Passport Book Vs. Card

passport card is for if you drive or float to another country the book is for if you are flying (they stamp the bookon entrance)

 

The card is good for land and sea travel between the u.s., Canada, Mexico and the Caribbean only. I use it when I go to Canada.

I suggest getting both. You can use the card to go to and from Canada while working, and if you fly out of the country you use the book.

If you can only afford one though, get the book. I just got the card last year (my company paid for it), and this year I went to the Dominican Republic on vacation. Long story short I sent my card off to get a book 2 months before leaving, and didn't get the book until 3 days before I left after a call to my congressman's office.

 

This might be a place to get more information as well. You can have both.

With the Passport Card you can drive into Canada,and Mexico.Just can't fly in and out.It is also used by people taking cruises as it is accepted at ports for boarding and returning.I don't know how it would work overseas.Not many carriers like to drive into Mexico but there are quite a few that go into Canada.

 

if you are travelling for pleasure, get the passport book and card. Use them where appropriate.

If you are travelling for business in a commercial vehicle, get a FAST card.
