Trade (GO)
In Pokémon GO, players are able to trade with registered Friends. Both Trainers must be at least level 10 and have the required amount of Stardust to trade. Trades can only be initiated if both traders are within 40 kilometers of each other, and a player can make at most 100 trades per day.
Restrictions
The following Pokémon are ineligible for trades:
- Mythical Pokémon (except Meltan and Melmetal)
- Pokémon marked as favorites
- Current Buddy Pokémon
- Past Buddy Pokémon can be traded, but the player will receive a warning that all progress made in Buddy Adventure will be reset upon trade
- Shadow Pokémon
- Pokémon currently defending a Gym
- Pokémon not at full HP
- Pokémon that have previously been traded once before
Stardust costs
Every trade requires at least 
100 to execute.
Some trades are considered Special Trades, which usually require a lot more Stardust. Special Trades require the players to be Good Friends or higher, and only one Special Trade can be made per day. The following are considered special trades:
- Pokémon not already in the recipient's Pokédex (including alternate forms such as Unown or costumed Pikachu)
- Legendary Pokémon, Meltan, and Melmetal
- Shiny Pokémon
- Purified Pokémon
- If the Purified Pokémon is already registered in the recipient's Pokédex, trading does not cost additional Stardust, but still counts towards a Special Trade

Candy rewards
With each trade, players also receive Candy of the Pokémon that was traded away. The greater the distance between the locations where the two Pokémon were obtained, the greater the Candy yield. Trading also has a chance of yielding one Candy XL, which also increases with distance.

IV reroll
The IVs of the traded Pokémon are randomly regenerated during the trade. If trading to a player with a lower Trainer level, the traded Pokémon's Power Up level will decrease to the player's limit (Trainer level + 2 or 5). A traded Pokémon's Power Up levels will also be rounded down, so a Pokémon that's been powered up to level 20.5 will be lowered to level 20 when traded. The minimum possible IVs for traded Pokémon slightly increase with Friendship level.
- Good Friends are guaranteed at least 1 IV for each stat
- Great Friends are guaranteed at least 2 IVs for each stat
- Ultra Friends are guaranteed at least 3 IVs for each stat
- Best Friends are guaranteed at least 5 IVs for each stat
- Lucky Friends are guaranteed at least 12 IVs for each stat
Lucky Pokémon
During a trade, there is a small chance that both traded Pokémon will become Lucky Pokémon. Lucky Pokémon guaranteed at least 12* IVs in each stat and require half the amount of Stardust to Power Up. A Lucky Pokémon is indicated by a shimmery effect in the Pokémon Box and the Pokémon's profile. Like with Shiny Pokémon, the Pokédex will record the number of Lucky Pokémon the player has obtained for that species.
The probability of obtaining a Lucky Pokémon depends on how long the Trainer has had that Pokémon in storage at the time of trade, and it is based on the older of the two Pokémon traded. The following is the observed probability of traded Pokémon becoming Lucky:[1]
- 5% for Pokémon obtained less than 1 year ago
- 10% for Pokémon obtained between 1 and 2 years ago
- 25% for Pokémon obtained more than 2 years ago
- 75% for Pokémon obtained between July to August 2016
- Since September 5, 2018, these Pokémon are guaranteed to be Lucky, provided that at least one of the players has not already accumulated ten Lucky Pokémon
Since April 2019, players who are Best Friends have a chance of becoming Lucky Friends, which guarantees the next trade to result in Lucky Pokémon. This can possibly be triggered by performing a task that may increase Friendship level, such as opening a Gift or trading a Pokémon, on the first interaction of the day. After completing a trade with a Lucky Friend, the players will return to Best Friend status.
