Manufacturers do not list the bolt patterns or any part numbers for pretty much anything when it comes to their trailers so you'll need to look for the serial number and RPO number that should be listed on your current pin box and we can use those to determine the bolt pattern.
If this sticker is missing or has been painted over then you can determine the bolt pattern with the help of the article I've attached below. This article will have you take some measurements and then gives you a chart to to plug the measurements into to find the bolt pattern.
For example, the Trailair Air Ride 5th Wheel Pin Box # LC155943 you referenced has an 1116 bolt pattern.
