What is the city code for Richmond, British Columbia, Canada?

The city code for Richmond, British Columbia, Canada, is correctly identified as YVR. This code represents Vancouver International Airport, which serves Richmond and is the primary airport in the region. Although Richmond has its own municipal identity, its proximity to Vancouver makes YVR the relevant airport code for travelers heading to or from Richmond.

In contrast, the other options correspond to different locations: YYJ is the airport code for Victoria International Airport, GST is not a recognized airport code, and YWG represents Winnipeg James Armstrong Richardson International Airport. Thus, YVR is the relevant airport code for those traveling to Richmond, which cements its status as the correct answer.
