Considered this option myself, the last time I had to renew my passport. After looking into it, frankly, I cannot understand why anyone would get a passport card. The price
difference is minimal and there is no meaningful benefit.
Yes, for now, it is a smaller card that will get you into a couple of nearby countries. But what if that changes? You used to be able to go in and out of those countries with just a drivers license
. Then 9/11 happened and they decided you needed more. What will they decide the next time something happens?
A regular passport works anywhere in the world. It makes no sense at all to have both a regular passport and a passport card. Given the limitations of the passport card, and the possibility that at some point in the future, some of the countries that now accept the card, could change there minds, I'm just not seeing it.
Get a regular passport.
