Cochrane area codes
Cochrane, Alberta is served by 3 area codes: 403, 587 and 825. They overlay the same geography, so local calls take all ten digits regardless of which code a number uses. 403 carries the most numbers – 7 of the 15 number blocks assigned in the exchange, about 47%. The newest of them, 825, went into service in 2016. Telus holds the largest share at 27%, followed by Freedom 20%, Other 20%.

Questions about Cochrane numbers
What area code is Cochrane?
Cochrane has 3: 403, 587, 825. All of them cover the same area, so a number can carry any of them.
Do I need to dial 10 digits in Cochrane?
Yes. Where two or more codes overlay the same area, every local call needs the full ten digits.
Which carrier has most Cochrane numbers?
Telus holds about 27% of the number blocks assigned here. This is share of blocks allocated by the Canadian Numbering Administrator, not share of customers – people keep their numbers when they switch carriers.
Is 825 a new area code?
It went into service in 2016 as an overlay, meaning it was added to supply new numbers in the same area rather than replacing the existing codes.
Is a call from a Cochrane number safe?
The area code tells you nothing about that. Spam callers routinely fake the number they display, often choosing a local-looking one because it gets answered more often. Look up the full number instead.
