Questions about Burlington numbers
What area code is Burlington?
Burlington has 4: 289, 905, 365, 742. All of them cover the same area, so a number can carry any of them.
Do I need to dial 10 digits in Burlington?
Yes. Where two or more codes overlay the same area, every local call needs the full ten digits.
Which carrier has most Burlington numbers?
Bell holds about 26% 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 742 a new area code?
It went into service in 2021 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 Burlington 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.
