The area code 905 serves a region in the United States, but it is more prominently associated with an area in Canada, specifically in Ontario. In terms of the United States, the area code 905 itself is not used. However, I can provide a breakdown of the geography and information for both the U.S. and Canadian regions associated with this code.
1. Canada (Ontario) – Primary Use of Area Code 905
Area code 905 is primarily associated with Southern Ontario, Canada, not the United States. It includes a wide range of cities and towns in the Greater Toronto Area (GTA) and surrounding regions. The specific areas it covers include:
- Hamilton
- Burlington
- Oakville
- Mississauga
- Markham
- Richmond Hill
- Vaughan
- Ajax
- Pickering
- Newmarket
- Aurora
- Georgina
The area code 905 is one of the original area codes created in 1947, though as the population in Ontario grew, some regions now use different area codes, such as 416, 647, 289, and others.
2. Overlapping U.S. Area Codes
While area code 905 is not used in the U.S., it is geographically close to parts of the U.S.-Canada border. For example, cities like Buffalo in New York state and parts of Michigan are close to the Canadian province of Ontario, but these areas use U.S. area codes like 716 (Buffalo) or 734 (Ann Arbor, Michigan).
Conclusion
In summary, the area code 905 is primarily for Ontario, Canada, and not used within the United States. However, areas of the U.S. near the Canadian border, such as parts of New York and Michigan, are geographically close to where area code 905 is used in Ontario.
