Phone Number Formats to Call Ottawa from Singapore

In Canada, phone number formats are highly standardized with no variation across the country. As well, landline and mobile phone numbers are formatted exactly the same. It is not possible to tell, simply by looking at a Canadian phone number, whether it is a mobile or landline number - and it doesn't matter for dialing purposes.

All Canada phone numbers are 10-digits long and include a 3-digit area code and 7-digit local subscriber number. Increasingly, the same region may have multiple area codes. Local subscriber numbers are unique within an area code. Please check here for more information on Ottawa area codes.

Canada phone numbers may be written to include a leading ' 1 '. This ' 1 ' can serve as either the Canada country code for inbound international calls or as a national direct code for national long distance dialing in Canada.

If the Ottawa phone number you have does not contain the full 10-digit phone number, then you'll need to double check to find the correct number.
