Notes on Area 905
905-242 Oshawa is the first verified exchange that duplicates a 416 exchange.
416-242 was long a Toronto assignment. 416-983 also now exists as an active
exchange (905-983 is Orono).
On 4th October 1993, the new 905 area code was officially in effect, formed
from that part of the former 416 area outside Metropolitan Toronto. Bell
Canada announced that only Toronto exchange will retain the 416 area code.
This list, then, only indicates those numbers in 905. Toronto prefixes
(including cellular and pager) will be listed in the 416 chart.
Some potential pitfalls of the 905 area code are 1) that 905 used
to be the area code used to dial Mexico City (Mexico can now be
called under the overseas dialing setup); 2) 905 somewhat resembles
the adjacent area code 705 to the north thus risking other confusion;
3) at the time of assignment, other area codes such as 210 could have
been assigned which would provide faster rotary dialing; there were
few area codes left to be assigned in the traditional format in any
event, thus limiting the choices of area code.
This split will change the dialing of local calls that cross the Toronto
boundary ie. dial area code + local number if dialing a local call into
or out of Toronto (no 1 + is needed beforehand unless the call is indeed
long distance). The split will be completed 25 March 1994 (the end of the
"permissible" dialing period in which 905 may or may not be used for calls
outside Toronto).
In March 1990, the dialing system in 416 was changed to allow for NXX
codes (N is a digit from 2 to 8, X is any digit 0 to 9) from the previous
NNX prefix format. Basically, area codes style numbers may now be used
for exchanges. Some of these prefixes are already assigned in 905
territory, thus the area code 905 will have to be dialed for all long
distance calls within 905 (previously, just 1 + number had to be dialed
for long distance within an area code).
Note that exchanges like 514, 519, 613 were not assigned, and may never
be assigned since it may become necessary to use the area codes for
purposes of local dialing across area code boundaries. Indeed, since
416+number will be required to dial to Toronto from outlying local
exchanges, 416 would not be assigned as a regular service prefix,
nor would 905 since it may be useful to allow 905+number to be used
to complete local calls within 905 (ie. if it is not certain which
area code a call is starting from, dial area code + local number
anyway, and the call can be made).
Some exchanges in the 90X or 91X series may be assigned for WATS line
service as has been the case previous to the change to extra exchange
prefixes. The exact assignments are unknown at this time. Possible
mistakes resulting in calls to 911 may also be a factor in avoiding
new prefixes of the 91X form at this time (and 911 itself will not
become a prefix in ordinary service for obvious reasons).
Any blanks in the list mean the exchange is not in service as of last
report, or the exchange number is being used for some other unknown purpose.
There are sometimes things like billing codes used internally by Bell,
for instance. There may also be other exchanges for such things as cellular
telephones, pagers and test circuits that are not usually mentioned in phone
books, etc. An effort was made to list each exchange that appears to be
active, even if it is listed with question marks to mark an unknown status.
548 Hamilton is used for transit information services.
Thanks to Ray Chow (ray.chow@canrem.com) for some updates to the chart
effective the 17 February 1993 edition.
In addition, 645 Hamilton exchange is used for recorded messages,
broadcast station contest lines, ticket agencies, and other "mass calling"
purposes. These kind of lines can be called "choke" exchanges, to handle
conditions that can get very congested.
Federal government prefixes in 905 include Burlington (336),
Cooksville (277, 566, 675 (actually 675 is a Toronto (416) prefix)),
Hamilton 572, Malton (612, 670, 676).
Exchanges like 320 and 942 seem to be active from some places, but not from
others. These may be test exchanges, or exchanges to be activated in the
near future, or localised testing exchanges. It could also be a programming
error in a few telephone switches.
997 is an exchange used for numbers that will identify the telephone number
that is calling. 996 is used for some testing as well, but may need to be
dialed as 416-996-xxxx . 958 and 970 are used for other tests and are
accessed by dialing 1+905+ beforehand. 320 is a possible test exchange.
999 is sometimes used for testing; if so, the exchange will give another
dial tone when 999 + the number that's calling is dialed.
