Do Not Fret – Here Are Some Pro Tips If You Find You Are Missing LEGO® Pieces!
Listen, we have all been there. You are an hour or two into a build and you can’t find that small stud you swear you just saw in the LEGO® pile. You have followed the instructions, organized the bags, and still can’t find that little piece. Let’s go over some easy ways to fix this and what to do to make sure you never miss a LEGO® piece again!
Here Are Some Quick Tips And Tricks To Help You Find That Missing Piece And Get Back To Building
Check The LEGO® Box Before You Freak Out
It happens just as often as when your heart skips a beat. Sometimes, the little LEGO® piece is sitting inside the box. Grab yourself a flashlight to look inside. If you don’t care about the box, peel it open from all directions.
Look For Similar Pieces In Sets You Currently Own
Instead of spending the time searching and contacting LEGO® support, you can always substitute what you need with what you currently have. There is no shame in saving time and effort by turning to your own collection.
Check Under Furniture
Believe it or not, LEGO® pieces can sometimes roll or bounce off the table and end up on the floor or under furniture. Safely lift up furniture and shine a flashlight to see if the pieces fell underneath. Heck, you might find even more pieces you have misplaced from the past!
Finally, Use Online Brick Resources
LEGO® has a community of dedicated, insightful, and helpful fans who are ready, willing, and able to help you on public forums and answer your questions. If you are missing a piece and can’t find it anywhere, LEGO® Support is always happy to help!
How To Get Missing LEGO® Pieces Replaced For Free (Step By Step)
The good news is that LEGO® continues to stand behind their products with exceptional customer service. Their replacement parts service has streamlined the process significantly in recent years. You can request missing pieces directly through their website by providing your set number and the element ID (found in the instructions). While replacement times can vary depending on demand, LEGO® typically processes requests within a few weeks and ships them at no cost for genuinely missing pieces from new sets.
- Find the element ID. Flip to the last pages of your instruction booklet — the parts list shows every piece next to a 6- or 7-digit number. That’s the element ID. Every piece has one, like it’s in witness protection.
- Head to the replacement parts page on LEGO.com and choose the missing pieces option.
- Enter your set number, then punch in the element ID or pick the piece from the visual parts list.
- Confirm your shipping address and submit. There is no payment screen — genuinely missing pieces from new sets ship free.
- Watch the mailbox. LEGO® quotes roughly 10–14 business days for replacement pieces, and it can stretch longer around the holidays. There’s no tracking either — the pieces are hand-picked at the warehouse and dropped in a plain envelope.
One bonus: the same service replaces broken pieces too. So if one of those notoriously fragile brown pieces snapped in half mid-build, same flow — element ID, set number, free replacement.
Lost The Piece Yourself? Different Problem, Different Fix
Honesty time: the free replacement service is for pieces that were never in the box. If the piece went up the vacuum, disappeared into the couch cushions, or got carried off by the dog, that’s on us — and LEGO® knows it. The fix here is LEGO® Pick a Brick, where you can buy individual elements for pennies to a few dollars each. Search by the same element ID from your instruction booklet, add it to the cart, done. And if you want to never be stuck again, do what I do: keep a bulk LEGO® Classic tray on the shelf as a piece insurance policy. More on that below.
One Final Note On Missing LEGO® Pieces
Please ensure you exhaust all efforts and save yourself time and effort before reaching out to LEGO® Support for missing pieces. I would save them as a resource to be used sparingly. LEGO® very rarely misses pieces due to the quality assurance process the manufacturing plants have in place. If your set is missing a piece, it is most likely due to human error — so take a deep breath and look around for a bit before panicking.
This set here, LEGO® Classic 10717 (now retired), featured 1,500 brightly-colored pieces that could help fill in gaps for existing or new sets. While this particular set is no longer in production, the LEGO® Classic line continues to offer similar bulk brick collections perfect for having spare pieces on hand. I always have a few trays filled with miscellaneous pieces.
You always have options!
Frequently Asked Questions
Will LEGO® send missing pieces for free?
Yes. For pieces genuinely missing from a new set, LEGO® ships replacements completely free through their replacement parts service — no receipt required. You just need the set number and the element ID from your instruction booklet. The free service doesn’t cover pieces you lost yourself; that’s what Pick a Brick is for.
How long does it take LEGO® to send missing pieces?
LEGO® quotes roughly 10–14 business days for replacement pieces — call it two to three weeks in the real world. Around the holidays or during demand spikes it can run longer. There’s no tracking number since the pieces are hand-picked at the warehouse and mailed in a plain envelope, so resist the urge to refresh a tracking page that doesn’t exist.
Can you buy individual LEGO® pieces?
Yes — LEGO® Pick a Brick on LEGO.com sells individual elements, most for well under a dollar each. Search by element ID, color, or piece type. This is the route when you lost a piece yourself, need extras for a MOC, or want spares of a part you break often. BrickLink is the other big marketplace, especially for retired and rare elements.
What is a LEGO® element ID and where do you find it?
The element ID is the unique 6- or 7-digit number LEGO® assigns to every piece in every color. You’ll find it in the parts list on the last pages of your instruction booklet, printed next to the picture of each piece. It’s also listed on Pick a Brick product pages. That number is your ticket for both the free replacement service and buying individual pieces.
How often are LEGO® sets missing pieces?
Very rarely. LEGO®’s factories weigh every box and run tight quality assurance, so genuinely missing pieces are the exception, not the rule — which is why the piece is usually hiding in the box or under the couch. If a set arrives missing a lot of pieces, that’s a red flag: check whether the set is genuine LEGO® before blaming the factory.
