toronto area
necessitatessplitting the existing 416 NPA (area code) and the simultaneous introduction of a new 905 NPA
Both NPAs will have interchangeablecentral office codes (i.e., the second digit of a central office code may
be any digit 0-9).
The new 905 NPA will serve the area surrounding Metro Toronto and will include cities such as Mississauga,
Hamilton, Oshawa, and Niagara Falls. The 416 NPA will continue to serve the six boroughs that comprise
Metro Toronto (i.e., Toronto, Scarborough,York, North York, East York, and Etobicoke).
The split of the 416 NPA is scheduled for 2:00 AM Eastern Standard Time., Saturday, October 2,1993. There
will be a permissive dialing period starting 2:00 AM Eastern Standard Time, Saturday, October 2, 1993 and
ending at 2:00 AM Eastern Daylight SaVingsTime, SaturdayMarch 26, 1994. During the permissive dialing
period either 416 or 905 will be acceptable in a dialed number terminating in the new NPA. After the
permissive period, calls dialed with incorrect NPA codes will be routed to intercept.
r::!
A"Will begin transmitting "905" in the calling number Automatic Number
Switching systemsin the new 9O
Identification (ANI) on October 1, 1992.1All ANI changeswill be completed by January 1, 1994.

Test calls to verify routing to the ~~~ NPA can be made by calling 905-206-0000. This test number will
become available on September 1, 1993, and remain operational for a minimum of 30 days after the end of
the permissive period.
The attached map illustrates the 416 and 905 configuration after the split. A listing of, the communities to be
served by each area code after the split is also attached.
Canadian routing information is not included in Bellcore's LERG. Bell Canada will be mailing a list of 416
and 905 NXXs to its customers.
