How Does a 905 Phone Number Work for Your Business?
A 905 area code business phone number operates under the North American Numbering Plan (NANP) and supports 10-digit dialing due to overlay codes 289, 365, and 742. This phone number allows your business to stay easily reachable across the Greater Toronto Area and surrounding communities, through mobile carriers, landlines, and VoIP phone services.
The dialing format for numbers in the 905 region requires 10-digit dialing. Local callers within the region dial the 905 area code followed by the 7-digit number, while long-distance calls within Canada or the U.S. use 1 + 905 + the number. International callers can reach numbers in this area using the format +1 (905) XXX-XXXX.
