Alright, let me walk you through how I figured out the airport codes for Trinidad and Tobago the other day. It wasn’t super complicated, but you know how sometimes finding simple info takes a minute.

So, I needed these codes, was helping someone plan a potential trip, and they asked me point-blank. My first thought was, “Okay, easy enough.” I went over to my computer, sat down, and opened up my web browser like usual. Nothing fancy.
My first search was pretty basic. I just typed something like “airport code Trinidad and Tobago” into the search bar and hit enter. Naturally, a whole load of results popped up. Some looked like official airport sites, others were travel blogs, booking sites, you name it.
I started clicking through a few. Right away, I noticed mentions of two different main islands, Trinidad and Tobago, and it clicked that they might have separate airports, which means separate codes. Makes sense, right?
I focused on finding the main international airport first. The name “Piarco International Airport” kept appearing for Trinidad. And next to it, I consistently saw the code POS. Okay, seemed like the primary one for Trinidad.
Then I specifically looked for Tobago. The name A.N.R. Robinson International Airport came up for Tobago. The code associated with it was always TAB.

Just to be sure I wasn’t grabbing old info or mixing things up, I quickly checked maybe two or three different reliable-looking travel or airline sites. Didn’t want to give my friend the wrong details. They all confirmed the same thing.
So, the main codes I found are:
- For Piarco International Airport in Trinidad: POS
- For A.N.R. Robinson International Airport in Tobago: TAB
And that was pretty much it. Took a few minutes of searching and comparing, but got the job done. Just had to make sure I distinguished between the two main islands’ airports. Simple as that, really.
