Received a call from this number, electronic voice said it was Expedia and offered me $900 discount on travel. It gave me the option of being on a do not call list and I activated this. However, why is a company based in Washington State, USA using an area code (604) which is Vancouver/Burnaby British Columbia and the  437 prefix relates to the suburb I live in? I think they somehow are using this to fool us into believing it is someone we know when the call display comes up.
