Trinidad vs. Guyana (14 November 2017) has been considered only a practice match (=non-FIFA game), as it didn't get full sanctioning from FIFA:

I believe Jamaica vs. Trinidad (31 August 1997) should also be non-FIFA, as several foreign players suited up for Trinidad (but different, less strict times back then...)

Edit: According to the article above, the Grenada game (12 November 2017) then apparently was considered a full FIFA friendly (it's now as non-FIFA)
