About 742 Area Code
Area code 742 serves Hamilton and the broader Golden Horseshoe region of southern Ontario, Canada. Activated on October 16, 2021, it was introduced by the Canadian Radio-television and Telecommunications Commission (CRTC) as a distributed overlay for the existing 905, 289, and 365 area codes. The 742 numbering plan area covers a densely populated corridor that wraps around the western end of Lake Ontario, including major cities such as Mississauga, Brampton, Oakville, Vaughan, Markham, Oshawa, Burlington, St. Catharines, and Niagara Falls. It is the fourth area code assigned to this region, reflecting the scale of demand for new phone numbers driven by sustained population and business growth.
The Golden Horseshoe is one of the most economically productive regions in North America, anchored by Hamilton's long history in steel and advanced manufacturing and surrounded by the GTA's financial, logistics, and technology sectors. Hamilton itself has been diversifying rapidly, with health sciences, post-secondary education (McMaster University and Mohawk College), and logistics emerging alongside its traditional industrial base. Businesses operating in Peel, York, Halton, Durham, and Niagara regions use local 742 numbers for customer outreach, appointment scheduling, B2B coordination, logistics dispatch, and multichannel support. A local southern Ontario area code consistently outperforms toll-free numbers on answer rates when targeting residents in these communities.
FoneSwift lists live 742 number inventory on this page with clear capability labels for Voice, SMS, and MMS support. Because 742 is a relatively new overlay (launched in 2021), availability tends to be better than older, more depleted codes like 905. If a specific 742 number isn't in stock at the time you search, the overlay codes 905, 289, and 365 cover the same geographic footprint, so any of those can deliver an equivalent local presence for the same region.
If your business is targeting Hamilton or the broader southern Ontario market, publish your number in both local and E.164 formats, for example (742) 555-1234 and +1 742 555 1234, and register A2P messaging traffic with Canadian carriers if you plan SMS campaigns. For number porting, refer to our porting guide; Canadian geographic numbers are portable between carriers in most cases. Many businesses keep their existing number when switching platforms to preserve continuity with established customers.
10-digit dialing is required for all local and long-distance calls within and into the 742 region. Register A2P messaging with Canadian carriers for business SMS campaigns to comply with carrier rules.
Area code 742 operates on Eastern Standard Time (EST, UTC-5) in winter and Eastern Daylight Time (EDT, UTC-4) in summer. Ontario observes Daylight Saving Time, switching in March and November.
Because 742 is an overlay, callers in the region are equally familiar with 905, 289, and 365 numbers. Any of these four codes signals a credible southern Ontario local presence. If 742 inventory is limited, consider 289 or 365 for the same geographic reach.

Fourth overlay for 905

The "905 belt" identity
The region covered by 742 is often called "the 905" by Canadians, a cultural shorthand for the suburban communities ringing Toronto. It's one of the few area codes with a widely recognized regional nickname.
Waterfall city
Hamilton is known as the Waterfall Capital of the World by some enthusiasts, with over 100 waterfalls and cascades along the Niagara Escarpment within city limits.
Exhaust-driven creation
The CRTC approved 742 in Telecom Decision 2020-362 after forecasts showed the 905/289/365 complex would run out of available numbers. A fifth code, 537, has already been reserved for future relief of this same region.

How Does Local 742 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 742 number in Hamilton and Ontario, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.
The typical parts of a Canada local number are:
- Country code (+1): identifies Canada for international routing.
- Area code (742): directs the call to the Hamilton / Ontario region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
Example formats:
| International Format (E.164) | +1 742 555 1234 |
| Local Format (National) | (742) 555-1234 |
