In a nutshell, proof helps to ensure that a Pokémon has been legitimately obtained. Certain high value Pokémon will require proof to be traded around in the PS! Wi-Fi room. The detailed list of which Pokémon require proof can be found below.

About IV spreads:

Optimal IV spreads are either defined as perfect or flawless. In most cases, the amount of significant IVs a Pokémon has will determine if it requires proof, along with other variables like shiny status and general rarity/exclusivity.

• Perfect - A spread that has 6 significant IVs.
• Flawless - A spread that has IVs that have been optimized for competitive battle.
• Significant - Values of 0, 30 & 31 (Values of 1 in Generation 7 or earlier as well)

IV spreads are listed in the following order HP/ATK/DEF/SPA/SPD/SPE. An unknown value can be listed as X in tradesheets, giveaway forms, etc.

Examples of "perfect" & "flawless" spreads:

Physical Attackers:

• 31/31/31/0/31/31 | 6IV Perfect physical attacking IV spread.
• 31/31/31/0/31/0 | 6IV Perfect physical attacking Trick Room IV spread.
• 31/31/31/x/31/31 | 5IV Flawless physical attacking IV spread.
• 31/31/31/x/31/0 | 5IV Flawless physical attacking Trick Room IV spread.

Special Attackers:

• 31/0/31/31/31/31 | 6IV Perfect special attacking IV spread.
• 31/0/31/31/31/0 | 6IV Perfect special attacking Trick Room IV spread.
• 31/x/31/31/31/31 | 5IV Flawless special attacking IV spread.
• 31/x/31/31/31/0 | 5IV Flawless special attacking Trick Room IV spread.

Unique Examples:

• 0/0/0/0/0/0 | Meme spread, typically found on Ditto; this would contribute a total of 6 perfect IVs. A flawless (0/1/30/31) IV in any spot contributes towards the max IV total.
• 31/31/15/x/31/0 | 5 perfect IVs + Lonely nature; Trick Room Stakataka optimized for Beast Boost to boost Attack.
• 3/3/3/3/3/3 | 6 perfect Effort Levels in Legends: Arceus. An effort level value of 3 after initial capture is the same as a full 31 IV.
