Ottawa International Airport (YOW)
The 343 airport guide uses YOW as the practical travel anchor for Ottawa while making clear that the telephone code extends far beyond the airport's catchment. The page is about Ottawa access, not an airport-defined area-code boundary.
Ottawa International Airport (YOW)
Ottawa International Airport is the primary commercial airport for Ottawa. This guide explains the YOW airport code, where the terminal is and the main ground-transport options without treating the airport as the boundary of area code 343.
Ottawa International Airport
1000 Airport Parkway Private, Ottawa
YOW is Ottawa's principal passenger airport and the main airport result behind searches for Ottawa airport. It sits south of central Ottawa inside the city.
OC Transpo serves the airport with O-Train Line 4 from Airport station to South Keys and bus service including route 105. Taxis, rideshare, rental cars and other authorized ground transportation are also available.
Where Ottawa International Airport is
YOW is south of central Ottawa. The airport is an Ottawa travel hub, while area code 343 covers a much wider Eastern Ontario numbering geography.
YOW is the main Ottawa airport
Ottawa is used for practical local utilities because it is the largest city and dominant search anchor, while regional pages keep the wider Eastern Ontario scope visible. For most commercial air travel to Ottawa, YOW is the primary airport. The airport is south of central Ottawa and is connected to the city by road and public transport options.
Airport code and area code are different things
Ottawa is the strongest city reference, but the 343 geography extends through a much broader Eastern Ontario area that also includes centres such as Kingston, Cornwall, Belleville, Brockville and Pembroke. YOW is an IATA airport identifier, while 343 is a telephone numbering code. Searching for Ottawa airport code therefore refers to YOW, not to 343.
The airport does not define the whole 343 region
The code should be read as a newer layer over an existing regional numbering map, not as an Ottawa-only code created for one municipality. Area code 343 extends across Eastern Ontario, including communities far beyond Ottawa. YOW is included because Ottawa is the main city and travel hub associated with the search intent for this site.
Why these airports belong in the 343 guide
Ottawa is used for practical local utilities because it is the largest city and dominant search anchor, while regional pages keep the wider Eastern Ontario scope visible.
Airport coverage and telephone coverage are different
Ottawa is the strongest city reference, but the 343 geography extends through a much broader Eastern Ontario area that also includes centres such as Kingston, Cornwall, Belleville, Brockville and Pembroke. Airports are included because they are useful gateways for that geography, not because an airport catchment defines the border of area code 343.
Use the travel hub that matches the code's scale
The code should be read as a newer layer over an existing regional numbering map, not as an Ottawa-only code created for one municipality. This is why some area-code guides focus on one metropolitan airport system while province-wide guides need several gateways.
Codes answer different questions
343 was introduced in 2010 as an overlay on the long-established 613 region, adding numbering capacity across Eastern Ontario without dividing the territory. Airport identifiers such as YOW, YVR, YYZ or YTZ describe aviation facilities; 343 is a telephone numbering code. The two systems can overlap geographically without being interchangeable.
