What is an IATA code?
The IATA code is how DHL sorts its packages. Each major DHL branch in the world has an IATA code associated with it. The DHL IATA codes look very similar to the IATA codes used for airports i.e. YYZ for Toronto or YVR for Vancouver. Branches close to the airports usually get the same IATA code as the airport. For example, the branch in Richmond BC is YVR because it is close to the Vancouver International Airport. However branches a little more removed get their own DHL made IATA code. For example, Burnaby BC is not close to an airport, so it has its own DHL IATA code which in this case is YCW. Having the correct DHL IATA code is very important. If the IATA code is incorrect, the package will be delivered to the wrong branch.
