Find any 742- phone number in Ontario

Ontario's 742 area code is part of the North American Numbering Plan (NANP), which is a system of telephone numbering for telecommunications, allowing both local and long-distance calls to be identified and billed across national and international lines. The NANP includes the U.S., Canada, and several Caribbean countries. Within the NANP, each country is divided into separate area codes or “Numbering Plan Areas” (NPAs), such as the 742 NPA.

Within Canada, an area code has jurisdiction over a geographic territory. The 742 area code is part of an overlay for a large region in Ontario, stretching from Chatham-Kent to Dunnville and from the Golden Horseshoe to the northern border. In the NPA 742, each number is specific to a particular locality. For example, a number with the prefix 742-000-000 may be assigned to a location in Burlington, while a number with the prefix 742-111-111 could be located in Hamilton.
