NOA Lot Check is a Nintendo of America subsidiary that checks over games made by first and third party publishers to make sure they're in compliance with Nintendo of America's guidelines. Occasionally they are mentioned in a game's credits, but this is very rare.
To launch a game on the eShop, companies must submit a copy to them to then be sent to NCL for later checking before the game is finally put on the eShop depending what the publisher chooses for the release date.
