The process has begun to figure out how to handle an expected phone number shortage in Nova Scotia and Prince Edward Island.
The two provinces share the 902 area code. By April 2015, however, there won't be any more numbers available, according to the CRTC.
The federal regulator announced yesterday that it has set up a committee to look at various options.
For example, Nova Scotia or P.E.I. could get its own area code. Or a new area code could be assigned to anyone setting up a new phone line in either province, which would mean 10-digit dialling.
Most provinces in Canada have two or more area codes. In some provinces, the new code is assigned to a particular region.
That's not the case in Manitoba or Saskatchewan, where the idea of regional area codes was rejected because too many customers would have had to change their phone numbers.
People in the same area — even the same street — could have different area codes.
In Atlantic Canada, New Brunswick and Newfoundland and Labrador each have their own area code.
