Phone number ownership in Canada can be looked up using reverse phone number lookup tools such as Canada411 or Yellow Pages reverse lookup services. These databases allow you to enter a full 10-digit Canadian phone number to find information about the owner, whether it is a residential number, a business number, or a service provider. They can also provide details like the city or province of origin and the phone company associated with the number (e.g., Telus, Bell, Rogers). If the number is not listed, they may provide general information based on the area code and prefix. Canada phone numbers have the country code +1 and follow a 10-digit format (NXX-NXX-XXXX), where N is 2-9 and X is 0-9. For direct and specific reverse lookup, websites like Canada411 and other related directories are recommended to identify the owner of a Canadian phone number accurately.
