The Name Rater NPC is located in a house northwest of the Slateport City Pokémon Center. You can access this NPC as soon as you reach Slateport, and he can change the nickname of any of your Pokémon – as long as you’re their Original Trainer (OT).
So any Pokémon you receive through trades can’t have their nicknames changed by the Name Rater.
Name Rater Location (Step-by-Step)
Slateport City is initially accessible from Route 109’s beach to the south. You’ll first get here right after you get through Dewford Town.
If you haven’t visited Slateport City yet, then make sure that you’ve done the following in your playthrough first:
- Obtained the second Gym Badge from Brawly, the Gym Leader in Dewford Town.
- Unlocked the option for Mr. Briney to take you to Route 109, which is near Slateport City.
Although once you unlock Fly it’ll be much easier to fly back to Slateport to meet with the Name Rater.
Once you’re ready, just head to Slateport City’s Pokémon Center to get started.
Step 1: From Slateport City’s Pokémon Center, follow the path on the left heading north.
Step 2: Then just look for the Name Rater’s house on the left-hand side of the path – it’ll be just below the Contest Hall.
Step 3: Once inside, you’ll find the Name Rater NPC standing next to a table.
Talk to him when you’re ready to rename your Pokémon.
What Does the Name Rater Do?
The Name Rater allows you to rename your Pokémon, adding a layer of personalization in your playthrough. You have the freedom to choose cool, cute, or even joke nicknames to your Pokémon – the choice is yours!
Using the Name Rater’s service is pretty straightforward.
Just approach him, select the Pokémon you want to rename, and then input the new nickname.
Keep in mind that nicknames can only be up to 12 characters long.
Tip: The Name Rater can only rename Pokémon for which you’re the Original Trainer (OT) and whose ID Number matches yours. As a result, traded Pokémon (including those from Wonder Trades and the GTS) are unable to be renamed. You can check a Pokémon’s OT and ID No. by viewing their summary screen.
If you try to rename a Pokémon that wasn’t originally yours, the Name Rater will kindly refuse, saying: “That is a truly impeccable nickname! I can’t say anything bad about it!”
