How to Clean Your Pokemon GO Storage

Step-by-Step Guide to Safe Mass Transfer

Running out of Pokemon storage? You're not alone. With over 900 species, events adding costumed variants, and Community Days flooding your box, storage management is one of the biggest challenges in Pokemon GO. This guide teaches you a systematic approach to clearing space without accidentally transferring something valuable.

The Philosophy: Tag First, Transfer Last

The biggest mistake players make is going straight to transferring. They search for low-IV Pokemon and start deleting — then realize too late that they just transferred a rank 1 PvP Pokemon or a Shadow Mewtwo.

The safe approach is the opposite: tag everything you want to KEEP first, then transfer what's left.

  1. Tag — Systematically tag every Pokemon worth keeping
  2. Review — Look at what's untagged to spot anything you missed
  3. Transfer — Only transfer untagged Pokemon, knowing your keepers are safe
💡 Why Tags? Pokemon GO's tag system (available from Level 14+) lets you create up to 100 custom labels. Tagged Pokemon are easily searchable with #tagname, and you can search for untagged Pokemon with !#. Tags are the foundation of the systematic cleanup workflow.

Before You Start: Create Your Tags

Open Pokemon GO, go to your Pokemon list, tap the tag icon, and create these tags:

Tag NamePurpose
KEEP_LUCKYHundos, shinies, luckies, legendaries, mythicals, Ultra Beasts
KEEP_MECHPokemon with Mega, Dynamax, Gigantamax, or Fusion investment
KEEP_PVPPvP battlers for Great, Ultra, and Master League
KEEP_RAIDTop raid attackers by type
KEEP_DEXPokemon to evolve for new Pokedex entries
KEEP_XPCheap evolves stockpiled for XP grinding

These tag names are exactly 20 characters or less (the tag character limit) and match what POGO Cleanup generates search strings for.

The Cleanup Workflow

1 KEEP LUCKY — Protect Your Irreplaceables

Search for: 4*,lucky,shiny,legendary,mythical,ultrabeast

Tag all results as KEEP_LUCKY. These are your most valuable and irreplaceable Pokemon — hundos, shinies, luckies, legendaries, and mythicals. Protect them first so nothing else in the process can touch them.

Why this is Step 1 A shiny Shadow Mewtwo or a lucky hundo Metagross cannot be obtained again. By protecting these first, every subsequent step can safely ignore them.

2 KEEP MECH — Protect Your Investments

Search for: dynamax,gigantamax,mega1,mega2,mega3,fusion

Tag all results as KEEP_MECH. If you've spent Mega Energy, Max Particles, or Fusion materials on a Pokemon, you don't want to lose that investment.

3 KEEP PVP — Protect Your PvP Teams

This is the trickiest step because different leagues want different IVs:

  • Great League & Ultra League: Search for top PvP families with attack0-2&defense13-15&hp13-15
  • Master League: Search for top ML families with 4* or 3*,4*

Tag all results as KEEP_PVP. For more on why low Attack is good for PvP, see our PvP IV guide.

Which families are "top PvP families"? This changes with each meta shift. POGO Cleanup maintains an updated list sourced from PvPoke rankings and generates the search strings for you, so you don't have to memorize the meta.

4 KEEP RAID — Protect Your Raid Teams

Search for the best raid attacker families by type with quality gates like 3*, 4*, shadow, or lucky.

Tag all results as KEEP_RAID. The top raid families include species like Machamp (Fighting), Metagross (Steel), Salamence (Dragon), Swampert (Water), and Mamoswine (Ice).

💡 Shadow Pokemon for Raids Shadow Pokemon get +20% Attack. Even a low-IV Shadow of a top raid species often outperforms a non-Shadow hundo. Keep Shadow versions of top raid attackers regardless of IVs!

5 KEEP DEX — Find New Pokedex Entries

Search for: evolvenew

Tag results as KEEP_DEX. These Pokemon can be evolved into species you haven't registered in your Pokedex. Evolve them through the complete chain (e.g., Pidgey → Pidgeotto → Pidgeot) before doing anything else with that family's candy.

6 KEEP XP — Stockpile Mass Evolves

Optionally, tag cheap-to-evolve Pokemon (12-candy species like Pidgey, Caterpie, Weedle, Wurmple) as KEEP_XP for mass evolving with a Lucky Egg. Only do this for families where your Pokedex is already complete.

Each evolution gives 1,000 XP (2,000 with Lucky Egg, 4,000 during 2× evolution events). You can fit ~70 evolves in one Lucky Egg window.

7 REVIEW — Last Safety Check

Search for: !# (all untagged Pokemon)

This shows everything that didn't get a KEEP tag. Scroll through and look for anything you want to save — a rare costume, a traded Pokemon with sentimental value, a species you might need later.

⚠️ Check for Legacy Moves Before transferring, search @special to find Pokemon with legacy or Community Day moves. These cannot be re-learned normally and may have significant value for PvP or trading.

8 TRANSFER — Clear the Rest

Search for: !# (untagged Pokemon)

Select and transfer. Because everything valuable is tagged, only expendable Pokemon remain. The game also has built-in protections — it won't let you mass-transfer shinies, luckies, or certain mythicals.

🛑 This is permanent! Transferring sends Pokemon to Professor Willow and cannot be undone. You get 1 candy per transfer. Always double-check before confirming.

The XP Evolve Trick

Before transferring cheap-to-evolve species (Pidgey, Caterpie, Weedle, Wurmple), consider mass-evolving them with a Lucky Egg for XP. Each evolution gives 1,000 XP base (2,000 with Lucky Egg). The 12-candy species are most efficient — you get the most evolves per candy.
