How to use it

Build a missing-parts list from a set inventory, then copy it into a LEGO request or shopping list.

Set checklist

  1. Enter a set number (e.g. 10300-1) and load its full parts list.
  2. Check off each part you are missing and adjust quantities.
  3. Copy the list and paste it into a LEGO request, Pick a Brick or a BrickLink wanted list.

Photo identify

  1. Switch to the Photo tab if you have the loose piece in hand.
  2. Upload or snap a photo to identify the part number first.
  3. Use the part page or Set Finder to confirm color and quantity.

How to find a missing LEGO piece

Most missing LEGO pieces turn out to be small parts hiding in a bag, under the table or stuck to another piece. Before you order a replacement, work through these steps so you ask for the right part in the right color.

  1. Find the set number. It is printed on the box and on the front of the building instructions, for example 10316 or 75192. Lost the instructions? LEGO keeps them online on its building instructions page.
  2. Check it is really missing. Count the piece in the step where it is used, and remember that LEGO adds extra small pieces to many sets, so a leftover part is not always a mistake.
  3. Load the set's parts list. Enter the set number in the finder above. You get every part in the set with its color and how many the set contains.
  4. Match shape and color. Many pieces come in similar shades, such as light and dark bluish gray, so compare the color swatch with the picture in your instructions.
  5. Mark it and set the quantity. Tick each missing piece, adjust the count, and copy the list. You can paste it straight into a LEGO request or a shopping list.

Only have the loose piece, with no set number? Identify the LEGO piece by photo or check its underside to get the part number first.

Example: Lord of the Rings: Rivendell (10316-1) has 6,181 pieces spread over 898 different part-and-color combinations. Open its parts list and you can search the whole inventory instead of paging through the instruction booklet.

How to get missing LEGO pieces for free

If you bought a set new and a piece was missing from the box or arrived broken, LEGO will usually send a replacement free of charge. Which form you use depends on the problem:

  • Piece missing from a new set

    Use LEGO's Missing Pieces form. Search by set number, choose the piece from the set's list and send the request. Each set needs its own request.

  • Piece broken or faulty in a new set

    Use the Broken Pieces form and describe the problem. LEGO may ask you to return the piece or show a receipt, so keep both for now.

LEGO's US shop terms describe this free Bricks & Pieces service for the United States and Canada, and say LEGO may change it without notice. Other countries have their own LEGO site, so check there. Requests that look false or repeated can be refused.

Not covered: pieces you lost after building, pieces from second-hand sets, and most retired parts. For those, buy the piece using one of the options below.

How to order missing LEGO pieces online

When a free replacement is not an option, there are three common ways to buy LEGO spare parts. Which one is best depends on how old the piece is and how many you need.

WhereBest forGood to know
LEGO free replacementPieces missing or broken in a new setFree, one request per set, slower than buying
LEGO Pick a BrickNew pieces in current colors, bought straight from LEGOBrowse by piece type and color, or upload a list of up to 400 different pieces. In the US a $7 service fee applies to orders under $14.

Tip: use the finder's Copy List button to keep part numbers, colors and quantities together. Ordering the wrong shade is the most common mistake when buying replacement LEGO pieces.

LEGO part numbers explained

You will see a few different numbers when you look for LEGO replacement parts. Knowing which is which saves a lot of confusion:

Set number
The product number on the box, such as 10316. Everything starts here.
Design ID (part number)
The shape, in any color, often molded on the piece itself. For example 3001 is a 2x4 brick. This finder lists design numbers with a color name.
Element ID
A longer number for one shape in one color, printed in the parts list at the back of most modern instructions.

Color names also differ between LEGO, BrickLink and other catalogs, so match colors by eye as well as by name. Not sure of a color? Try the LEGO color identifier, or look a number up with the part number lookup.

LEGO parts lists for your set

Every set in our catalog has its own page with a full inventory, for example the Rivendell 10316 parts list. Use the LEGO set finder to find a set by name or number and browse its parts. Most building instructions from LEGO also include a parts list on the last pages, and the instruction PDFs can be downloaded from LEGO's website.

Have a box of mixed pieces instead? The brick pile scanner and what can I build tool show which sets your pieces can rebuild and which parts you are still missing.

LEGO replacement parts FAQ

Can I get missing LEGO pieces for free?

+

Usually, if the set was bought new. LEGO replaces pieces that were missing or faulty in a new set through its Missing Pieces and Broken Pieces forms. LEGO’s US terms describe this free Bricks & Pieces service for the US and Canada and say LEGO can change it at any time, so check the LEGO site for your country. Pieces you lost later, or pieces for second-hand sets, normally have to be bought.

How do I find the part number of a missing LEGO piece?

+

Enter your set number in the finder above to load the set’s full parts list, then look for the piece by shape and color. The parts list at the back of most modern LEGO instructions also shows each piece with its element ID. If you have a similar loose piece but no set number, identify it by photo instead.

What is the difference between a LEGO design ID and an element ID?

+

The design ID describes the shape only and is often molded on the piece itself, for example 3001 for a 2x4 brick. The element ID is a longer number for one shape in one color, and it is what LEGO prints in the instructions parts list. The finder shows the design number together with the color name.

How long do LEGO replacement parts take to arrive?

+

LEGO’s US terms aim for 7–10 days to the continental US and 17–22 days to Canada for free Bricks & Pieces orders. Other countries and Pick a Brick orders have their own delivery times, shown at checkout.

Can I request replacement pieces for several sets at once?

+

Not in one free request: LEGO asks for a separate Missing Pieces or Broken Pieces request for each set. If you are buying pieces, Pick a Brick lets you upload a list of up to 400 different pieces at once.

Does LEGO replace pieces from old or retired sets?

+

The free service is meant for new sets, and older pieces are often no longer made. For retired sets, check Pick a Brick first, then marketplaces such as BrickLink or Brick Owl, where sellers offer new and used pieces in older colors.

Why is a minifigure not in the set’s parts list?

+

The finder lists the bricks and parts from the set inventory, without spare pieces, and does not list complete minifigures yet. To find a minifigure, use the minifigure identifier.

Is this LEGO replacement parts finder made by LEGO?

+

No. BrickFinder is an independent, free tool and is not affiliated with or endorsed by the LEGO Group. Free replacements and Pick a Brick orders are handled by LEGO on lego.com.
