Short answer: no. A Lucky Egg doubles XP and a Star Piece doubles Stardust gains for 30 minutes - neither does anything else. Every breakdown of what sets Lucky trade or Lucky Friends odds names the same handful of factors: how long you've owned the Pokémon, and (for Lucky Friends) Best Friend status plus a daily roll. Items never appear on that list, in any source.

Does a Lucky Egg or Star Piece improve your odds of a Lucky trade in Pokémon GO?
It's an easy myth to believe: popping a Lucky Egg before a big trading session "feels" like it should help, especially since the item has the word Lucky right in its name. It doesn't - here's what the item actually does, and what actually moves the needle on a Lucky trade.
What Lucky Egg and Star Piece actually do
Both are time-limited boost items, and neither touches trading at all:
- Lucky Egg - doubles XP gained from everything (catches, Pokéstops, evolutions, trades) for 30 minutes.
- Star Piece - doubles Stardust gained from everything for 30 minutes.
That's the entire effect. Neither item has a documented interaction with trade mechanics, friendship points, or Lucky odds of any kind.
What actually sets Lucky trade odds
Trading a Pokémon has a chance to turn it (and the one you receive) into a Lucky Pokémon - with a guaranteed-high IV floor and a steep Stardust discount on future power-ups. The factors that community research and official mechanics breakdowns consistently point to are:
How long you've had the Pokémon is the one factor every source agrees on - Pokémon you caught longer ago trade for better odds than ones you just caught. Niantic hasn't published an exact formula, community-tracked numbers vary between sources, and some older guides also claim friendship level shifts the odds while others describe the random Lucky roll as independent of friendship entirely - sources disagree on that second point, so this guide isn't going to pretend there's a settled answer. What every source does agree on, regardless of which side of that disagreement they land on: no item changes any of it. Not Lucky Egg, not Star Piece, not Incense - nothing you carry or activate shows up in a single breakdown of what sets a trade's Lucky odds.
What actually sets Lucky Friends odds
Lucky Friends is a separate, stronger mechanic: once two trainers hit Best Friends, each day's first qualifying interaction has a small chance (community estimates cluster around 1-3%) to flip both of you into Lucky Friends status, which guarantees your next trade turns both Pokémon Lucky - no age or friendship-level roll involved at that point, because the guarantee already fired. Again, no item shortens the climb to Best Friends or improves that daily roll; the only documented shortcut is the seasonal Lucky Trinket, a GO Pass Deluxe item that's a completely different thing from a Lucky Egg or Star Piece.
Why the myth persists
Lucky Eggs and Star Pieces are popular during exactly the moments trainers are already trading a lot - Community Day, a Friendship Friday, a big meetup with international friends. Activating a boost right before a trading session is good practice for the XP and Stardust alone, so when a Lucky Pokémon pops out of that session, it's easy to credit the item instead of the Pokémon's age or the friendship level that was already climbing in the background.
Don't waste the items chasing Lucky odds
Pop a Lucky Egg or Star Piece for what they're actually good for - stacking XP during a big session or clearing a Stardust-heavy evolution line - not in hopes of a better trade. If you're building toward Lucky trades or Lucky Friends, the only levers that matter are time (how long you've held the Pokémon, how long you've been friends) and keeping your friend list active. A fresh trading partner helps more than any item: grab a new friend code with one tap, or browse codes by country if you want to diversify who you trade with.
FAQ
Does using a Lucky Egg during a trade increase my chance of a Lucky Pokémon? No. It doubles XP gained from the trade, nothing else.
Does a Star Piece help with Lucky Friends? No. Star Pieces only double Stardust gains. Lucky Friends depends on Best Friend status and a daily roll, not any item.
Is there any item that improves Lucky trade odds? Not for a regular trade. The only item that affects Lucky status at all is the Lucky Trinket, and it works differently - it guarantees a Lucky Friends trigger with a Great Friend or higher, it doesn't boost the odds of an ordinary trade.
So what should I actually do to get more Lucky Pokémon? Trade older Pokémon when you can, keep your Best Friends active daily to climb toward Lucky Friends, and use the Lucky Trinket when you have one. Items that boost XP or Stardust are worth using for exactly that - just not for this.
