Sideline is not supported in Canada at this time (meaning you cannot choose a Canadian phone number in Sideline nor create an account with a Canadian area code).
A valid US carrier phone number is needed to create a Sideline account.
However, you may make/receive calls to Canada if your carrier plan allows it.
Please Note: Any calls to/from Canada may result in long-distance fees depending on the plan you have with your carrier.
We do not support any MMS messaging to Canadian numbers at this time.
Please see our help center article for more information on your phone number and registration.
If you have any further questions, please submit a request.
