As it's already been mentioned, just make sure the phone and number is disposable to you. They've gotten stricter with roaming outside the U.S. where their phones may register on the network and work, but the ToS means you agree not to use it outside TracFone's service area. Some have had it work, then gotten cut off midway through their stay because TracFone's billing caught up with the roaming charges and they turned the phone off.

I don't want roaming charges on my postpaid family plan, and I don't want to risk bringing a TracFone only to have it shut off just when I need it.
