The tagging feature in Pokémon Go makes it easier for you to organize your Pokémon collection, and keep track of all your favorite choices. Tagging your Pokémon is pretty straightforward, but you can customize the type of tags you use, their colors, and there’s a maximum amount you can make.
There are eight colors you can make your tags: Red, Blue, Green, Yellow, Orange, Purple, Grey, and Black. You first have the option to create the color when you initially create a tag, and you must confirm the tag’s name before finalizing it. Once you’ve done that, you can add multiple Pokémon to that tag from your collection.
For those who want to make multiple tags, you can make quite a lot of them. The maximum number of tags you can make on your Pokémon Go account is 100, so you can create multiple versions. For example, you can tag multiple Pokémon for one Great League battle group, and then make three more different iterations, each unique. The same goes for creating multiple raiding groups.
It’s likely that Niantic will expand the number of tags you can make, much like the number of Pokémon you can have in your storage. It’ll likely happen further down the line, though.
