My insurance carrier faxed me a "Canada Non-Resident" ID card.
Just got off the phone with GEICO agent, who tells me (after checking with supervisor) that such a card IS required and that they cannot fax or e-mail me the ID card, since it MUST be on a special paper to be recognized by Canadian officials (presumably RCMP or other LEOs). So, she's overnighting me the card (hopefully to be here by tomorrow), and if for any reason I don't get it by end of day tomorrow (Friday), to call them and make arrangements to get it at one of their offices on our way north (like maybe Coeur d'Alene first thing Monday morning?).
I specifically mentioned that I had a friend (referring to you, Mike) whose insurer I did not know, who had gotten one faxed. That sent her to the supervisor, and she came back to tell me that she was sure that was an error due to the paper it had to be on.
Just reporting the issue is all.
